THE RISK

Low Risk

Why search_agencies needs a policy

This tool retrieves information about pickup agencies based on search criteria (service and location). It performs a query-like operation that returns matching results without creating, modifying, deleting, or executing external actions. The read-only nature and limited scope of returned information (agency details for logistical purposes) present minimal risk even if misused by an AI agent.

From the tool's definition Tool name 'search_agencies' and description 'Search pickup agencies by service and location' indicate a data retrieval operation with no side effects.

POLICY

How to control search_agencies

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 search_agencies:

policy.json

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

search_agencies 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.
