pfsense_delete_interface_groups
AI agents call pfsense_delete_interface_groups to permanently remove resources in Pfsense — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The 'delete' action on interface groups in a firewall is irreversible and affects network infrastructure. Misuse by an AI agent could sever connectivity, disrupt VPN configurations tied to interfaces, or break network segmentation. This ranks as Destructive (highest severity) rather than Execute because deletion cannot be undone.
From the tool's definition Tool name 'pfsense_delete_interface_groups' contains 'delete', indicating irreversible removal of configuration. Server context shows 677 tools controlling pfSense firewalls (critical network infrastructure).
