pfsense_delete_services_haproxy_backend_acls
AI agents call pfsense_delete_services_haproxy_backend_acls 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' prefix combined with operation on firewall access control lists (ACLs) indicates an irreversible destructive action. ACLs are critical security controls in HAProxy backend configuration. Deletion cannot be undone and directly impacts firewall functionality and security posture. This is more severe than Execute/Write because the action is non-reversible and affects critical infrastructure security.
From the tool's definition Tool name contains 'delete' and operates on pfSense HAProxy backend ACLs via REST API v2. The server description indicates 'full control over pfSense firewalls' with 677 tools covering critical infrastructure.
