Running Options

• Default stdio mode: python server.py

• SSE mode (port 8000): python server.py --sse

Environment Variables

• TRANSPORT_MODE: Set to sse to run the server in SSE mode. If not set, defaults to stdio mode.

• HOST: When TRANSPORT_MODE is sse, specifies the host to bind the server to (e.g., 0.0.0.0). Defaults to 127.0.0.1.

• PORT: When TRANSPORT_MODE is sse, specifies the port to run the server on (e.g., 8080). Defaults to 8000.

Example:

TRANSPORT_MODE=sse HOST=0.0.0.0 PORT=8080 python server.py
