model-council-mcp

An MCP server that routes a question to a council of AI models — local (Ollama, vLLM, TRT-LLM, SGLang) and cloud (OpenAI, Anthropic, X.AI Grok) — and synthesizes their answers in five configurable modes:

Mode	What you get
`individual`	Each model's raw answer, side by side
`categorized`	Judge groups responses into common agreement, complementary insights, and conflicting positions
`deconflicted`	Iterative loop — judge re-questions the council on each conflict until resolved or rounds exhausted; returns a deconfliction score (0–100 %)
`pooled`	Delphi-style — judge distils all answers into a neutral, deduplicated pool (no counts, no attribution, no ranking); members reconsider against it and answer freshly. No winner is forced, so genuine divergence is preserved rather than collapsed by social proof
`dialectic`	Thesis → antithesis → synthesis — members defend their initial pick and argue why the alternatives aren't better; the judge compiles a balanced pros/cons dossier per option; members then re-select a ranked top-3 having weighed both sides

Example use cases

High-stakes technical decision — ask_council(..., mode="dialectic") to see each option argued for and against before a synthesized, ranked recommendation (attach the relevant file with files=[…]).
Reduce single-model bias — mode="pooled" (Delphi) so a minority-but-correct answer is preserved instead of averaged away by the loudest model.
Spot disagreement fast — mode="categorized" to have a judge sort answers into agreement, complementary insight, and genuine conflict.
Code / design review across models — attach a file (files=["src/auth.ts"]) or a local diff (git_ref="uncommitted") and ask the whole council to critique it; use context to add constraints ("must be OWASP-clean").
Local-only, offline second opinions — fan a prompt across every model you already run in Ollama; no cloud, no API keys.
Mix your subscriptions — put Claude (Opus/Sonnet/Haiku) and ChatGPT (via Codex) side by side on the same question, billed to plans you already pay for.
Long runs without blocking — kick off a deconfliction over slow local models with ask_council_async, keep working, then get_council_result(job_id).

Install as a Claude Code plugin (recommended)

This repo is a self-contained Claude Code plugin — the server is bundled into a single zero-dependency file (bundle/server.cjs), so it runs offline against local models with no npm install step.

# 1. Add this repo as a marketplace (from GitHub)
/plugin marketplace add tsarihan/model-council-mcp

# 2. Install the plugin
/plugin install model-council@model-council

Zero-config — it just works. On first run the plugin detects your environment and auto-populates the council with everything usable: every local Ollama chat model, your top curated Ollama :cloud models, and — if you're logged into them — Claude (via the local claude CLI) and ChatGPT (via the local codex CLI). It tells you what it found, warns that cloud/subscription members use your own quotas, and lets you delete any you don't want. Deletions and setup persist across reloads. Ask a question immediately — no setup required.

On a new session the plugin prints a one-line status (council size, Ollama up/down, which CLIs are installed).
Run /model-council:status any time for the full readout — detected models, CLI login state, per-provider concurrency, and quota usage.
Run /model-council:setup to pick your subscription tiers with an interactive menu.

Everything is optional and adjustable from /plugin → Configure. API keys are stored in your system keychain.

Local development / test install:

# Validate the manifest
claude plugin validate .

# Load without installing (dev loop)
claude --plugin-dir /path/to/model-council-mcp

Configurable options (prompted at install)

These are all set from /plugin → Configure in Claude Code (or the equivalent env vars shown for standalone installs — e.g. REQUEST_TIMEOUT_MS for the timeout, CLOUD_CONCURRENCY for the cloud override). They persist across reloads.

Option	Purpose	Default
Ollama address	Base URL of your Ollama server	`http://localhost:11434`
Council models	Pin specific models, or leave blank to auto-use all Ollama models	(empty → auto)
Auto-discover council	Use all Ollama chat models (local + `:cloud`) when none pinned	`true`
Claude tier	`free` / `pro` / `max5x` / `max20x` — cloud access + 4/8/12 parallel Claude calls (starting points — Anthropic publishes usage multipliers, not a session cap)	`pro`
ChatGPT tier	`free` / `plus` / `pro5x` / `pro20x` — 6/8/12 parallel Codex calls (Plus = the Codex CLI's own default of 6; OpenAI publishes no per-plan concurrency)	`plus`
Ollama tier	`free` / `pro` / `max` — `free` = local only; `pro`/`max` = cloud + 3/10 concurrency (published hard caps, queue-then-reject)	`pro`
Grok tier	`free` / `supergrok` / `premiumplus` / `heavy` — cloud access + Grok concurrency (defaults to `free`, opt-in)	`free`
Judge model	Categorizer/deconflicter, or `auto` (largest)	`auto`
Default response mode	`individual` / `categorized` / `deconflicted` / `pooled` / `dialectic`	`categorized`
Max deconfliction rounds	1–10	`3`
OpenAI / Anthropic / X.AI API key	Enable cloud models (stored in keychain)	—
vLLM / TRT-LLM / SGLang servers	`name:host:port` entries	—
Max response tokens	Tokens per completion	`16000`
Default reasoning effort	How hard every member and the judge think: `none` … `max`. Clamped per-backend; override per call with `ask_council`'s `reasoning_effort`. See Reasoning effort.	`high` on a new install; empty = each model's own default
Per-request timeout (text)	Wall-clock timeout (ms) for a single completion on text-only calls before the member is recorded as timed-out. Default raised to 5 min because local Ollama models run sequentially. Honoured verbatim by every provider, including the subscription CLIs (no 300s floor). Set via `REQUEST_TIMEOUT_MS`, or at runtime via the `set_council_timeouts` MCP tool. Max 3600000 (60 min), per completion.	`300000` (5 min)
Per-request timeout (repo)	Timeout used instead of the text timeout when `full_repo_access` is set — the CLI member Read/Grep/Globs the repo tree, materially longer. Set via `REPO_REQUEST_TIMEOUT_MS`, or at runtime via `set_council_timeouts`. Max 3600000 (60 min), per completion.	`600000` (10 min)
Cloud concurrency (override)	Optional; caps all cloud pools, overriding the per-tier limits	(unset → tiers)
Local concurrency	Simultaneous local requests (0 = unlimited)	`1`
Completion retries	Retries on an empty/failed response	`3`

Subscription tiers, auto-population & detection

The council mixes four kinds of member, each gated by a subscription tier so it never quietly burns quota you don't have:

Provider	Tiers	`free` means	Reference file
Ollama	`free` / `pro` / `max`	local models only (no `:cloud`)	`config/subscriptions.json`
Claude (via `claude` CLI)	`free` / `pro` / `max5x` / `max20x`	no Claude members	″
ChatGPT (via `codex` CLI)	`free` / `plus` / `pro5x` / `pro20x`	no ChatGPT/Codex members	″
Grok (via `grok` CLI)	`free` / `supergrok` / `premiumplus` / `heavy`	no Grok members	″

Grok defaults to free even when the grok CLI is installed and logged in — unlike Claude/ChatGPT, it's opt-in, since it's a newer provider added on top of an existing install base. Set GROK_TIER (or run /model-council:setup) to turn it on.

