## Why delete_coupon is rated Critical

This tool irreversibly deletes coupon data with no undo capability. Permanent deletion of business-critical discount codes could disrupt promotional campaigns, customer offers, and revenue operations. The high severity reflects potential business disruption if an AI agent misuses this to delete coupons without authorization.

From the tool's own definition: "Tool name is 'delete_coupon' and description states 'Delete a coupon permanently'. The word 'permanently' explicitly indicates an irreversible deletion operation."

## Use case

AI agents call delete_coupon to permanently remove resources in Ghl, 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 Ghl:

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