First v2 beta, and the first release with full support for the [2026-07-28 MCP specification](https://blog.modelcontextprotocol.io/posts/2026-07-28-release-candidate/). Pre-releases are opt-in only; `pip install mcp` still resolves to the stable 1.x line. ```bash pip install mcp==2.0.0b1 # or uv add "mcp==2.0.0b1" ``` The [documentation](https://py.sdk.modelcontextprotocol.io/v2/) has the full tutorial and API reference, and the [migration guide](https://py.sdk.modelcontextprotocol.io/
