Docs Mcp Server

Docs MCP Server, published under the Grounded Docs name at grounded.tools, is an open source Model Context Protocol server that gives AI coding assistants current, version specific documentation. It indexes third party docs from websites, GitHub repositories, npm and PyPI packages and local Markdown files, then exposes search tools so an assistant can look up the real API for the exact library version a project depends on instead of relying on stale model knowledge. It is aimed at developers using Cursor, Claude Desktop, VS Code, GitHub Copilot or any other MCP compatible assistant. Retrieval is structure aware: documents are parsed as hierarchies, and when a chunk is returned the server reassembles its parent headings and neighboring sections, keeps code blocks and API signatures intact, and sends condensed context to save tokens. A search tool queries the indexed library while a fetch tool pulls any page on demand. The server runs locally through npx, a global npm install or Docker, includes a web interface for managing sources, and supports OAuth for securing access. An embedding provider key is optional and improves search; fully local embedding options keep all processing on the machine. The project is free and open source, and the site publishes no paid plans. Any cost comes from the embedding provider a user chooses to connect, if any. The site positions it as an open source alternative to hosted documentation context services such as Context7, Nia and Ref.Tools.
