WHAT IT DOES

What focus_previous_presentation does on Propresenter

AI agents invoke focus_previous_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 focus_previous_presentation is rated High

This tool triggers a navigation action in ProPresenter 7, switching focus to the previous presentation. It is an external operation that changes the state of a live presentation application, qualifying as Execute. Misuse could disrupt a live event by changing the active presentation unexpectedly.

RECOMMENDED RULE

The rule that runs focus_previous_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 focus_previous_presentation, this is the rule to start with:

focus_previous_presentation Rate-limited

focus_previous_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.
