Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|
| NACRE_SERVICE_KEY | yes | yes | Service-account key for STDIO mode. The server also needs the deployment's full environment (database and backend configuration) - see docs/mcp.md; the key alone is not enough to start it. |
