How do I configure authentication?

Set the `LABEL_STUDIO_API_KEY` environment variable to your Label Studio user account API key, and `LABEL_STUDIO_URL` to the URL of your Label Studio instance.

Where does my data live?

All data remains in your Label Studio instance. The server only reads from and writes to that instance via its API; it does not store data locally.

What credentials does it need?

It reads `LABEL_STUDIO_API_KEY`, `LABEL_STUDIO_URL` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
