Frequently asked questions

1

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`).

2

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`).

3

How do I configure logging?

Use `--log-level` to set level (`debug`, `info`, `warn`, `error`; default `info`) and `--json-logs` to output logs in JSON format (default `false`).
