The MCP spec mandates the use of two separate endpoints

• one for SSE stream (i.e. server-to-client communication)
• one for commands (i.e. client-to-server communication)

Here's the excerpt from the spec

The server MUST provide two endpoints:

1. An SSE endpoint, for clients to establish a connection and receive messages from the server
2. A regular HTTP POST endpoint for clients to send messages to the server

Code at these lines only expose one, which works fine in some cases, but is not 100% adherent to the spec.

I'd say this is a minor bug, but it's worth mentioning and possibly fixing.