Per-provider concurrency. Each subscription gets its own concurrency ceiling — Claude 4/8/12 on Pro/Max-5×/Max-20×, ChatGPT 6/8/12 on Plus/Pro-5×/Pro-20×, Ollama-cloud 3 on Pro / 10 on Max — so one slow, tightly-rate-limited provider can't starve another. Only Ollama's numbers are published hard caps (queue-then-reject, not raisable client-side); Claude and ChatGPT publish usage multipliers (5×/20×) over a shared throttled pool and no per-plan concurrency, so their ceilings are researched starting points that scale with the tier — safe to edit upward until you see 429s or quota burn. Tier→limit mappings (with a concurrencyBasis note recording exactly this provenance), curated cloud models, and provider model names all live in config/subscriptions.json — edit it and pull to pick up new plans/models.
Detection. On boot (and on council_status) the server checks: is Ollama reachable, does your plan reach :cloud, is the claude CLI installed and logged in (a locked-down probe), is the codex CLI signed in (codex login status), is the grok CLI installed and logged in (a locked-down probe, like Claude — the CLI has no dedicated login-status subcommand). Only usable providers are auto-added; the rest get a hint (e.g. "Codex CLI installed but not signed in — run codex login").
It persists. Your tier choices, member edits, and any configure_council setting you set (judge model, response mode, max deconfliction rounds) are saved to ~/.config/model-council/state.json (override with MODEL_COUNCIL_STATE), so they survive plugin reloads — each field only persists once you've explicitly set it at least once; an untouched field falls back to its env-var/default as before. Known limitation: writes are atomic (a torn/partial file is never observed) but not cross-process locked — two MCP server processes pointed at the same state file and edited at close to the same instant can each read-modify-write past the other, and whichever write lands second wins for any field only it touched. Harmless for the common case (one server process per session); if you deliberately run multiple concurrent sessions against a shared state file, prefer giving each its own MODEL_COUNCIL_STATE.
Works standalone too. The auto-config, council_status, and setup_council tools all work for a plain claude mcp add / MCP-store install; only the SessionStart welcome line and the /model-council:* slash commands are Claude-Code-plugin-only sugar.

Cloud and subscription members run under your own subscription quotas via the sanctioned first-party CLIs. council_status always shows a quota warning listing which paid providers are in the council. Reusing a subscription token against a raw vendor API from a third-party app is a separate, prohibited thing — this plugin does not do that.

Install as a standalone MCP server (any MCP client)

The server is a single zero-dependency file (bundle/server.cjs) — no npm install, no npx. Clone the repo and point any MCP client at it:

git clone https://github.com/tsarihan/model-council-mcp.git

Then in your client's MCP config (Claude Code's ~/.claude.json → mcpServers, Cursor, Cline, etc.) — point command at the cloned bundle:

{
  "mcpServers": {
    "model-council": {
      "command": "node",
      "args": ["/absolute/path/to/model-council-mcp/bundle/server.cjs"],
      "env": {
        "OLLAMA_ADDRESS": "http://localhost:11434",
        "RESPONSE_MODE": "categorized"
      }
    }
  }
}

For Claude Code specifically, you can also add it directly:

claude mcp add model-council -s user -- node /absolute/path/to/model-council-mcp/bundle/server.cjs

Claude via your subscription (first-party CLI)

Set CLAUDE_CLI=true to add council members that run through the locally-installed Claude Code CLI (claude -p) instead of the Anthropic API. Inference runs under whatever your claude CLI is logged in with — typically your own Claude Pro/Max subscription — so these members don't consume API credits. They appear as claude-cli:opus, claude-cli:sonnet, etc.

Behavior & requirements

The claude CLI must be installed and logged in (claude → /login, or claude setup-token). Set CLAUDE_CLI_PATH if it isn't on PATH.
Each call shells out to claude -p with all tools disabled (--tools ""), MCP disabled (--strict-mcp-config, so it can't recurse into this plugin), and sessions not persisted — a clean single text answer.
ANTHROPIC_API_KEY / ANTHROPIC_AUTH_TOKEN are stripped from the nested call, because the CLI silently prefers an API key over the subscription. So these members stay subscription-billed even if you also set an API key for the regular anthropic: provider.
They are not auto-discovered — add them explicitly via configure_council or COUNCIL_MODELS (e.g. claude-cli:opus), so they don't quietly draw down your subscription.

Where it works: anywhere the claude CLI actually executes — the Claude Code CLI, or the Claude Desktop app on a machine that also has the CLI. With /remote-control on your CLI, driving it from the Claude web/mobile code tab still runs claude -p on your machine, so it works there too. It does not work for a remotely-hosted copy of this server (no local CLI), and it can't borrow the Claude app's subscription directly (no client supports MCP sampling yet).

This uses the sanctioned first-party CLI under your own subscription, for your own use. High-volume automated fan-out can hit your subscription's rate limits — keep CLOUD_CONCURRENCY modest (these members use the cloud pool). Reusing a subscription token against the raw Anthropic API from a third-party app is a separate thing and is prohibited; this feature does not do that.

Open-weight models with genuine repo access (Ollama via the `claude` CLI's harness)

Every other Ollama/OpenAI-compatible/API-keyed provider gets a flattened text completion with no tool use at all — full_repo_access (see below) only ever meant something for claude-cli/codex-cli, because they're the only members with an agentic harness to grant tools within. CLAUDE_CLI_OLLAMA_MODELS closes that gap for any Ollama model (local or :cloud) by reusing the exact same harness: it points the claude CLI's own ANTHROPIC_BASE_URL at Ollama's native Anthropic-Messages-API-compatible endpoint (/v1/messages, confirmed live to return authentically Anthropic-shaped JSON) instead of the real Anthropic API, then drives it with the identical --tools Read,Grep,Glob --add-dir <repo> allowlist as the real subscription CLI — same permission enforcement, same --strict-mcp-config, same everything, just a different backend.

CLAUDE_CLI_OLLAMA_MODELS=glm-5.2:cloud,kimi-k2.7-code:cloud,deepseek-v4-pro:cloud

They appear as claude-cli/claude-cli-ollama:glm-5.2:cloud (note the serverId — this is a separate registration from the real subscription CLI, so it never shares its id, its label, or its concurrency pool).

Behavior & requirements

These members are NOT Claude. They're open-weight models answering through Claude Code's harness purely to get real tool use; list_models/get_council_config label them "<model> (via claude CLI harness, <address>)", never "Claude ..." (and any basic-auth credentials in the address are redacted from that label).
Ambient env isolation. Because harness mode repoints the CLI at a non-Anthropic (possibly remote) host, it strips every ambient backend-redirect/credential var from the subprocess — the CLAUDE_CODE_USE_BEDROCK/VERTEX/FOUNDRY selectors (which otherwise outrank ANTHROPIC_BASE_URL and would send your repo to that cloud), ANTHROPIC_CUSTOM_HEADERS, OAuth/Foundry tokens, and provider base-url overrides — so nothing inherited from the server's environment can redirect the prompt to, or ride along as a secret to, the harness host. (The real subscription CLI leaves those selectors alone, so a legitimately Bedrock/Vertex-hosted Claude Code still works.)
Requires the claude CLI installed (same binary as the real subscription CLI — no separate install) and a running Ollama server whose version serves /v1/messages natively (confirmed on Ollama 0.32.4; older versions may lack it).
Concurrency is bucketed under Ollama's own pools (ollama-cloud for :cloud models, local otherwise) — not the Claude subscription's pool — so this can't starve (or be starved by) real Claude subscription members.
Auto-populated by default. When Ollama cloud is reachable and the claude CLI is installed, curated :cloud models from subscriptions.json are automatically routed through the harness (tool access). CLAUDE_CLI_OLLAMA_MODELS adds explicit models on top. Existing users with persisted ollama:*:cloud members are migrated automatically on next boot.
Full repo contents can be sent to whichever Ollama backend answers — a local Ollama model keeps this fully offline, but a :cloud model sends repo contents to that cloud provider the same way full_repo_access sends them to Claude/ChatGPT's cloud for the first-party CLIs. Don't enable full_repo_access on a repo containing secrets you wouldn't send to that provider.

Where it works: same as the real Claude CLI above — anywhere the claude binary actually executes.

ChatGPT via your subscription (first-party Codex CLI)

Set CODEX_CLI=true to add a council member that runs through the locally-installed Codex CLI (codex exec) instead of the OpenAI API. Inference runs under whatever your codex CLI is signed in with — typically your own ChatGPT subscription (codex login → Sign in with ChatGPT) — so this member doesn't consume API credits. It appears as codex-cli:default (or codex-cli:<model>).

