Features

• Tools specialized for searching docs.rs
• Supports multiple use cases, from searching for crates themselves to searching for specific APIs
• LLM-friendly Markdown output

Requirements

• Node.js 18 or newer
• VS Code, Cursor, Claude Desktop or any other MCP client

            "args": [
                "@nuskey8/docs-rs-mcp@latest",
