What presentation_timeline_operation does on Propresenter
AI agents invoke presentation_timeline_operation 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.
Why presentation_timeline_operation is rated High
This tool performs an operation on a presentation's timeline (likely play, pause, stop, or similar transport controls), which triggers an external operation in ProPresenter 7. It doesn't simply read data, nor does it irreversibly delete anything — it executes a live presentation control action whose effects depend on the operation argument passed.

Attacks that exploit this kind of access
The rule that runs presentation_timeline_operation 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 presentation_timeline_operation, this is the rule to start with:
presentation_timeline_operation 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Propresenter, apply this rule, and every presentation_timeline_operation call is checked against it from then on.

presentation_timeline_operation is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the presentation_timeline_operation rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
