Why trigger_focused_presentation needs a policy

This tool executes an external operation (triggering a presentation) whose effects depend on the current state of the system (which presentation is focused). The action is not a simple read, creates no persistent data modifications, and is not destructive or financial.

From the tool's definition Tool name 'trigger_focused_presentation' and description 'Trigger the currently focused presentation' indicate an action that activates or starts playback of a presentation in ProPresenter 7, a live presentation software.

POLICY

How to control trigger_focused_presentation

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

policy.json

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

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