The WebSocket Event Schema Validator acts as a gatekeeper for socket communications, ensuring that every message sent over your connection adheres to a predefined structure. By using the validate_event_payload tool, you can instantly detect missing fields or incorrect data types in incoming payloads. The server also provides verify_event_registration to confirm if an event type is officially recognized and audit_schema_registry to identify incomplete or empty definitions within your registry. This prevents inconsistent event names and malformed payloads from breaking your application logic.

Check if this WebSocket payload is valid: {"event_type": "user_login", "user_id": 123}

The payload is invalid because the `user_login` event requires a `timestamp` field in the registry.

Is the 'chat_message' event registered in my schema?

Yes, the 'chat_message' event is officially registered in the provided schema registry.

Audit my current schema registry for any errors.

The audit found 5 total events, but identified 1 incomplete definition: 'system_alert' has no structural rules defined.

The `validate_event_payload` tool extracts the event type directly from the provided payload and then performs a lookup in your provided `schemaRegistry` to find the matching rules.
