What retrieveAPIKeyWithId does on Fusionauth

AI agents call retrieveAPIKeyWithId to retrieve information from Fusionauth without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

This is fundamentally a Read operation as it only retrieves existing data without side effects. However, the severity is high because API keys are authentication credentials that grant significant access to systems and services. An AI agent misusing this tool to retrieve and exfiltrate API keys could compromise FusionAuth security and enable lateral movement or privilege escalation attacks.

From the tool's definition Tool name contains 'retrieve' and description states 'Retrieves an authentication API key' — a pure data retrieval operation with no modification or deletion.
