## Why waf_delete_rule is rated Critical

This tool permanently removes a WAF (Web Application Firewall) rule, which is a security control. Deletion is irreversible and directly impacts the security posture of the system. While not as severe as deleting entire databases, removing security rules creates exposure to attacks that the rule previously prevented.

From the tool's own definition: "Tool name contains 'delete' and description states 'Delete a WAF rule by ID.' The action is irreversible—removing a WAF security rule cannot be undone without manual recreation."

## Use case

AI agents call waf_delete_rule to permanently remove resources in Aapanel, 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 Aapanel:

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