This tool queries and returns a live photo record, which is a read-only operation with no side effects. However, in the context of an Argentine tax authority (AFIP) electronic invoicing system, 'live photo' likely refers to a taxpayer's business documentation or identification photo, which could be sensitive personally identifiable information (PII).

From the tool's definition Tool name 'retrieve_live_photo' and description 'Retrieve a live photo record by id' indicate data retrieval with no modification or deletion. The word 'Retrieve' is a classic Read operation.

POLICY

How to control retrieve_live_photo

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 retrieve_live_photo:

policy.json

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

retrieve_live_photo 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.
