POLICY

How to control add_to_wholefoods_cart

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Cart MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for add_to_wholefoods_cart:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "add_to_wholefoods_cart": {
      "limits": [
        {
          "counter": "add_to_wholefoods_cart_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

add_to_wholefoods_cart stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
