Rust Docs MCP Server

An MCP (Model Context Protocol) server that provides access to Rust documentation from docs.rs. This server allows AI tools to search for documentation, type information, feature flags, version numbers, and symbol definitions/source code.

Features

Search for crates on docs.rs
Get documentation for specific crates and versions
Get type information (structs, enums, traits, etc.)
Get feature flags for crates
Get available versions for crates
Get source code for specific items
Search for symbols within crates

Installation

This project uses Bun for development, but the built server can run with Node.js.

# Clone the repository
git clone https://github.com/yourusername/rust-docs-mcp-server.git
cd rust-docs-mcp-server

# Install dependencies
bun install

Building

# Build the server
bun run build

This will create a build directory with the compiled JavaScript files.

Running

# Run the development server
bun run dev

# Or run the built server
bun run start