Behavior & requirements

The codex CLI must be installed and signed in (codex login). Set CODEX_CLI_PATH if it isn't on PATH.
Each call shells out to codex exec in a read-only sandbox (--sandbox read-only) with no approval prompts (approval_policy=never), run in an empty ephemeral working dir so the agent has nothing to explore, and reads the final answer from -o <file> — a clean single text answer, no file changes.
OPENAI_API_KEY / CODEX_API_KEY are stripped from the nested call, because the CLI silently prefers an API key over the ChatGPT login. So this member stays subscription-billed even if you also set an API key for the regular openai: provider.
Use CODEX_CLI_MODELS=default to let Codex pick its configured model, or name specific ones (e.g. gpt-5-codex). It is not auto-discovered — add codex-cli:default explicitly via configure_council or COUNCIL_MODELS.
Codex is a coding agent, so answers carry a coding-agent flavor (concise, implementation-oriented) even on general questions — useful as a distinct voice in the council, but not a neutral generalist.

Where it works: same as the Claude CLI above — anywhere the codex binary actually executes (this machine, or a /remote-control-driven CLI running on your machine). It does not work for a remotely-hosted copy of this server.

Same rules as the Claude CLI: sanctioned first-party surface under your own subscription. Reusing a subscription token against the raw OpenAI API from a third-party app is a separate, prohibited thing; this feature does not do that.

Grok via your subscription (first-party Grok Build CLI)

⚠️ grok-cli members are currently DISABLED (v0.2.64). grok's tool lockdown does not work: --tools '' is read by the CLI as "flag unset" and enables its full built-in tool set — including a shell — while --permission-mode bypassPermissions (required for headless use) auto-approves every call. This was verified live with a proof-of-execution marker, and --tools none was verified to fail the same way. Because a grok judge is fed every other member's untrusted text, a single crafted line was arbitrary command execution as your user. No replacement value has been verified yet, so the provider now fails closed with a clear error rather than shipping an unverified guard. GROK_CLI_UNSAFE_ACCEPT_RCE=true re-enables it for testing only.

Set GROK_CLI=true (or a GROK_TIER above free) to add council members that run through xAI's locally-installed Grok Build CLI (grok -p / --prompt-json) instead of the X.AI API. Inference runs under whatever your grok CLI is logged in with — typically your own SuperGrok / X Premium+ / Heavy subscription — so these members don't consume API credits. They appear as grok-cli:grok-4.5 (or grok-cli:<model>).

Behavior & requirements

The grok CLI must be installed and logged in. Set GROK_CLI_PATH if it isn't on PATH.
Each call shells out to grok with all tools disabled (--tools '') and --permission-mode bypassPermissions (required for headless use — without it the CLI silently cancels the turn instead of completing).
XAI_API_KEY is stripped from the nested call, because the CLI accepts it as an alternate auth path that would otherwise switch billing to per-token instead of the subscription.
Images are passed as native --prompt-json content blocks (no Read-tool or -i-flag workaround needed — the CLI accepts structured image content directly).
A text-only prompt (the common case) is written to a temp file and passed via --prompt-file rather than inline, avoiding the OS argv-length limit a large context/files/git-diff attachment or judge prompt could otherwise hit. An image-bearing call still passes --prompt-json inline (no file-based channel exists for that content-block shape), so the same argv-length exposure remains there, bounded by the existing image size caps.
Unlike Claude/ChatGPT's CLI members, Grok defaults to free (opt-in) — set GROK_TIER above free or GROK_CLI=true explicitly to add it to the auto-populated council, since this is a newer provider added on top of an existing install base.

Where it works: anywhere the grok binary actually executes (this machine, or a /remote-control-driven CLI running on your machine). It does not work for a remotely-hosted copy of this server.

Same rules as the Claude/Codex CLIs: sanctioned first-party surface under your own subscription. Reusing a subscription token against the raw X.AI API from a third-party app is a separate, prohibited thing; this feature does not do that.

OpenAI-compatible server format

Comma-separated list of name:host:port entries.
You can run multiple servers on different ports (e.g. different models on the same GPU host):

VLLM_SERVERS=gpu1:192.168.1.10:8000,gpu2:192.168.1.10:8001
TRTLLM_SERVERS=trt-main:192.168.1.20:8000
SGLANG_SERVERS=sgl1:192.168.1.30:30000

Full URLs also work: gpu3:http://10.0.0.5:9000

Default ports: vLLM → 8000, TRT-LLM → 8000, SGLang → 30000

Council defaults

Variable	Description	Default
`COUNCIL_MODELS`	Comma-separated model IDs	(empty — use `configure_council`)
`JUDGE_MODEL`	Judge model ID or `auto`	`auto` (largest council member)
`RESPONSE_MODE`	`individual` \| `categorized` \| `deconflicted` \| `pooled` \| `dialectic`	`categorized`
`MAX_DECONFLICT_ROUNDS`	Max deconfliction iterations	`3`
`COUNCIL_SESSIONS`	How many Claude Code sessions you run AT ONCE on this machine. Subscription pool ceilings (chatgpt/claude/grok/ollama-cloud) are divided by this so N per-process servers together stay near your plan's intended concurrency instead of running N× over it; API-key and local pools are untouched.	`1`
`HARNESS_TOOL_CONCURRENCY`	Parallel tool executions inside one claude-cli member call (`CLAUDE_CODE_MAX_TOOL_USE_CONCURRENCY` on the spawn). Set explicitly on every spawn so members never inherit a throttle you set on your own interactive session to fight 429s. Seeded to `16` whenever the state key is absent — fresh installs and upgrades from versions without the knob — then yours to edit (`configure_council`'s `harness_tool_concurrency`, 1–64). claude-cli members only: codex members spawn no child agents (and codex's `agents.*` flags are rejected outright on versions with multi-agent V2 active), grok has no equivalent.	seeded `16`
`WEB_ACCESS`	`true` → council members search the web by default instead of answering from training data. See Web access. Off by default; per-call `web_access` overrides it.	`false`
`REASONING_EFFORT`	Default reasoning depth for every member and the judge: `none` \| `minimal` \| `low` \| `medium` \| `high` \| `xhigh` \| `max`. See Reasoning effort — levels a backend doesn't support are clamped, never errored. Outranks the first-run seed below.	(unset — but a brand-new install* seeds `high`)*

Performance & output

Variable	Description	Default
`MAX_TOKENS`	Max output tokens requested per completion. Clamped per-model to fit each server's context window (Ollama `/api/show`, OpenAI-compatible `max_model_len`), so a generous value gives longer answers on large-context models without risking an over-context request. CLI members (`claude-cli`/`codex-cli`/`grok-cli`) ignore it — output is subscription-managed. Raise for even longer answers (slower/costlier, multiplied across members × rounds).	`32768`
`CLOUD_CONCURRENCY`	Max simultaneous requests to cloud members (Ollama cloud `:cloud`/`-cloud`, OpenAI, Anthropic, X.AI). Ollama cloud needs Pro (3 concurrent) or Max (10)	`3`
`LOCAL_CONCURRENCY`	Max simultaneous requests to local models; `1` runs them one at a time to avoid contention, `0` = unlimited	`1`
`COMPLETION_RETRIES`	Attempts per completion before giving up on an empty/failed response	`3`
`REQUEST_TIMEOUT_MS`	Per-completion wall-clock timeout (ms) for text-only calls. Default 5 min — local Ollama models run sequentially, so a busy box needs headroom. Honoured verbatim by every provider, including the subscription CLIs (no 300s floor). A member cut by this timeout is flagged in the result (`timeoutNotice`); raise it or use `set_council_timeouts`. Clamped to 1000–3600000 (60 min) with a boot warning if outside.	`300000`
`REPO_REQUEST_TIMEOUT_MS`	Per-completion timeout (ms) used instead when `full_repo_access` is set — repo-reading completions (CLI member Read/Grep/Glob) run longer. Clamped to 1000–3600000 (60 min) with a boot warning if outside.	`600000`
`DECONFLICT_VERBOSE`	`true` → deconflicted results include per-round detail by default	`false`

Input send-caps (bound what the tool feeds the council per call — a large attachment is multiplied across every member × round, so these are a real memory/latency/token amplifier, not just a per-request size). Raise them for a council of large-context models; the practical ceiling is the smallest member's context window, so sending ~1 MB (~300K tokens) to a 256K-context local member makes that member error cleanly (PromptTooLargeError) while cloud members still answer:

Variable	Description	Default
`MAX_CONTEXT_KB`	Inline `context` string cap	`1024` (1 MB)
`MAX_TOTAL_KB`	Total across all attached `files`	`1536` (1.5 MB)
`MAX_FILE_KB`	Per-file cap	`512`
`MAX_FILES`	Max number of attached files	`32`
`MAX_QUESTION_KB`	`question` string cap (large text belongs in `context`/`files`)	`256`

Note on Ollama input context (num_ctx). The tool does not set num_ctx — it inherits your Ollama server's default. To let local models actually ingest large context, set OLLAMA_CONTEXT_LENGTH on the Ollama server (e.g. 262144 for 256K); the tool reads each model's real max from /api/show and fits output to it. Leaving num_ctx to the server keeps a model loaded at one stable context size (no per-request reloads) — deliberately, so the tool never churns model loads.

