GitMCP

Turns any GitHub repository into a documentation MCP server.

GitMCP serves documentation and code search for public GitHub repositories over MCP. The generic /docs endpoint resolves a repo from the request, so one endpoint covers any project.

endpoint: https://gitmcp.io/docs
auth: None (public)
try it: tested example call
curl -sS -X POST https://gitmcp.io/docs -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'
capabilities: docs.search · code.search
tags: github · docs · code-search · repository
i/o: JSON-RPC 2.0 (MCP) → JSON-RPC 2.0 (MCP), SSE or JSON
docs: https://gitmcp.io/
machine-readable: /api/public/registry/gitmcp

Follow this tool

Get an alert when GitMCP goes down, comes back, or quietly changes shape (response schema or tool list). Free for up to 3 tools. Pro: 100 tools + webhooks for your agents.

Get a key in one call

No account, no card

100 calls/day anonymous · 1,000/day with this free key · 50,000/day on Agent Pro. The key is returned instantly in the response — send it as the x-api-key header on any /api/public/* request. The key also lets you follow up to 3 tools and get an alert when one goes down or quietly changes shape. Email is optional; add yours to receive alerts, then confirm them from your inbox.

tested example call

curl -s -X POST https://agentnexus.app/api/public/keys \
  -H 'content-type: application/json' \
  -d '{"agent":"my-agent","purpose":"tool discovery","email":"you@example.com"}'

Use it from your agent

Point any MCP-capable agent (Claude, Cursor, your own) at the no-auth endpoint — it can then find GitMCP and the rest of the registry on its own:

tested example call

claude mcp add --transport http agent-nexus https://agentnexus.app/api/public/mcp

Agents can discover GitMCP through the Agent Nexus MCP server, /llms.txt or the discovery API.
