THE RISK

Medium Risk

Why close_ticket needs a policy

The tool closes (updates the state of) a support ticket. This is a Write action because it modifies data reversibly—the ticket state can be reopened if needed. While it affects administrative records, the blast radius is medium: misuse could suppress legitimate support requests or improperly close cases without resolution, impacting users' ability to resolve tax authority issues, but the action itself is not…

From the tool's definition 'Close an open support ticket' modifies the state of a ticket from open to closed, which is a reversible change to data in the AFIP system.

POLICY

How to control close_ticket

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 close_ticket:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "close_ticket": {
      "limits": [
        {
          "counter": "close_ticket_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

close_ticket stays usable, but capped — an agent stuck in a loop can't make hundreds of changes 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.
