WHAT IT DOES

What list_device_groups does on Fortimanager

AI agents call list_device_groups to retrieve information from Fortimanager without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_device_groups is rated Low

This tool queries and returns information about device groups without creating, modifying, or deleting any data. It is a straightforward read operation with minimal risk. The low severity reflects that listing device groups exposes organizational structure information but does not enable harmful actions by itself.

From the tool's definition Tool name 'list_device_groups' and description 'List all device groups' clearly indicate data retrieval with no modification or side effects.

RECOMMENDED RULE

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

list_device_groups Allowed

list_device_groups is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Fortimanager, apply this rule, and every list_device_groups call is checked against it from then on.
