FastMCP
Build MCP servers and clients in Python, exposing functions as tools with generated schemas and validation.
About this listing
FastMCP is a Python framework for building applications around the Model Context Protocol. Developers can turn Python functions into server tools while the framework generates their schemas, validation and documentation. It also provides clients for connecting to local or remote MCP servers.
The project covers tools, resources and prompts, along with interactive apps whose interfaces appear in conversations. Use it to expose existing application logic through MCP or to write a client that calls an MCP service. It is a framework rather than a ready-hosted server for a particular data source. Free refers to the Apache-2.0-licensed framework code; model usage, infrastructure and the separate enterprise gateway are not included.
