Startup checks

The server performs several pre-flight checks at startup to ensure your environment is correctly configured.

See Installation for configuration instructions for both modes.

STDIO mode - mandatory requirements

In STDIO mode, the server verifies the requirements below. If any of these checks fail (e.g., due to an invalid configuration, incorrect credentials, or a missing APOC installation), the server will not start:

  • A valid connection to your Neo4j instance.

  • The ability to execute queries.

  • The presence of the APOC plugin.

HTTP mode - verification skipped

In HTTP mode, startup verification checks are skipped because credentials come from per-request Basic Auth headers. The server starts immediately without connecting to Neo4j at startup.
