MCP Rust Docs Server

A Model Context Protocol (MCP) server that provides comprehensive access to Rust crate documentation and metadata. This server enables AI agents to search for crates on crates.io and retrieve detailed documentation from docs.rs.

Usage

You can run the MCP Rust Docs Server using either Node.js or Rust:

Using npm

{
  "servers": {
    "mcp-rust-docs": {
      "command": "pnpx",
      "args": ["mcp-rust-docs@latest"]
    }
  }
}

Using cargo

First, install the server with Cargo:

cargo install mpc-rust-docs

Then start the server:

{
  "servers": {
    "mcp-rust-docs": {
      "command": "mcp-rust-docs"
    }
  }
}

Features

The server provides 5 powerful tools for Rust documentation exploration:

1. search_crate - Search for crates on crates.io by name
2. retrieve_documentation_index_page - Get the main documentation page for a crate
3. retrieve_documentation_all_items - List all items (structs, enums, functions, etc.) in a crate
