THE RISK

Why revoke_consent needs a policy

The tool permanently revokes a payment consent using a DELETE operation. This is irreversible — once a consent is revoked, it cannot be restored. While it prevents a financial transaction rather than executing one, the act of deletion/revocation is irreversible, placing it in the Destructive category.

From the tool's definition Revoke a payment consent before it is exercised. DELETE /consents/{id}

POLICY

How to control revoke_consent

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 revoke_consent:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "revoke_consent"
  ]
}

revoke_consent disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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