The council queries members in parallel but respects these concurrency limits — cloud members share one pool and local members another, so a large council never exceeds your Ollama cloud plan's concurrent-request cap, and local models can be run sequentially to avoid GPU contention. Each pool's limit is enforced process-wide, not per-call: two ask_council/ask_council_async requests in flight at once (e.g. via the 20-slot async job queue) that both touch the same provider still share that provider's single ceiling rather than each getting their own — a concurrent request can end up waiting on a slot another request is holding, which is expected serialization, not a hang. This applies equally to the judge — categorization, pooling, dossier-building, and final synthesis calls draw from the same pool as the member they're judging, not a separate unbounded channel.

Returns model IDs, parameter size, family, disk size — everything you need to fill configure_council.

`configure_council`

Update the council at runtime (changes persist for the session).

{
  "models": ["ollama:llama3", "ollama:mistral", "openai:gpt-4o"],
  "judge_model": "openai:gpt-4o",
  "response_mode": "deconflicted",
  "max_deconflict_rounds": 4,
  "reasoning_effort": "high"
}

All fields are optional — only supplied fields are updated. models is capped at 100 entries. output_file_location (absolute path) sets where per-ask member scratch directories are created — default the OS temp directory; stale run dirs older than 7 days are swept at boot. reasoning_effort sets the council-wide default reasoning depth (see Reasoning effort); it persists across reloads and is overridable per call on ask_council. Pass "auto" to clear it back to each model's own default — distinct from "none", which actively asks every backend for no reasoning. harness_tool_concurrency (1–64) sets how many tool executions one claude-cli member may run in parallel inside its own session — see HARNESS_TOOL_CONCURRENCY in the env table for why it is set explicitly on every spawn.

Parameter names are strict. An unrecognized parameter is rejected with an error, never silently ignored — so a call that doesn't do what you meant fails loudly instead of returning a cheerful "status": "updated" while changing nothing. The error names the offending key, suggests the intended one, and lists the valid parameters. Two easy slips worth knowing: the council is set with models but reported (by get_council_config / council_status) as members; and the response mode is response_mode here but mode on ask_council.

`ask_council`

Send a question to the full council.

{
  "question": "What is the best way to handle errors in a distributed system?",
  "mode": "deconflicted",
  "max_deconflict_rounds": 3
}

mode, max_deconflict_rounds, and reasoning_effort override the configured defaults for this call only. output_file (absolute .md/.txt/.json path) has the server write the complete result to disk after the run — every member's full response, judge output, sources, usage, and member-written files inlined — because members themselves can never write to caller-chosen paths. member_file_output grants each claude-cli/codex-cli member a private, server-created scratch directory and tells it to save long findings there as .md files; they are collected into memberFiles after the run (and inlined into output_file reports). It defaults ON for full_repo_access/web asks — exactly where full findings otherwise get truncated to fit one response — and OFF for plain asks; pass true/false to force either way. Write access is confined per-harness, verified live: claude-cli gets the Write tool gated by an Edit(//scratch/**) permission rule (the repo under review stays read-only — probed: the scratch write landed, the repo write was blocked in the same call), and codex-cli flips to its workspace-write sandbox with the scratch dir as the workspace ("sandbox permissions deny writes outside the workspace", with reads unconfined so repo review keeps working) — except when the repo itself lives inside the OS tmpdir, where codex stays read-only because workspace-write would make tmp writable too. In deconflicted mode, set "verbose": true to include the initial categorization, every member's per-round responses, and the round-by-round re-categorization alongside the final synthesis. In pooled mode, "verbose": true adds the initial (round-0) raw member responses.

Reasoning effort. "reasoning_effort" sets how hard the council thinks, on one canonical scale — none · minimal · low · medium · high · xhigh · max:

{
  "question": "Design a migration path off this schema.",
  "mode": "dialectic",
  "reasoning_effort": "max"
}

Effort resolves in three tiers, strongest first: member_efforts (per model, per call) ▸ reasoning_effort (per call) ▸ the configured default. So one setting governs the whole ask by default — deeply-reasoned answers reconciled by an equally deep judge — while a member that prices effort very differently can be pinned individually:

{ "question": "…", "reasoning_effort": "xhigh", "member_efforts": { "gpt-5.6-sol": "medium" } }

Keys match a member (or the judge — it's a model too) by full label, model name, or unique substring; an unknown or ambiguous key is rejected loudly, never silently dropped. This exists for a measured reason: the codex member at max ran 25× its own low-effort latency (638s worst vs 17s), while the others stayed usable — one dial for the whole council forces a choice between starving the fast members and stalling on the slow one.

A brand-new install starts at high — a council is worth more when its members actually think. That seed is written to state.json on the first run only, so from then on it is an ordinary setting you own: change it with configure_council, or pass "auto" there to clear it back to each model's own default. It is deliberately not the plugin option's default value, because a userConfig default would re-apply on every update; an install that already exists and never set an effort keeps running at model defaults, so upgrading never silently changes how hard your council thinks or how much quota it burns. An explicit REASONING_EFFORT outranks the seed.

Each backend supports a different slice of the scale, so a level it doesn't accept is clamped to its nearest supported one, never errored — a council-wide setting must not shrink a mixed council to whichever members happen to share a vocabulary. Ties clamp downward (the cheaper side).

Member type	Knob used	Levels it accepts	Example clamp
`claude-cli`	`--effort`	`low` … `max`	`none` → `low`
`codex-cli`	`-c model_reasoning_effort=`	`none`, `low` … `max`	`minimal` → `none` (its parameter enum advertises `minimal`, but the model itself rejects it)
`grok-cli`	`--reasoning-effort`	`low`, `high`	`max` → `high`, `medium` → `low`
`ollama`	`think:`	`low`, `medium`, `high`, `max`	`xhigh` → `high`; `none` → `think: false`
`openai` / `vllm` / `trtllm` / `sglang`	`reasoning_effort`	`none` … `xhigh`	`max` → `xhigh`
`anthropic` (API key)	extended thinking `budget_tokens`	derived from the level	`none`/`minimal` → no thinking

Two members that can't honour the request at all are handled rather than dropped: an Ollama model with no thinking support, and an OpenAI-compatible server that rejects the parameter, are each retried once without it, so they still answer (at their own depth) instead of failing the call.

Cost. Higher levels buy depth with time and subscription quota, and the multiplier is members × rounds — a max run of a 5-member deconflicted council is a materially bigger spend than a low one. set_council_timeouts may need raising alongside it.

