WHAT IT DOES

What focus_presentation does on Propresenter

AI agents invoke focus_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_presentation is rated High

Focusing a presentation in ProPresenter is an external operation that changes the application's state (which presentation is in focus), but does not display/trigger content. It triggers an action in an external application (ProPresenter 7), making it Execute rather than Read or Write. Severity is low as it only changes focus state without displaying content.

RECOMMENDED RULE

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

focus_presentation Rate-limited

focus_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.

    "focus_presentation": {
      "limits": [
        {
          "counter": "focus_presentation_rate",
          "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 focus_presentation call is checked against it from then on.

FAQ

Questions about focus_presentation

What does the focus_presentation tool do? +

Focus a presentation without triggering it. It is categorised as a Execute tool in the Propresenter MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on focus_presentation? +

Register the Propresenter MCP server in PolicyLayer and add a rule for focus_presentation: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Propresenter. Nothing to install.

What risk level is focus_presentation? +

focus_presentation is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit focus_presentation? +

Yes. Add a rate_limit block to the focus_presentation 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.

How do I block focus_presentation completely? +

Set action: deny in the PolicyLayer policy for focus_presentation. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides focus_presentation? +

focus_presentation is provided by the Propresenter MCP server (@alxpark/propresenter-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
