Why expenses_report needs a policy

This tool queries and retrieves expense/purchase records from the AFIP system—a read-only operation with no side effects. While the data accessed is financial in nature (tax-relevant expenses), the tool itself performs no financial transactions, movements of money, or creation of financial obligations.

From the tool's definition Tool name 'expenses_report' and description 'Expenses/purchases report by date range' indicate data retrieval with no modification. It retrieves financial records (expenses/purchases) filtered by date range.

POLICY

How to control expenses_report

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 expenses_report:

policy.json

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

expenses_report 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.
