pfsense_delete_vpn_wireguard_peer
AI agents call pfsense_delete_vpn_wireguard_peer 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 indicates irreversible removal of configuration. Deleting a WireGuard VPN peer removes network connectivity for that peer and cannot be undone without manual reconfiguration. On a production firewall controlling network access, this has severe blast radius. Classified as Destructive (not Execute) because deletion is inherently irreversible.
From the tool's definition Tool name contains 'delete' and 'vpn_wireguard_peer'; server description states tools cover 'VPN' and give 'full control over pfSense firewalls'; sibling tools include create/delete operations.
