I could be wrong, but sounds like an issue with https://github.com/jlowin/fastmcp and not the MCP Python SDK? The Python SDK does not produce those banners.

yes they are adding banner off feature jlowin/fastmcp#1778 (comment)

Will close this since it is tracked in jlowin/fastmcp#1778 for fastmcp.
