+### Transports
+
+The RAGFlow MCP server supports two transports: the legacy SSE transport (served at `/sse`), introduced on November 5, 2024 and deprecated on March 26, 2025, and the streamable-HTTP transport (served at `/mcp`). The legacy SSE transport and the streamable HTTP transport with JSON responses are enabled by default. To disable either transport, use the flags `--no-transport-sse-enabled` or `--no-transport-streamable-http-enabled`. To disable JSON responses for the streamable HTTP transport,  use the `--no-json-response` flag.
