## Why delete_firewall_policy is rated Critical

Deleting firewall policies is an irreversible destructive action that cannot be undone and has severe blast radius in a production environment—it directly impacts network security posture, potentially disabling critical security rules and exposing infrastructure to threats. This is more severe than Write (reversible modification) and qualifies as Destructive.

From the tool's own definition: "Tool name is 'delete_firewall_policy' with no descriptive text provided. The verb 'delete' combined with 'firewall_policy' indicates irreversible removal of security policy configuration in a centralized firewall management system (FortiManager)."

## Use case

AI agents call delete_firewall_policy to permanently remove resources in FortiManager MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches FortiManager MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_firewall_policy"
  ]
}
```
