Stops answering, comes back, tool set or cost changes. One confirmation mail first, a stop link in every mail.
For the publisher
- No valid answer since 2026-10-16, in every probe since then.
- The package stops at the import of FastMCP from mcp.server.fastmcp. mcp 2.0, the Python SDK of 28 July 2026, renamed FastMCP to MCPServer, and a plain install gets mcp 2.x. Pin mcp<2 in the dependencies, or move to MCPServer as the SDK's migration guide says. The error output is above.
The cause and the fix, with the code before and after: ModuleNotFoundError: No module named 'mcp.server.fastmcp'
