THE RISK

High Risk

Why finalize_dispute needs a policy

This tool triggers an irreversible external operation — submitting a dispute to a card network. While it doesn't delete data, it locks the dispute state permanently and initiates an external financial review process. The inability to add further evidence makes this a high-severity Execute action (irreversible external trigger), though not Financial since it doesn't directly move money.

From the tool's definition 'submits previously added evidence to the card network for review. After finalization, no further evidence can be added.'

POLICY

How to control finalize_dispute

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 finalize_dispute:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "finalize_dispute": {
      "limits": [
        {
          "counter": "finalize_dispute_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

finalize_dispute stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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.
