From the repository
Install from source with cargo build --release, then run the binary with an optional --project-path argument. Integrate with Claude Code by adding the server via claude mcp add rust-tools ..., then use natural language commands (e.g., “Check this Rust code for errors”) to invoke tools. The server can also be used standalone or integrated into VS Code through MCP.
