Why playlists_trigger_item needs a policy

This tool executes an external operation (triggering media playback) whose effects depend on which playlist item is specified as an argument. While not destructive or financial, it performs an action in the presentation system that affects real-time output. An AI agent misusing this could inadvertently trigger incorrect content during a live presentation, causing broadcast disruptions or audience confusion.

From the tool's definition Tool name 'playlists_trigger_item' with description 'Trigger a specific item in a playlist' indicates execution of a media playback action.

POLICY

How to control playlists_trigger_item

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 playlists_trigger_item:

policy.json

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

playlists_trigger_item 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.
