## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,

## Why pfsense_delete_services_haproxy_backends is rated Critical

The tool performs deletion of service backend configurations, which is an irreversible operation that cannot be undone. Combined with the server's scope of 'full control over pfSense firewalls' and the absence of a description to suggest safeguards, this poses a high blast radius—misconfigured deletion could disrupt load balancing and service availability. Destructive is more severe than Write or Execute.

From the tool's own definition: "Tool name contains 'delete' and targets 'services_haproxy_backends', indicating irreversible removal of HAProxy backend configurations from a pfSense firewall."

## Use case

AI agents call pfsense_delete_services_haproxy_backends 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_services_haproxy_backends"
  ]
}
```
