Why props_pause_auto_clear needs a policy

This tool triggers an operational state change (pausing an auto-clear timer/behavior) on a ProPresenter prop, which is an external system action. It doesn't simply read data, nor does it create/modify/delete content — it controls the timing behavior of a presentation element. Execute is the most appropriate category. Severity is low as misuse would only affect presentation display timing.

POLICY

How to control props_pause_auto_clear

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 props_pause_auto_clear:

policy.json

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

props_pause_auto_clear 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.
