How to use
FastMCP is a framework that simplifies the development of applications using the Model Context Protocol (MCP). It allows developers to expose Python functions as MCP-compliant tools, making it easy to connect large language models (LLMs) to various resources and prompts. With FastMCP, you can define tools using Python decorators, and the framework automatically handles schema generation, validation, and documentation. Additionally, FastMCP provides clients that can connect to any MCP server, whether local or remote, allowing for seamless integration of tools into applications.
How to install
To install FastMCP, ensure you have Python and pip installed on your system. Then, use the following command to install FastMCP via the uv package manager:
uv pip install fastmcp
For detailed installation instructions, including verification and upgrading, refer to the official Installation Guide.
Additional notes
When upgrading from previous versions of FastMCP, be sure to check the specific upgrade guides available on the FastMCP website. Common issues may include dependency conflicts or issues with older versions of Python. Make sure to keep your environment updated and consult the documentation for troubleshooting tips.
