I was testing this just today and realized that MCPServerStreamableHTTP also has the sse_read_timeout, which (I think?) doesn't make any sense in the context of the streamable http.

Can we improve not having it or stating that the sse_read_timeout doesn't have any effect for the MCPServerStreamableHTTP class?

It does make sense. Streamable HTTP also offers SSE.
