WHAT IT DOES

What playlists_focus_previous does on Propresenter

AI agents invoke playlists_focus_previous 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 playlists_focus_previous is rated High

This tool triggers an action in ProPresenter 7 — changing focus to the previous playlist — which is an external operation that affects the state of a live presentation software. It's not a simple data read, nor does it delete data, but it executes an operational command on an external system.

From the tool's definition Focus the previous playlist

RECOMMENDED RULE

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

playlists_focus_previous Rate-limited

playlists_focus_previous 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.
