stripe_create_customer

THE RISK

Critical Risk

Creating a Stripe customer establishes a financial entity in the payment system that can be charged, subscribed to plans, and billed. While it doesn't immediately move money, it creates a financial obligation record and is a prerequisite for payments, making it a Financial category action. Misuse could lead to unauthorized customer creation enabling subsequent fraudulent charges.

HOW TO CONTROL STRIPE_CREATE_CUSTOMER

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

policy.json

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

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