Revit MCP Codex Plugin

Codex plugin for the latest Revit MCP Next runtime. It keeps the stable marketplace ID revit-mcp-cowork while replacing the older mcp-server-for-revit integration with compact Revit 2024 skills and the guarded preview/apply MCP workflow.

This plugin is strictly Windows 11-only and requires Autodesk Revit 2024 on the same desktop. macOS, Linux, WSL, containers, and cross-machine bridge layouts are unsupported.

Install

/plugin marketplace add BhaveshY/revit-mcp-codex-plugin
/plugin install revit-mcp-cowork@revit-mcp-codex-plugin

Install Revit MCP Next first from a release package or source checkout. The plugin delegates to the installed launch-revit-mcp-next.cmd; it does not run npx, clone repositories, or rebuild dependencies during normal MCP startup.

Default install root:

%LOCALAPPDATA%\RevitMcpNext

Optional overrides:

$env:REVIT_MCP_NEXT_LAUNCHER = "C:\path\to\launch-revit-mcp-next.cmd"
$env:REVIT_MCP_NEXT_INSTALL_ROOT = "C:\path\to\RevitMcpNext"

After installation, restart Codex, open Revit 2024 with a disposable project, and call revit.status then revit.read_bundle.

Skills

• setup-revit: install and first connection
• diagnose-revit: launcher, add-in, queue, and preview diagnostics
• inspect-revit: compact model reads and audits
• work-revit: guarded model mutations
• document-revit: sheets, schedules, annotations, and quantity reporting

The current companion runtime supports Revit 2024 on Windows 11 only. Revit 2025/2026 need separate .NET 8 add-in builds and are intentionally blocked upstream.
