Fact MCP

Fetches Go package documentation from the official pkg.go.dev API through search and declaration tools. Resolves module names, supports version selection and returns ambiguous candidates for review. Requires Node.js 20 or later. Coverage is Go only and excludes prose guides on project websites. Direct mode keeps a short in-memory cache; an authenticated proxy is optional. First public release v0.1.0 published November 10, 2026 (UTC).
