WHAT IT DOES

What list_fabric_devices does on Fortimanager

AI agents call list_fabric_devices 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_fabric_devices is rated Low

The tool name suggests it retrieves or enumerates fabric devices without modifying them. In the context of a FortiManager MCP server managing security appliances, listing devices is a non-destructive query operation. The empty description lowers confidence slightly, but the naming convention strongly indicates a Read category.

From the tool's definition Tool name 'list_fabric_devices' indicates a listing/query operation. The description is empty, so classification relies on the naming convention.
