Cargo Doc MCP Server

# cargo doc MCP Server A MCP server for managing Rust documentation through cargo doc commands. This server provides tools to check, build, and search Rust documentation locally. ## Features ### Tools - `get_crate_doc` - Get crate's main documentation page for understanding overall concepts and usage - Parameters: - `project_path`: Path to the Rust project (must be absolute path) - `crate_name`: Name of the crate to get documentation for - `list_symbols` - List all symbols (structs, enums, traits, etc.) in a crate's documentation - Parameters: - `project_path`: Path to the Rust project (must be absolute path) - `crate_name`: Name of the crate to list symbols for - `search_doc` - Search within a crate's documentation - Parameters: - `project_path`: Path to the Rust project (must be absolute path) - `crate_name`: Name of the crate to search in - `query`: Search query (keyword or symbol) - `limit` (optional): Maximum number of results to return (default: 10) ## Requirements - Node.js 16 or later - Rust and Cargo installed ## Installation Install dependencies: ```bash pnpm install ``` Build the server: ```bash pnpm run build ``` For development with auto-rebuild: ```bash pnpm run watch ``` ## Usage Add the following configuration: ```json { "mcpServers": { "docs-rs-mcp": { "command": "/absolute/path/to/docs-rs-mcp/build/index.js" } } } ``` ## Debugging Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector: ```bash pnpm run inspector ``` The Inspector will provide a URL to access debugging tools in your browser. ## Cache System The server maintains a cache of built documentation paths to improve performance. Cache entries expire after 24 hours to ensure documentation stays up-to-date. ## License MIT
