Even though it is restricted to unpaid boletos, the cancellation itself is non-reversible and affects official financial records maintained by AFIP. This meets the Destructive category definition (irreversibly deletes or overwrites data, actions that cannot be undone).

From the tool's definition Tool name 'delete_boleto' and description 'Cancel an issued boleto (only allowed while unpaid / in' — the word 'Cancel' and 'delete' indicate irreversible removal of a financial document issued by the Argentine tax authority (AFIP).

How to control delete_boleto

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 delete_boleto:

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_boleto"
  ]
}

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

  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
