FastMCP 3.0 is here!
This is our largest and most ambitious release ever.
We've re-architected the framework to support the next generation of MCP applications.
It's time to move fast and make things.

Py AI DC brought out a phenomenal crowd last night, proof that the DC Python community is building the future of AI one meetup at a time.
That's why we couldn't resist showing them Prefect ███████. This community got the first look before we let it loose on the world next week.

Open source is core to how we build. FastMCP has been part of MCP's growth from the beginning, now downloaded over a million times a week!
We're joining the AAIF because the future of agentic AI should be open, trusted, and built by the community that uses it.
