What delete_wildcard_fqdn does on Fortimanager
AI agents call delete_wildcard_fqdn to permanently remove resources in Fortimanager, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why delete_wildcard_fqdn is rated Critical
The tool permanently removes a wildcard FQDN entry from FortiManager, which is an irreversible destructive action. Even though the blast radius may be limited to a single FQDN definition (not critical), the action cannot be undone and affects security policy enforcement. Destructive is the appropriate category as it clearly deletes data that cannot be recovered without manual re-creation.
From the tool's definition Tool name explicitly includes 'delete'; description states 'Delete a wildcard FQDN' — irreversible removal of firewall filtering rules/definitions.
