Parameters from the server's own tool schema.

RISK

Why happ_chat_messages is rated Low

Even though happ_chat_messages only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
