THE RISK

Low Risk

Why list_questions needs a policy

This tool retrieves or queries questions associated with a product listing, which is a read-only operation with no side effects. It does not modify, delete, execute code, or trigger financial transactions. The low severity reflects minimal risk if misused by an AI agent, as the worst outcome would be information disclosure of publicly available or user-accessible product Q&A data.

From the tool's definition Tool name 'list_questions' and description 'List questions on a product listing' indicate retrieval of existing data with no modification, deletion, or execution of external operations.

POLICY

How to control list_questions

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 list_questions:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_questions": {}
  }
}

list_questions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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.
