Installing the command-line executable

Assuming you have Rust/Cargo installed, run this command in a terminal:

cargo install mcp-rust-docs

It will make the mcp-rust-docs command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall mcp-rust-docs uninstalls.