Which round produced an answer. Every member response carries a phase tag naming the round it came from, so a caller reading raw JSON can tell the rounds apart without inferring it from the surrounding field name:

`phase`	Round
`thesis`	Round 0 — each member's initial, independent answer (every mode)
`antithesis`	`dialectic` — defend your own pick, argue the alternatives are worse
`synthesis`	`dialectic` — final ranked re-selection after weighing the pros/cons dossier
`reconsidered`	`pooled` — a fresh answer given after seeing the neutral pool
`deconflict`	`deconflicted` — a re-question aimed at the open conflicts; `round` carries which pass (1-based)

This is defense in depth, not the primary mechanism. Rounds are already separated structurally: each is its own awaited call whose results land in a dedicated array at a fixed per-member index, so a slow member's answer can never arrive late and be swept into the next round — a member that times out simply leaves an errored entry in its own round's slot (and sets judgeDegraded). The tag puts that round on the record rather than leaving it implied by the container, so a future refactor that merges or forwards responses between collections can't silently turn a thesis into an antithesis. The dialectic dossier prompt — the one place two rounds are shown to the judge together — labels each entry from its own phase for the same reason.

Web access. "web_access": true lets members SEARCH THE WEB for that call, so they research current facts instead of answering from training data. Off by default — it costs latency and subscription quota, and it pulls untrusted text into the council.

{ "question": "Which US steakhouses currently hold three Michelin stars?", "web_access": true }

Who can actually research depends on whether a member has an agentic tool loop to grant a search tool inside:

Member	How it researches
`claude-cli`	`--tools WebSearch,WebFetch` plus `--allowedTools` — both are required; the first enables the tool, the second permits its use
`codex-cli`	`-c tools.web_search=true` (`codex exec` has no `--search` flag)
`grok-cli`	web tools re-enabled in `--tools`; names unverified, and it fails closed if the guess is wrong
bare `ollama:*`	automatically re-pointed through the claude-CLI harness for the call, since Ollama serves an Anthropic-Messages endpoint — so it researches too
`openai` / `xai` / `vllm` / `trtllm` / `sglang`	cannot — one flattened completion, no tool turn

Every result then carries a webRouting block naming researched, fromMemory (with the reason), and routedViaHarness. That exists so a partly-researched council is never read as a fully-researched one — the judge reconciles those answers as peers, so the split has to be visible.

Known limitation (verified live). An open-weight model driven through the harness may emit its OWN native tool-call markup as plain text instead of an executable tool call — observed with kimi-k3:cloud at --effort max, while the same call at low searched correctly and cited a source. No search runs in that case, so the provider now rejects such a reply as a failed completion (retried, then reported as a member error) rather than letting the markup reach the judge as a position.

Timeouts adapt to the member, not the other way round. Throughput across a mixed council spans roughly 20× — a local model on Apple silicon runs ~10 tok/s, Ollama cloud ~200, the hosted APIs 20–50 — so a single per-completion deadline is either wasted on the fast members or a guillotine for the slow ones. Two things follow. Calls with full_repo_access or web_access use the longer REPO_REQUEST_TIMEOUT_MS budget, because both pull far more content (a repo tree, several fetched pages) and output length scales with it. And any member that has genuinely needed longer before is given at least that again, learned from its own history rather than configured — capped, and only ever raised by a successful round, so a timeout can never inflate the budget that caused it. The history is kept per workload, because the workloads differ by more than the models do: a member that answers a question in 8s can legitimately need minutes to review a repo. A plain measurement does raise the heavy floor (heavy work is a superset — it cannot be faster), but a heavy measurement never raises the plain one, since a long repo review says nothing about a short question.

Capability detection. A member on an engine the council has no built-in knowledge of is probed, not refused — one small completion to find a working harness, plus (only when web access is wanted) one tool-call probe, since a model can answer perfectly and still be unable to execute a tool call. The result is written to state.json harnessCapability and reused, so the cost is paid at most once per model per 30 days, across restarts and plugin updates. A timeout is recorded as inconclusive rather than as a verdict, so a slow machine never permanently condemns a capable model.

Built for many sessions at once. Several Claude Code sessions each spawn their own council server against the same ~/.config/model-council — and that is now a first-class deployment, not an accident. A member list changed in one session is re-adopted by every running session on its next ask (the one setting with account-wide quota cost and no per-call escape); all other settings apply to the changing session now and to new sessions later, and the tool replies say so instead of overclaiming. Set COUNCIL_SESSIONS to your usual session count so the subscription concurrency ceilings are shared rather than multiplied. Background jobs carry their owner's pid, so one session's reload never falsifies another's in-flight work, any session can poll any session's jobs, and retention never lets a burst of fresh runs evict a finished-but-unfetched result. A corrupt state.json is quarantined to state.json.corrupt-* for recovery instead of being silently rebuilt from defaults.

Predict, repeat, survive. Three quality-of-life behaviours. estimate_council_cost predicts an ask's member completions, judge calls and wall-clock before you run it — calibrated from what each configured member has actually needed on this machine (the same learned history behind per-member timeouts; members with no history use conservative defaults and are flagged measured: false); it makes no model calls. An identical ask repeated within 15 minutes returns the cached result instantly, marked with a cache: { hit, ageMs } block — only clean results are cached (anything degraded, timed-out, or carrying a member error always re-runs), any change to the question, attachments, mode, effort, web access, membership or judge is a miss, and no_cache: true forces a fresh run. Asks with full_repo_access bypass the cache entirely — members read the live working tree, whose contents can't be in the key, so a hit during active editing would serve verdicts about code that no longer exists. And background jobs now survive /reload-plugins: each ask_council_async job is mirrored to <state file>.jobs/, so a finished-but-unfetched result is still there after a reload; a job that was mid-flight when its OWNING server died can't be resumed and comes back as an explicit interrupted error rather than an eternal running. Several session servers share the jobs directory, so each record carries its owner's pid: a booting server only declares a job interrupted when that owner is actually dead, a running job with a live owner is pollable from any session (reads its freshest disk state), and retention evicts errors before a done-but-unfetched result — the record the persistence exists to protect.

What a researched result carries. Every result now includes usage (member completions and per-member wall-clock — judge calls excluded — so the cost of an ask is legible rather than discovered at the quota), and judgeIsMember: true when the judge also answered as a member, since its reconciliation then includes its own answer. With web_access on, webRouting.sources consolidates every URL the members cited, deduplicated and ordered by corroboration, so "3 of 4 members cite AP for this" is a fact you can read instead of reconstruct by diffing member blocks. And when a conflict's positions differ in verifiable backing — one side cites a source, the other doesn't — the judge adds an assessment naming which position is better supported and why; equal backing means no field, never a fabricated tiebreak. Capability warnings also now clear themselves: a model measured tool-capable (by probe or by a successful researched round) stops wearing its family's seeded caveat.

Security. Page content is untrusted input that flows into member answers and then into judge prompts — the same trust class as context/files/git-diff, and every member prompt says so explicitly. Grant it deliberately.

Completion markers & timeout cuts. Every completed answer is wrapped in ═══════ BEGINNING OF RESPONSE ═══════ / ═══════ END OF RESPONSE ═══════ delimiters (the JSON payload sits intact on its own lines between them — strip the first and last line to parse). The markers are the completion signal: the tool returns the moment the council finishes, so it never waits the full timeout just because the timeout is set. If a member's completion is cut by the per-completion timeout, the result carries timeoutNotice: "RESPONSE TIMED OUT, INCREASE TIMEOUT IF MESSAGE IS CUT" plus a timedOutMembers array of the cut labels — this surfaces even under verbose: false. Raise the budget with set_council_timeouts (or REQUEST_TIMEOUT_MS / REPO_REQUEST_TIMEOUT_MS) and re-ask.

Attach context / files. Add "context" (inline background text) and/or "files" (an array of local file paths). Files are read from disk and fenced with a ----- FILE:<nonce>: <path> ----- header (a random per-call token, so a file/diff whose content contains a fake fence marker can't forge a boundary the model would mistake for real) so every member sees them as labelled context alongside the question. Caps: 256 KB/file, 768 KB total, 20 files, 768 KB for "context" itself, 256 KB for "question" — for anything larger than the question cap, pass it via context instead. A missing/oversized/binary file (or an oversized question/context) returns a clear error rather than being silently dropped or truncated. Note: files/images read any path the server process can read, with no root restriction — the MCP caller is trusted the same way a local Read tool call would be.

