Why pages_remove_background needs a policy

This tool triggers an AI-powered image processing operation on an existing document image. It modifies the document content (background removal is potentially irreversible without undo), but primarily it executes an external AI operation. It falls under Execute as it triggers an external AI processing pipeline.

From the tool's definition Remove the background from an image in a document using AI (Creator Studio only)

POLICY

How to control pages_remove_background

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

policy.json

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

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