How do I use sse tool?

[mkschreder]

I have an sse mcp server that uses two endpoints:

• /api/sse: this is the event endpoint which emits the events
• /api/messages: this is the POST endpoint for messages sent to the server

It seems that existing mcp interface expects something else (endpoints in docs are called /mcp? is this the same as the sse endpoint?)

# Create server params for the remote MCP service
    server_params = SseServerParams(
        url="http://localhost:3000/api/sse",
        headers={
            "Content-Type": "application/json",
        },
        timeout=30,  # Connection timeout in seconds
    )

    # Get the translation tool from the server
    tools = await mcp_server_tools(server_params)

When I run this code I get an error from lower levels: Error in post_writer: Redirect response '308 Permanent Redirect' for url 'http://localhost:3000/api/messages/?session_id=579d13db-4ad1-4c3b-ab4f-1838065ae99b'
Redirect location: '/api/messages?session_id=579d13db-4ad1-4c3b-ab4f-1838065ae99b'

I think this is due to how nextjs dev mode handles requests and I'm not sure if it is the redirect itself that causes autogen to fail to connect or if autogen expects a different interface.

When I connect to my server using "npx @wong2/mcp-cli --sse http://localhost:3000/api/sse" everything works and I can see the full list of tools.
