Why keynote_stop_slideshow needs a policy

This tool executes a command to stop a running slideshow, which is an external operation with side effects (state change in the Keynote application). While the blast radius is minimal—stopping a slideshow is non-destructive and non-financial—it still constitutes an Execute action because it triggers application behavior based on invocation.

From the tool's definition Tool name 'keynote_stop_slideshow' and description 'Stop a running slideshow' indicate an action that triggers an external operation (halting an active Keynote slideshow process).

POLICY

How to control keynote_stop_slideshow

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 keynote_stop_slideshow:

policy.json

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

keynote_stop_slideshow 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.
