Why create_account needs a policy

Creating a financial account on a payments platform (Dock) that can hold funds, move money via Pix, and issue cards is a Financial operation. Misuse could enable fraudulent account creation, money laundering, or unauthorized access to financial infrastructure. The blast radius is critical given the direct financial implications.

From the tool's definition 'Account holds funds that can be moved via Pix or spent via issued cards' — creates a financial account capable of holding and moving funds

How to control create_account

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

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

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

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