Why track_order_invoice needs a policy

This tool modifies invoice records by updating tracking information. It is reversible (tracking info can be corrected), so it falls under Write rather than Destructive. While it operates in a financial context (invoices), it does not directly move money or create financial obligations—it merely updates metadata on existing financial documents.

From the tool's definition Tool name 'track_order_invoice' and description 'Update tracking info for a previously issued invoice' indicate modification of existing invoice data.

POLICY

How to control track_order_invoice

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for track_order_invoice:

policy.json

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

track_order_invoice 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 Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
