How do I configure the connection to NebulaGraph?

Set environment variables `NEBULA_HOST`, `NEBULA_PORT`, `NEBULA_USER`, `NEBULA_PASSWORD`, and `NEBULA_VERSION` in a `.env` file or in your shell. The server reads these at startup.

Does the server support NebulaGraph v5?

No. Only v3 is supported until the project is updated for v5 compatibility.

What credentials does it need?

It reads `NEBULA_HOST` 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.
