## Why cancel_order is rated Critical

Order cancellation is a destructive operation because it irreversibly voids a completed or in-progress order, affecting inventory, fulfillment commitments, and customer expectations. While it has financial implications (refunds may be triggered), the primary risk is the irreversible destruction of order state.

From the tool's own definition: "Tool name: 'cancel_order'; description: 'Cancel an order'. Canceling an order is an irreversible action that undoes a committed financial transaction and cannot be easily reversed without manual intervention."

## Use case

AI agents call cancel_order to permanently remove resources in Shopify Graphql, 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 Shopify Graphql:

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