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
