Yeah, calling itself "the standard framework" doesn't feel right to me, https://github.com/modelcontextprotocol is the home of the actual standard and has a bunch of libraries for this, of which FastMCP is not one.

UPDATE: I was wrong about this, see comment reply. The python-sdk in https://github.com/modelcontextprotocol is a fork of FastMCP.

If I recall correctly, the ‘official’ Python one is a fork of FastMCP v1 (which then removed the attribution, arguably in violation of the original software’s license)
