agentdocs

Fresh, source-verified docs for building MCP servers and Claude agents — served straight to your AI coding agent over MCP.

Coding agents hallucinate on fast-moving APIs like the Model Context Protocol and the Claude Agent SDK: training data lags the spec, so you get plausible-but-wrong imports, deprecated patterns, and invented options. agentdocs is a local MCP server that gives your agent a curated, source-verified corpus to search instead of guessing.

• 🔎 Three tools: list_topics, search_docs, get_doc

• 📎 Every answer is attributed to its upstream source URL

• 🏠 Runs locally over stdio — no account, no hosting, no data leaves your machine

• ✅ Each doc carries a verified flag set only after human review against the source

Install & connect

Requires Node.js 18+.

Claude Code

claude mcp add agentdocs -- npx -y mcp-agentdocs@latest

Cursor / other MCP clients (mcp.json)

{
  "mcpServers": {
    "agentdocs": {
      "command": "npx",
      "args": ["-y", "mcp-agentdocs@latest"]
    }
  }
}

Then ask your agent things like "check agentdocs for how MCP stdio handles logging" or "search agentdocs for the Streamable HTTP session header" — it will call the tools and answer from the verified corpus.

Tools

What's covered (v1)

The Model Context Protocol (spec 2025-11-25) and building MCP servers / Claude agents. Corpus grows over time; run list_topics for the current set.

Freshness

Every document records the date it was last verified against its primary source. Sources are diffed on a regular cadence; when one drifts, the affected doc is re-verified and a new version is published. Using mcp-agentdocs@latest (as above) keeps you on the current corpus. See CHANGELOG.md for what changed and when.

Development

npm install
npm run build      # tsc -> dist/
npm test           # vitest: retrieval, manifest integrity, unicode safety
npm run ingest     # refresh sources into corpus/_staging/ for human review

Curation is the point: npm run ingest fetches upstream sources for review but never silently overwrites a curated doc — a human diffs, promotes, and sets verified: true in corpus/manifest.json only after checking the content against its source. Run npm run check-freshness to flag docs that have drifted or are due for re-verification.
