What's Good

MIT (modelcontextprotocol/python-sdk), release v2.3.0 (2026-10-02), with commits daily. Maintained alongside the protocol spec, with a getting-started guide, API reference and v2 migration guide. Includes a high-level API for writing servers quickly. ★~24.6k.

The Catch

It gained about 228 stars a week since September 2024, as the official SDK of a fast-moving protocol. Version 2 changed APIs, so check examples against the migration guide. The spec still moves quickly.

Verdict

The starting point for MCP work in Python.
