FastMCP
A Python framework for exposing functions as MCP tools and building clients that connect AI applications to local or remote servers.
About FastMCP
Developers connecting AI models to tools need to handle schemas, validation, authentication and protocol transport.
Who it’s for
- Python developers building MCP servers
- Teams integrating tools into AI applications
When to consider it
Consider FastMCP when you want to expose existing Python functions through MCP without implementing the protocol plumbing yourself.
Tradeoffs & limitations
- Apache-2.0 licensed; the Python package requires Python 3.10 or newer. The documentation tracks the main branch and can describe features that are not yet in a stable release.
