## Why add_device_to_group is rated Medium

This tool creates or modifies device group membership, which is a Write operation—reversible configuration change with no data deletion. Severity is high because misconfiguration of device groups in FortiManager could affect security policy enforcement across multiple managed devices.

From the tool's own definition: "Tool name 'add_device_to_group' indicates creation/modification of device grouping relationships in FortiManager."

## Use case

AI agents use add_device_to_group to create or update resources in Fortimanager, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Fortimanager environment.
