delete_devices_bulk
AI agents call delete_devices_bulk to permanently remove resources in FortiManager MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

From the tool's definition Tool name 'delete_devices_bulk' explicitly indicates bulk deletion of devices with no recovery mechanism typical of destructive operations.
