## Why list_promo_rules is rated Low

The 'list' prefix is a strong indicator of a Read operation that retrieves existing promotional rules from Mailchimp without creating, modifying, or deleting data. This has minimal blast radius if misused—an agent listing promo rules cannot cause financial harm, data loss, or external operations.

From the tool's own definition: "Tool name 'list_promo_rules' uses the 'list' verb, which typically retrieves or queries data without modification. The tool description is empty, but the naming convention strongly suggests a retrieval operation for promotional rules/data within Mailchimp."

## Use case

AI agents call list_promo_rules to retrieve information from Mailchimp MCP 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 Mailchimp MCP:

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