Routes other than root ("/") for remote MCP servers don't seem to be supported.

Routes other than root ("/") for remote MCP servers don't seem to be supported.

For example if my MCP server runs under localhost:8000/myserver and I configure localhost:8000/myserver/sse in the inspector, the sse call goes through correctly, but the messages call goes to localhost:8000/messages (not /myserver/messages), and it fails.

I see the same limitation when using claude as a client.

In my understanding this doesn't allow server developers to expose multiple servers on the same port/service under different routes.
Not 100% if this is something that can added to the inspector or not covered by the protocol.

Hi @mattia-hash is this calling out the same problem as this issue? #313
