WHAT IT DOES

What trigger_active_presentation does on Propresenter

AI agents invoke trigger_active_presentation to trigger actions in Propresenter. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why trigger_active_presentation is rated High

This tool triggers/executes an external operation (presentation restart) whose effects depend on what presentation is currently active. It is not merely reading data (Read), nor is it creating/modifying persistent data (Write). Instead, it executes a command that causes ProPresenter to take an action.

From the tool's definition Tool name 'trigger_active_presentation' and description 'Retrigger the currently active presentation (starts from beginning)' indicate execution of a presentation restart operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs trigger_active_presentation safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Propresenter, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For trigger_active_presentation, this is the rule to start with:

trigger_active_presentation Rate-limited

trigger_active_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.

          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Propresenter, apply this rule, and every trigger_active_presentation call is checked against it from then on.
