WHAT IT DOES

What retrieveUserActionWithId does on Fusionauth

AI agents call retrieveUserActionWithId 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.

RISK

Why retrieveUserActionWithId is rated Low

This tool only performs data retrieval operations. It queries existing user action records either by ID or returns all actions if no ID is provided. There is no modification, deletion, execution, or financial operation. The retrieval of user action metadata poses minimal risk of misuse by an AI agent.

From the tool's definition Tool description states 'Retrieves the user action' and 'return all the user actions' — retrieves or queries data with no side effects.
