## Why retrieveApplication is rated Low

From the tool's own definition: "Tool name is 'retrieveApplication' and description states 'Retrieves all the applications that are currently inactive' and 'Retrieves the application for the given Id or all the applications if the Id is null.' The verbs 'retrieves' indicate data query with…"

## Use case

AI agents call retrieveApplication 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.

## Recommended policy (PolicyLayer)
