DESTRUCTIVE: Delete a firewall policy
AI agents call unifi_delete_firewall_policy to permanently remove resources in UniFi Network MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool irreversibly deletes a firewall policy, which cannot be undone. Deleting firewall policies can expose network infrastructure to unauthorized access, disrupt security controls, and have cascading effects on network protection. The explicit 'DESTRUCTIVE' label in the description confirms this categorization.
From the tool's definition Tool name: 'unifi_delete_firewall_policy'; description explicitly states 'DESTRUCTIVE: Delete a firewall policy'
