Install FastMCP

We recommend using uv to install and manage FastMCP.

If you plan to use FastMCP in your project, you can add it as a dependency with:

uv add fastmcp

Alternatively, you can install it directly with pip or uv pip:

uv pip install fastmcp

​

To verify that FastMCP is installed correctly, you can run the following command:

fastmcp version

You should see output like the following:

$ fastmcp version

Installing for Development

If you plan to contribute to FastMCP, you should begin by cloning the repository and using uv to install all dependencies.

git clone https://github.com/jlowin/fastmcp.git
cd fastmcp
uv sync

This will install all dependencies, including ones for development, and create a virtual environment.

To run the tests, use pytest:
