THE RISK

Low Risk

Why get_card needs a policy

This tool retrieves existing card information and returns read-only data (status, masked PAN, expiry, limits). It has no side effects, does not modify data, execute commands, delete records, or move money. The data returned is already masked (PAN), limiting exposure. Misuse would only expose information already associated with the queried card ID, not enable financial transactions or data destruction.

From the tool's definition Tool name is 'get_card' and description states 'Retrieve a card by id'. The verb 'Retrieve' and action of reading card status, masked PAN, expiry, and limits indicate data retrieval with no modification or destructive capability.

POLICY

How to control get_card

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_card:

policy.json

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

get_card 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.
