THE RISK

Medium Risk

Why create_pickup needs a policy

This tool creates a new resource (a pickup request) in the Argentine tax authority's invoicing system. It modifies system state by adding a new request record, but the action is reversible (the request can be cancelled or modified). This is a Write operation rather than Execute because it does not run arbitrary code or trigger external operations with argument-dependent effects.

From the tool's definition Tool name 'create_pickup' and description 'Create a pickup/collection request (retiro)' indicate a CREATE operation that establishes a new pickup/collection request in the AFIP system.

POLICY

How to control create_pickup

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_pickup:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_pickup": {
      "limits": [
        {
          "counter": "create_pickup_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_pickup stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. 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.
