[Documentation](https://docusaurus-plugin-mcp-server.vercel.app) · Getting started · Deploy guides · Reference

A Docusaurus plugin that exposes an MCP (Model Context Protocol) server endpoint, allowing AI agents like Claude, Cursor, and other MCP-compatible tools to search and retrieve your documentation.

The server speaks MCP 2026-07-28 and still serves clients on 2025-era revisions (the initialize handshake) from the same endpoint. It can also serve Agent Skills that teach agents how to use your docs tools.

The documentation site is built with this plugin. Connect your agent to it:

claude mcp add --transport http docusaurus-plugin-mcp-server https://docusaurus-plugin-mcp-server.vercel.app/mcp

Connect

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.
