WHAT IT DOES

What transport_pause does on Propresenter

AI agents invoke transport_pause 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 transport_pause is rated High

This tool triggers an external operation (pausing playback) on a ProPresenter presentation layer. It doesn't read data, create/modify stored data, or delete anything — it executes a control action on a running media system. Misuse could disrupt a live presentation.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

transport_pause Rate-limited

transport_pause 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 transport_pause call is checked against it from then on.

FAQ

Questions about transport_pause

What does the transport_pause tool do? +

Pause the specified layer (presentation, announcement, or audio). 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 transport_pause? +

Register the Propresenter MCP server in PolicyLayer and add a rule for transport_pause: 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 transport_pause? +

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

Can I rate-limit transport_pause? +

Yes. Add a rate_limit block to the transport_pause 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 transport_pause completely? +

Set action: deny in the PolicyLayer policy for transport_pause. 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 transport_pause? +

transport_pause 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.
