## Why list_coupons is rated Low

This tool queries and retrieves coupon data from Stripe without creating, modifying, deleting, or executing operations. It is a pure read operation with minimal risk. The blast radius is limited to information disclosure of coupon metadata, which does not expose sensitive financial data like customer payment methods or transaction details.

From the tool's own definition: "Tool name 'list_coupons' and description 'List all coupons' indicate a data retrieval operation with no side effects."

## Use case

AI agents call list_coupons to retrieve information from Stripe without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Stripe:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_coupons": {}
  }
}
```
