WHAT IT DOES

What retrieveUserAction does on Fusionauth

AI agents call retrieveUserAction 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 retrieveUserAction is rated Low

This tool queries and returns user action data without side effects. The operations are read-only: fetching a specific user action by ID, returning all user actions, or filtering inactive actions. No data is created, modified, deleted, or executed. This is a straightforward data retrieval operation.

From the tool's definition Tool description states 'Retrieves the user action' and 'will return all the user actions' — core retrieval verbs with no modification, deletion, or execution indicated.
