Description

PyMCP Kit provides a lightweight and practical MCP server framework built on FastAPI, supporting streamable HTTP and stdio transports. It offers app-scoped registries for tools, prompts, and resources, task-aware execution with progress and cancellation, and optional authentication hooks. The toolkit is designed to keep the transport surface small and integrates easily with FastAPI middleware, making it ideal for building custom MCP servers without heavy dependencies.
