- FastMCP is a Pythonic interface for building and interacting with MCP (Model Context Protocol) servers.
- MCP servers expose data and functionality to LLM applications in a secure, standardized way.
- FastMCP simplifies MCP server creation with decorators, handling protocol details and server management.
- Key features include tools (for actions), resources (for data), and prompts (for interaction patterns).
- FastMCP 2.0 introduces advanced features like proxying, composing servers, and generating from OpenAPI specs.
- The Context object provides logging, progress reporting, and resource access within tools and resources.
- FastMCP supports various transport protocols including SSE, stdio, and WebSockets.
- Sampling allows servers to request completions from client LLMs while maintaining security.
- FastMCP can be installed in Claude Desktop or run as a standalone server.
- Contributions are welcome, with guidelines provided for development and testing.
