notebooklm-upstream-uses-streamable-http-sse-transport

The upstream notebooklm-mcp-cli server’s HTTP transport uses streamable-http (Server-Sent Events format), not standard REST JSON responses. Direct curl calls to the MCP endpoint return SSE-formatted responses. Tool listing must be done via docker exec notebooklm-mcp python -c "import subprocess; ..." or through the MCP protocol client, not via a simple HTTP GET.
