## Why pfsense_delete_firewall_state is rated Critical

The tool performs an irreversible deletion operation on firewall state data via the pfSense REST API. Deleting firewall state can disrupt active connections, sessions, and network traffic flows that depend on stateful tracking. This cannot be undone without manual restoration or waiting for state timeout, making it destructive.

From the tool's own definition: "Tool name contains 'delete' and description shows DELETE HTTP method to '/api/v2/firewall/state' endpoint. This irreversibly removes firewall state entries."

## Use case

AI agents call pfsense_delete_firewall_state 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.

## Recommended policy (PolicyLayer)

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

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