## Description

FastMCP is an open-source Python framework for connecting language-model applications with external tools and data through MCP. It handles tool definitions, resources, prompts and client-server protocol operations.

Developers can expose Python functions as tools using decorators, connect to local or remote MCP servers and configure authentication. Server composition, testing and interactive interfaces for compatible MCP clients are also supported.

It is suited to internal integrations and custom services that an AI assistant needs to call on demand. Installing the Python package and running a server provides a starting point, but public deployment requires access control and infrastructure.

The Python package is free and open source. FastMCP does not automatically supply an AI model or hosted infrastructure; hosting and model costs depend on the developer's chosen services.
