THE RISK

Low Risk

Why transport_get_time needs a policy

This tool queries the current playback time state from ProPresenter 7 without modifying, executing external operations, or causing any irreversible changes. It is a simple getter that returns information about media playback status, consistent with the Read category of tools that retrieve or query data.

From the tool's definition Tool name 'transport_get_time' and description 'Get the current playback time of the specified layer' indicate a retrieval operation with no side effects.

POLICY

How to control transport_get_time

PolicyLayer is an MCP gateway — it sits between your AI agents and Propresenter, and nothing reaches the server without passing your rules. This is the rule we recommend for transport_get_time:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "transport_get_time": {}
  }
}

transport_get_time is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Propresenter — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Get the current playback time of the specified layer. It is categorised as a Read tool in the Propresenter MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on transport_get_time? +

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

Can I rate-limit transport_get_time? +

Yes. Add a rate_limit block to the transport_get_time 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_get_time completely? +

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

Enforce policy on every Propresenter tool call.

Start from Propresenter, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
