## Why cancel_subscription is rated Critical

Canceling a subscription is a destructive action that terminates an ongoing financial arrangement. While not a direct money transfer (Financial), it irreversibly severs a customer's active subscription with permanent effects—the subscription ceases immediately and cannot be automatically restored through this tool. This ranks higher than Write (which is reversible) and Execute (which has variable effects).

From the tool's own definition: "Tool name 'cancel_subscription' combined with description 'Cancel a customer subscription' indicates irreversible termination of an active subscription, which cannot be undone without manual intervention."

Risk signals: Ends recurring revenue permanently

## Use case

AI agents call cancel_subscription to permanently remove resources in Stripe, 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 Stripe:

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