WHAT IT DOES

What predict_payment does on Mcp Afip

AI agents call predict_payment to retrieve information from Mcp Afip without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why predict_payment needs a policy

This tool performs predictive analysis and provides recommendations—read-only operations that retrieve or assess data without modifying state or committing financial obligations. The actual payment execution is delegated to a separate 'create_payment' tool. Since the tool neither executes code, deletes data, nor commits financial transactions, it falls squarely into the Read category with low severity.

From the tool's definition The tool 'predict_payment' analyzes payment likelihood and recommends banking options. The description states it 'Predict[s]' success and 'recommend[s]' the best bank/rail, with no mention of actually moving funds, creating financial obligations, or executing…

POLICY

How to control predict_payment

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 predict_payment:

policy.json

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

predict_payment 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.
