WHAT IT DOES

What create_device_group does on Fortimanager

AI agents use create_device_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.

RISK

Why create_device_group is rated Medium

Creating device groups in a network security appliance management system (FortiManager) is a reversible write operation that modifies the configuration state. This could allow an agent to create unauthorized administrative groupings, affecting network management and policy assignment scope, but does not directly delete data or trigger financial transactions.

From the tool's definition Tool name 'create_device_group' clearly indicates creation of a new resource (device group). Description is empty, but the name unambiguously describes a write operation that creates a new organizational entity in FortiManager.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_device_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 create_device_group, this is the rule to start with:

create_device_group Rate-limited

create_device_group stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
