WHAT IT DOES

What create_token does on Mcp Ap2

AI agents use create_token to commit financial operations through Mcp Ap2 — usually the final step of a payment, billing, or trading workflow. A call moves real money.

THE RISK

Critical Risk

Why create_token needs a policy

This tool handles payment card data (PANs) and creates payment tokens used in financial transactions. While tokenization itself doesn't move money, it directly enables financial operations and involves highly sensitive cardholder data. Misuse could expose PAN data or create tokens used for unauthorized payments, placing it firmly in the Financial category with high severity due to PCI/payment risk.

From the tool's definition Tokenize a card (POST /tokens). Returns a token id like tkn_xxx... Never send real PANs from a backend without PCI scope.

POLICY

How to control create_token

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for create_token:

policy.json

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

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

Create a free account and register Mcp Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
