Why keynote_open_presentation needs a policy

Opening a file from disk triggers an external application operation (launching/activating Keynote via JavaScript for Automation), which is more than a passive read — it causes side effects in the OS and application state. It does not merely retrieve data but executes an automation action that opens a file in an external app.

How to control keynote_open_presentation

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_open_presentation:

policy.json

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

keynote_open_presentation 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.
