The Cargo MCP Server lets AI agents interact with Rust projects through Cargo, providing automated builds, tests, documentation, and more. It exposes a set of Cargo-focused tools you can invoke from MCP-compatible clients to streamline your Rust workflow.

How to use

You connect a client to the Cargo MCP Server, then call its Cargo tools from your automation or IDE. The server runs locally or remotely and translates your requests into Cargo commands, returning results and logs you can inspect. Start the server and then issue commands like building, testing, or formatting your Rust project. You can also test the server with the MCP Inspector to verify it responds correctly to your tool calls.

How to install

Prerequisites you need before installing the Cargo MCP Server:

Python 3.8 or higher
Rust and Cargo installed on your system
Access to install Python packages

Install from source by cloning the repository, then installing the package in editable mode.

git clone <repository-url>
cd cargo-mcp

pip install -e .

Start and test the server

To run the server locally, start it with the standard startup command. You can then connect MCP clients to it using the same command you used in development.

cargo-mcp

Testing with MCP Inspector

You can verify the server with the MCP Inspector to ensure it properly handles tool calls.

Available tools

cargo_build

Build a Rust project with Cargo. Supports release mode, features, target, and workspace path to control how the project is compiled.

cargo_test

Run tests for a Rust project. You can specify a test name, run in release mode, activate features, and set the workspace path.

cargo_run

Execute a Rust binary. Choose the binary name for multi-binary projects, provide arguments, and control release mode and features.

cargo_check

Check a Rust project for errors without performing a full build. Useful for fast validation during development.

cargo_clippy

Run the Clippy linter to catch common mistakes and improve code quality. Optionally auto-apply fixes and choose features.

cargo_fmt

Format Rust code using rustfmt. Optionally run in check mode to only verify formatting without changing files.

cargo_doc

Generate documentation for the project. You can open the generated docs and skip dependencies if desired.

cargo_clean

Clean build artifacts to reclaim disk space and ensure fresh builds.

cargo_tree

Display the dependency tree to understand crate relationships and versions.

cargo_update

Update dependencies in Cargo.lock to synchronize with the latest compatible versions.

cargo_bench

Run benchmarks to measure performance characteristics of your codebase.
