THE RISK

Critical Risk

Creating a subscription plan on PayPal directly enables recurring financial charges. While it doesn't immediately move money, it establishes the financial framework for recurring billing, making it a Financial category action. Misuse could result in unauthorized subscription plans being created that trap users in unwanted recurring payments.

From the tool's definition 'Create a new subscription plan' on PayPal — establishes recurring billing structures that commit financial obligations for subscribers

HOW TO CONTROL CREATE_SUBSCRIPTION_PLAN

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_subscription_plan": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to create_subscription_plan is blocked until a human approves it. The rest of the server keeps working.
