What remove_device_from_group does on Fortimanager
AI agents call remove_device_from_group to permanently remove resources in Fortimanager, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why remove_device_from_group is rated Critical
The tool name strongly suggests it removes a device from a group in FortiManager. Removing a device from a group can have significant network policy implications (the device may lose policy configurations applied via that group). While the description is empty (lowering confidence), the naming convention combined with sibling tools like 'add_device_to_group' suggests this is the inverse destructive operation.
From the tool's definition Tool name 'remove_device_from_group' implies removal of a device association from a group, which is a potentially irreversible operational change in a network management context.
Attacks that exploit this kind of access
The rule that runs remove_device_from_group safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Fortimanager, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For remove_device_from_group, this is the rule to start with:
remove_device_from_group is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Fortimanager, apply this rule, and every remove_device_from_group call is checked against it from then on.