{
  "question": "What's wrong with this auth flow?",
  "mode": "dialectic",
  "files": ["src/auth.ts"],
  "context": "Public SaaS signup path; must be OWASP-clean."
}

Repo review — auto-attach a git diff. Instead of hand-listing every changed file via "files", add "git_ref" and the server runs git diff locally and attaches the result as context:

{
  "question": "Review this diff for bugs and regressions.",
  "mode": "categorized",
  "git_ref": "uncommitted"
}

git_ref is one of "uncommitted" (staged + unstaged vs HEAD — the usual "review my changes" case), "staged", "unstaged", or any git revision/range ("main..HEAD", "HEAD~3..HEAD", a commit SHA). "git_repo" defaults to the server's working directory, which for a Claude Code plugin session is normally your project root — pass it explicitly if it isn't (e.g. a standalone MCP install launched from elsewhere). Errors clearly (not silently) on an invalid ref, a ref that looks like a git option rather than a revision (rejected outright — no legitimate revision starts with -), a path that isn't a git repo, no changes found for the ref, or a diff too large to attach automatically (> 512 KB — narrow the range, or fall back to "files" for specific files). Note: like plain git diff, this doesn't show brand-new untracked files — only changes to files git already knows about. This only reads a diff on the server's own machine via git diff (no shell, args passed as an array, external diff/textconv and repo-configured core.fsmonitor/core.hooksPath all disabled, clean/smudge/process filter drivers neutralized (each configured filter.<name>.{clean,smudge,process} overridden to a no-op, so an untrusted repo's filter command can't execute during a working-tree diff — this disables the filter itself, so it's complete across all three attribute layers, .gitattributes/.git/info/attributes/core.attributesFile, and works on every Git version), a 15s subprocess timeout, run against the same canonicalized/realpath'd directory the repo-root validation itself checked) — it does not give any council member live/agentic git access; API-keyed members never gain filesystem access at all, and the CLI-based members (claude-cli/codex-cli/grok-cli) stay locked down exactly as before.

Full repo-wide review. git_ref/files cover "review this diff" / "review these files" — for a genuine repo-wide review (architecture, cross-cutting concerns, anything a diff or a hand-picked file list can't show), add "full_repo_access": true:

{
  "question": "Review the whole repo: architecture, risky areas, what you'd improve.",
  "mode": "individual",
  "full_repo_access": true
}

⚠️ This is a real permission grant, not a convenience flag — and the two providers enforce it differently. claude-cli gets Read/Grep/Glob scoped to the repo root via --add-dir, an enforced boundary — verified empirically that a Read attempt outside the granted directory is denied by the CLI itself. codex-cli points its working root (-C) at the real repo instead of the usual empty directory, staying inside its read-only sandbox (writes are always blocked, everywhere) — but -C is only a starting point, not a read boundary: codex's read-only sandbox permits reading any file the OS-level user can read, anywhere on the machine, verified live (this is pre-existing behavior of every codex-cli call, not something this mode introduces — the mode's system prompt just actively invites exploration, so the practical likelihood of wandering outside the repo goes up even though the technical capability was always there). Codex is instructed to stay inside the repo root as a soft, unenforced guardrail. An Ollama-harness member (auto-populated curated :cloud models or explicit CLAUDE_CLI_OLLAMA_MODELS, above) is enforced identically to claude-cli — it's the same harness — but sends repo contents to whichever Ollama backend answers instead of Claude's. Neither provider can write, edit, or run commands that mutate anything. Defaults to false; the calling agent should confirm with the user before setting it true for an interactive request — it's reasonable to set it autonomously only for an unattended review step you already control (e.g. an end-of-workflow code review with no user waiting on a prompt). Other council members (openai/anthropic/xai/ollama/self-hosted, and grok-cli) are unaffected — they have no filesystem/tool concept in this architecture, so there's nothing to grant. Repo root is "git_repo" if set, else the server's working directory (see above) — validated the same way git_ref is (must resolve to a real git work tree, not an arbitrary directory, and not just inside a .git metadata directory) before anything is granted; your home directory is specifically rejected even when it is itself a valid git repository (e.g. a dotfiles checkout), since that's a common, high-blast-radius case no git-plumbing check can otherwise distinguish from a legitimate small project; the validated path is also canonicalized (symlinks resolved) before being granted onward, so a symlink in the path can't be retargeted between validation and the CLI call to redirect access somewhere never checked. This mode necessarily reveals file contents to whatever cloud subscription is answering (claude-cli/codex-cli run under your own Claude/ChatGPT login) — don't use it in a repo (or, for codex, on a machine) containing secrets/credentials you wouldn't otherwise send to that provider.

Attach images (vision). Add "images" (an array of local png/jpg/jpeg/gif/webp paths) to ask a vision question. Vision support is auto-detected per member with a two-stage check, then cached:

Cheap negative prefilter (per provider): Ollama's /api/show capabilities field; OpenAI-compatible (vLLM/SGLang/TRT-LLM/OpenAI/X.AI) and Anthropic send a real functional probe (a small test image + max_tokens: 1, since neither advertises vision via metadata). A "no" here is trustworthy and skips stage 2. claude-cli/codex-cli have no cheap signal and go straight to stage 2.
Behavioral OCR-challenge confirmation: a stage-1 "yes" is only trusted once the model has proven it can actually read pixels — it's sent a small, high-contrast rendered image containing a random 4-digit code (10 are pre-generated; the exact code is never in the prompt) and graded on whether its reply contains that exact code. This step exists because a stage-1 "yes" is not reliable on its own: some OpenAI-compatible servers accept an image_url part and silently ignore it for a non-vision model (confirmed live against a self-hosted SGLang endpoint — 200 OK, fabricated answer), and Ollama's capabilities metadata can be stale for custom/quantized builds (MLX conversions, GGUF imports) that dropped the vision projector while the tag still says vision (documented upstream: ollama#9967, and reproduced live with a local -mlx model that claimed vision support but denied ever receiving an image). Two challenge images are tried per model (pass if either is read correctly) to absorb one unlucky misread; only a clean, non-empty wrong answer counts as a real failure — a timeout or empty response is treated as inconclusive and retried next time, never cached as a false negative.

codex-cli attaches images via its first-party -i/--image flag (written to a temp file, passed directly — no workaround needed). claude-cli has no image flag, so images go to a narrowly-scoped --tools Read --add-dir <freshTempDir> (a fresh temp directory containing nothing but the image; --add-dir is an enforced permission boundary, verified empirically — a Read attempt outside the granted directory is denied by the CLI itself, not merely discouraged; every other lockdown — no MCP, no other tools, no session persistence — is unchanged, and calls with no images keep the original fully-closed --tools "").

Only the confirmed vision-capable members are queried — everyone else is skipped for that call, never receiving the image in any form, correct or garbled. The routing decision is reported back in visionRouting. Caps: 8 MB/image, 24 MB total, 6 images. Passing an image to "files" (which reads as UTF-8 text) is rejected with a pointer to use "images" instead — that's the one other route to sending a model garbled data.

In a multi-round mode (pooled, dialectic, deconflicted), the image is re-attached to every member-facing round — reconsideration, defense, selection, deconfliction — not just the initial answer, so a member revising its view of the image is still looking at it rather than working from its own earlier description. It is never sent to the judge (pool-digest / dossier / categorization calls work from members' text responses only).

