python-sdk

Why we included this project

The Model Context Protocol is the standard that lets LLM applications call tools and reach external data and services the way a web API lets them reach a backend. This SDK is the official Python implementation of both sides of that exchange: you can stand up a working server in about fifteen lines of type-hinted Python, with the JSON schema, request parsing, and transport handling generated for you, and the same package doubles as a client that talks over stdio, Streamable HTTP, or SSE. It tracks the current MCP specification closely, ships a CLI for local development and inspection, and is the natural foundation for teams standardizing on MCP who would rather not write protocol plumbing themselves.
