THE RISK

Low Risk

Why get_recurrence needs a policy

The verb 'Retrieve' and the context of looking up a recurrence by ID are characteristic of a Read operation. This tool queries existing data without side effects, making it low severity. The confidence is high because the description is explicit about the retrieval nature of the operation.

From the tool's definition Tool name 'get_recurrence' and description 'Retrieve a recurrence by Rede recurrence id' indicate a query/retrieval operation with no modification of data.

POLICY

How to control get_recurrence

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 get_recurrence:

policy.json

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

get_recurrence 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.