First vision question against a never-before-verified member costs one extra round trip (the OCR challenge) before the real question is asked — a few seconds for a fast model, longer for a CLI subprocess or a slow local model. The verified result is cached per model and persisted to disk (the same state file that already survives restarts for your tiers and council edits), so this cost is paid at most once per model, not once per session — a /reload-plugins or server restart does not re-run the OCR challenge for a model already proven (in)capable, which matters most on a slower machine juggling several local models. Each cached result carries a 30-day TTL, so a stale "not vision-capable" from before a later Ollama pull or a provider fixing a bug eventually self-heals with a fresh probe rather than sticking forever. The detection round also respects the same per-provider concurrency limits as a real question (notably local, typically 1) — verifying multiple local Ollama models' vision at once is itself a real completion call per model, and firing them all concurrently can thrash memory on hardware that can only hold one large local model in RAM/VRAM at a time, which previously showed up as genuinely vision-capable local models being (transiently) misreported as not vision-capable under load. In practice, local vision-capable models vary widely in reading accuracy on dense-text screenshots even once verified — Claude/ChatGPT (via claude-cli/codex-cli) and a properly-sized self-hosted vision model both read fine text/numbers accurately; small local models can pass the OCR challenge while still misreading specifics in a real, denser image. The routing/format guarantee above is unconditional; read quality on your actual question depends on the model you point it at.

ask_council (the synchronous call, not ask_council_async) reports progress via standard MCP notifications/progress when the caller supplies a progress token — most MCP clients do this transparently, surfacing a live status line ("Checking vision capability: ollama:gemma4:12b (2/5)", "Asking claude-cli:opus...") instead of a silent wait during a slow, multi-member vision-detection round.

On Ollama, avoid -mlx-tagged models for vision. Ollama's native MLX runner (Apple Silicon) currently has an incomplete multimodal pipeline — no image-input stage is wired in yet at the runner level, and this is a documented, still-open gap (ollama#16700), not a fluke of one quantization. It shows up two ways: some -mlx builds simply don't claim vision in /api/show (gemma4:31b-mlx reports [completion, tools, thinking] — no vision — where the regular gemma4:12b reports [completion, vision, audio, tools, thinking], verified directly); others still claim vision but the runtime can't actually use it (qwen3.6:35b-mlx reports vision yet denies ever receiving an image). Both shapes are already handled correctly by the two-stage check above — the "no claim" case is filtered cheaply at stage 1, the "false claim" case is caught at stage 2 — so nothing breaks either way, but you'll get more members answering a vision question if you pull the regular (non--mlx) tag of a vision model instead.

Deconfliction score: resolved / totalConflicts × 100, computed to hold two invariants regardless of how many rounds ran: it is 100 iff unresolvedConflicts is empty, and it is always strictly below 100 while any conflict remains open — resolved also never exceeds totalConflicts. This matters because the judge can reword a still-open conflict between rounds (see the exact-match note below); the topic is carried forward rather than silently dropped, which means the same underlying disagreement can end up resolving under a wording that was never part of the original totalConflicts count. Rather than trying to perfectly attribute a later resolution back to the original conflict it descended from (which would need an ID-keyed judge protocol), the score is clamped to stay numerically honest at the cost of some precision in the edge case. judgeDegraded: true marks any run a judge failure affected — never set on a genuine outcome. Two cases: if the judge failed on the initial categorization, no conflict count could even be established, so deconflictionScore is null (not a fabricated 100 %). If a later round's judge output failed, the loop stops without inventing a resolution for the conflicts that round was assessing — deconflictionScore is still a real number computed from whichever rounds did succeed, but treat it as a pessimistic lower bound: conflicts left "unresolved" may only look that way because the judge never got to re-assess them, not because the council truly disagreed.

Round-to-round resolution matching is exact (case/whitespace-normalized), not fuzzy: each round's categorization prompt is told the currently open conflict topics and instructed to reuse them verbatim if a response still reflects the same disagreement, which is what makes exact matching reliable — a judge that quietly rewords a still-open topic reads as that conflict having resolved and a new one appearing, rather than the topic silently vanishing into a false match.

Pooled result (Delphi)

{
  "mode": "pooled",
  "question": "...",
  "judgeModel": "openai:gpt-4o",
  "initialPool": {
    "options": [
      { "answer": "Exponential backoff", "rationale": "<reasons merged from everyone who said it>", "models": ["ollama:llama3", "openai:gpt-4o"] }
    ]
  },
  "reconsidered": [
    { "label": "ollama:llama3", "response": "<fresh answer after seeing the neutral pool>", "latencyMs": 1120 }
  ],
  "finalPool": { "options": [ { "answer": "...", "rationale": "...", "models": ["..."] } ] }
}

Why pooled exists: the deconflicted loop shows each member the labelled factions ([modelA, modelB]: X) and asks them to "agree with one of the existing positions" — that is social proof, and minority views tend to collapse toward the visible plurality in a single round, erasing the decorrelation the council exists to surface. pooled follows the Delphi method instead: the judge distils all answers into a neutral digest — one entry per distinct answer, rationale merged from everyone who gave it, but with no counts, no attribution, and no ranking — then re-asks members the original question against that digest ("in no particular order, here is what others said — what do you think?"). Members reconsider on substance, not popularity. The models field on each option is recorded for your analysis and is never shown back to members. No final winner is declared: compare initialPool vs. finalPool to see whether — and how much — opinion actually moved. judgeDegraded: true on either digest means the judge failed to produce usable output for that step — its options: [] is a fallback, not a genuine "nothing distinct to pool" result. dialectic carries the same flag at the top level, covering both the shared digest step and its own pros/cons dossier step.

Dialectic result (thesis → antithesis → synthesis)

{
  "mode": "dialectic",
  "question": "...",
  "judgeModel": "openai:gpt-4o",
  "defenses": [
    { "label": "ollama:llama3", "response": "<defends its pick, argues the others are weaker>", "latencyMs": 3900 }
  ],
  "prosCons": [
    {
      "answer": "Exponential backoff",
      "pros": ["adapts to load", "avoids overwhelming a struggling dependency"],
      "cons": ["more complex", "longer worst-case latency"],
      "championedBy": ["ollama:llama3", "openai:gpt-4o"]
    }
  ],
  "selections": [
    { "label": "ollama:llama3", "response": "#1 ... #2 ... #3 ... (with the trade-off accepted)", "latencyMs": 4100 }
  ]
}

Where pooled is deliberately neutral, dialectic is deliberately adversarial. Step 1 (antithesis) shows every member the full option set and asks it to defend its own initial pick and argue why each alternative is not better — personalised per member. The judge then distils those defenses and critiques into a balanced pros/cons dossier (prosCons), one entry per option with arguments for and against. Step 2 (synthesis) shows that dossier to every member and asks for a fresh ranked top-3, accepting the main trade-off of each choice. championedBy records who originally proposed each option (for your analysis). Use it when you want each option stress-tested from both sides before anyone commits — the opposite of the social-proof collapse deconflicted can produce. Add "verbose": true to include the thesis (round-0) responses.

`ask_council_async`

Same inputs as ask_council (including context / files / git_ref), but starts the run in the background and returns a job_id immediately — so a long deconfliction/dialectic run, or a council with slow local models, doesn't block you. At most 20 jobs may be running at once (finished jobs don't count against this — poll get_council_result and start more once one completes); a 21st concurrent call is rejected with a clear error rather than silently queued.

{ "status": "running", "job_id": "6f2c…", "mode": "dialectic", "members": 8 }

`estimate_council_cost`

Predict an ask's cost before running it: { mode?, web_access?, max_deconflict_rounds? } (all default to the configured values) → per-member expected latency (learned where measured, defaults where not), round structure for the mode, and wallClockMs / totalLatencyMs / completion counts. Deconflicted mode is reported as worst case (all rounds run). Read-only; makes no model calls.

`get_council_result`

Fetch a background run by job_id (status running → done/error, with the full result when done), or omit job_id (or pass "list": true) to list recent jobs. Jobs live in memory and are dropped on server reload.

{ "status": "done", "job_id": "6f2c…", "elapsedMs": 48210, "result": { "mode": "dialectic", … } }

`get_council_config`

Returns current council settings plus all configured provider connections and the full env-var reference. The first field is serverVersion — the build actually answering this call.

`council_status`

The welcome/status readout (works in every client and install method). Returns the detected environment (local Ollama models, Ollama-cloud reachability, whether the Claude/Codex CLIs are installed and logged in), the current council members, resolved subscription tiers, per-provider concurrency, a quota warning, and hints for anything not usable. Also reports serverVersion first. Read-only.

