FAQ from Nats Mcp

What environment variables are required?

NATS_URL (e.g., nats://localhost:4222) is required. Optional NATS_<ACCOUNT>_CREDS variables hold base64‑encoded credentials for each account (e.g., NATS_SYS_CREDS).

What transport types are available?

The --transport flag accepts stdio (default) or sse. With SSE, the server listens on the address specified by --sse-address (default 0.0.0.0:8000).
