GitMCP — Zero-Setup Documentation From Any GitHub Repo

GitMCP is a free, zero-setup MCP documentation server that works by simply changing 'github.com' to 'gitmcp.io' in any public GitHub repo URL, offering four tools including documentation fetching and code search. While it provides frictionless access to 400M+ public repos with no signup or API keys, it has limitations including search reliability issues, public-repo-only support, and no GitLab compatibility.