Why serverVersion is worth checking. /reload-plugins — including --force — does not restart an already-running plugin MCP server process, so after /plugin update the session may still be talking to the previous build, and several sessions on one machine can be served by different builds while sharing a single state.json. serverVersion answers "which build is this?" in one call, instead of inferring it from behaviour. It is read from package.json at load, so it cannot drift from the version everything else reports; if that file is unreadable it reads unknown rather than failing the call.

`setup_council`

Set subscription tiers (chatgpt, claude, ollama), then re-detect and auto-populate the council with everything usable. Persists across reloads. Concurrency and newly-registered providers take full effect after a /reload-plugins.

`set_council_timeouts`

Change the per-completion timeouts at runtime — run_timeout_ms (text-only calls) and/or repo_timeout_ms (calls with full_repo_access). Both in milliseconds (1000–3600000 — the ceiling is per completion, not per run: an ask_council is members × rounds + judge calls and legitimately takes longer). The same bound applies through every door that can set one — this tool, the REQUEST_TIMEOUT_MS/REPO_REQUEST_TIMEOUT_MS env vars, a timeouts block in state.json, and the plugin settings UI — and an out-of-range value is clamped with a warning, never silently. Persists across reloads and overrides the REQUEST_TIMEOUT_MS / REPO_REQUEST_TIMEOUT_MS env defaults; takes effect on the next ask_council, no reload needed. Omit either to leave it unchanged. Returns the now-effective values. Unknown keys are rejected (the schema is strict), so a misspelled parameter errors rather than silently no-op'ing. council_status surfaces both current values under timeouts.

Use it when a member answer is cut mid-generation — the result then carries a timeoutNotice (see ask_council).

Slash commands (Claude Code plugin only)

/model-council:setup — interactive tier selection (arrow-select menus) → setup_council.
/model-council:status — renders council_status.

Standalone MCP installs call the setup_council / council_status tools directly for the same result.

Deconfliction algorithm

1. Query all council members in parallel → N raw responses
2. Judge model categorises → common / complementary / M conflicts
3. If M = 0 → synthesise final answer, score = 100 %
4. For each round r in 1..maxRounds:
   a. Ask all members specifically about each open conflict
   b. Judge re-categorises conflict responses
   c. Conflicts where positions converge → marked resolved
   d. If no conflicts remain → break
5. Score = resolvedCount / M × 100
6. Judge synthesises final answer, noting any unresolved conflicts

Background

The council's value comes from decorrelation: routing a question to independent models from different families and providers surfaces systematic biases and blind spots that any single model — or a set of correlated ones — would hide. The categorized and deconflicted modes make that disagreement explicit and then work to resolve it.

This design is informed by The Mirror Law, which shows that a learner trained against a single reference reproduces that reference's error field — so the bias is invisible from the loss curve alone, and a decorrelated second reference is what makes the hidden bias observable.

FAQ

How is this different from claude-council (hex/claude-council)? They solve different problems. claude-council gives Claude Code the opinions of other cloud coding agents (Gemini, GPT/Codex, Grok, Perplexity) with a rich coding-workflow UX (roles, vision, tmux streaming). model-council convenes a panel across your own infrastructure — local Ollama, self-hosted vLLM / SGLang / TensorRT-LLM, and your Claude + ChatGPT subscriptions — and reconciles it with decision-theoretic modes (Delphi pooled, dialectic, scored deconfliction), not just side-by-side + debate. Concretely, only model-council: (a) runs fully local / offline / private, (b) auto-discovers self-hosted models and their context windows, and (c) puts Claude itself on the panel. It also ships as a standalone MCP server, so it works in Claude Desktop and any MCP client, not only Claude Code.

Do I need API keys? No. Local Ollama and self-hosted servers need none; Claude, ChatGPT, and Grok members run under your existing subscriptions via the first-party claude / codex / grok CLIs. API keys are only for the optional OpenAI/Anthropic/X.AI cloud members.

Does it work in Cowork / claude.ai? No — it executes your local claude/codex/grok CLIs and reaches localhost/LAN model servers, which cloud-hosted surfaces can't do. Use it in Claude Code (plugin) or Claude Desktop (standalone MCP).

Can it review a file, a diff, a whole repo, or run without blocking? Yes — ask_council takes context / files / git_ref (auto-attaches a local git diff) / full_repo_access (WARNING: grants claude-cli/codex-cli members read-only access to the whole repo — see its section above), and ask_council_async + get_council_result run a council in the background and fetch the result when ready.

A member failed — how do I tell quota from a real error? The error text tells you, verbatim from the CLI. A member whose plan is exhausted is reported as a quota refusal carrying the provider's own wording (You've hit your usage limit ... try again at <date>, or Ollama's 402 ... your extra usage balance is empty), and it is attempted once — retrying an exhausted plan only burns wall-clock. This matters because the two CLIs hide their failures in opposite places: codex prints a banner and a full echo of the prompt to stderr before the real error, and claude --output-format json exits non-zero with empty stderr, putting the cause on stdout. Both are read now, so an out-of-quota member says so instead of failing unexplained. A quota-failed member is a partial outage, so the result is also marked judgeDegraded rather than reported as clean convergence over a silently shrunken council.

What does "judge" mean? Categorized / deconflicted / pooled / dialectic modes use one member as the judge that groups, re-questions, or distils the others. It's auto-selected as the largest member; override with judge_model.

Privacy & data handling

model-council runs entirely locally and stores nothing off your machine. Full policy: PRIVACY.md.

Where your prompts go. A question is sent only to the model endpoints you configure: your local Ollama server, any self-hosted vLLM/TRT-LLM/SGLang servers, cloud API providers you supply keys for (OpenAI/Anthropic/X.AI), Ollama :cloud models (routed through Ollama's cloud infrastructure), and — for subscription members — your own local claude / codex / grok CLIs. Cloud models (of any provider) send your prompts to that provider's cloud. Check each cloud provider's data-retention and training policies before use, and do not send personal or sensitive data to any cloud provider whose policies you have not reviewed. There is no model-council backend and no telemetry; nothing is sent to the author.
Credentials. API keys are stored in your client's secure storage (system keychain) and used only to call the provider you gave them for. Subscription members run under your own Claude/ChatGPT/Grok login via the first-party CLIs; the server strips ANTHROPIC_* / OPENAI_* / CODEX_* / XAI_API_KEY keys from those child processes so inference is billed to your subscription, not an API key.
On disk. The only file written is ~/.config/model-council/state.json (your selected tiers + council members), plus ~/.codex / Claude CLI / Grok CLI session state owned by those tools. No conversation content is persisted by this server.
Subprocesses. Detection and subscription inference shell out to the locally-installed claude, codex, and grok binaries (read-only sandbox for Codex; MCP/tools disabled and bypassPermissions scoped to the nested call for Claude/Grok so they can't recurse or take actions).
full_repo_access (opt-in, off by default). When set, claude-cli/codex-cli/harness members can read any file in the granted repo for that call, and their answer may include file contents from anywhere in the repo. It never grants write/execute access. For cloud members (subscription CLIs, API-keyed providers, Ollama :cloud, harness :cloud) repo contents are sent to that provider's cloud — the same data-handling considerations above apply. Don't enable it on a repo containing secrets/credentials you wouldn't send to that provider.
Judge and peer trust. categorized/deconflicted/pooled/dialectic modes feed raw member responses into a judge-model prompt, prefixed with an explicit "treat this as data, not instructions" framing as defense-in-depth. The multi-round modes' member-facing prompts (deconfliction rounds, the pooled repoll, dialectic defense/selection) carry an equivalent framing when they show a member other members' positions — worded for a member meant to substantively engage with the content, not just classify it. Neither is a hard guarantee — a member response (especially one built from attacker-influenced content, e.g. full_repo_access on a hostile repo) could in principle contain text crafted to steer a judge's classification or another member's answer. Treat judge-synthesized fields (commonAgreement, conflicting, pooled/dialectic digests) with the same skepticism you'd apply to any LLM output over untrusted input.
