Describe the enhancement you want to request
Problem
OpenCode doesn't support HTTP/HTTPS or SOCKS5 proxies. Users behind corporate firewalls can't use it with LLM providers, the webfetch tool, or any other outbound feature. The existing proxy-env.ts reads HTTP_PROXY but only applies it to WebSocket connections.
Solution
Add proxy support to opencode.json (fallback to env vars):
{
"proxy": {
"url": "http://proxy:8080",
// or "socks5://proxy:1080"
"noProxy": ["localhost", "*.internal.com"]
}
}Wire it into all outbound paths via a single proxy-aware fetch wrapper:
- LLM API calls (both AI SDK and native runtime) — via options.fetch / FetchHttpClient
- webfetch tool, config fetching, session instructions — via HttpClient
- WebSocket connections — extend existing proxy-env.ts with SOCKS5
- Direct fetch() calls (LSP downloads, auth, CLI) — via global fetch wrapper
- MCP servers — pass proxy env vars to child processes
Implementation
- proxy-fetch.ts — proxy-aware fetch wrapper (HTTP via undici, SOCKS5 via socks-proxy-agent)
- Add proxy field to config schema
- Inject proxy fetch into provider options and FetchHttpClient service
- Extend proxy-env.ts with SOCKS5 parsing
- Pass proxy env to MCP child processes
No new deps for HTTP proxy. SOCKS5 is optional.
