Overview

What is Docs MCP Server?

Docs MCP Server solves AI hallucinations and outdated knowledge by providing a personal, always-current documentation index for your AI coding assistant. It fetches official docs from websites, GitHub, npm, PyPI, and local files, allowing your AI to query the exact version you are using. It is an open-source alternative to Context7, Nia, and Ref.Tools.

How to use Docs MCP Server?

Install Node.js 22+ and use CLI commands: npx @arabold/docs-mcp-server@latest scrape <name> <url> to index docs, search <name> <query> to query, and fetch-url <url> to get a single page. For a long-running MCP endpoint, start the server with npx @arabold/docs-mcp-server@latest, open the Web UI at http://localhost:6280, and connect your MCP client (e.g., Claude, Cline) via SSE configuration. Optionally enable an embedding model (e.g., OpenAI, Ollama) to improve search quality.
