WHAT IT DOES

What transport_skip_forward does on Propresenter

AI agents invoke transport_skip_forward 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_skip_forward is rated High

This tool executes a transport control action (skip forward) on a playback layer in ProPresenter, which is an external operation that changes the current playback state. It is not merely reading data, nor does it delete or modify stored content — it controls live presentation playback, placing it in the Execute category.

From the tool's definition 'Skip forward in the specified layer by a given time' — triggers a transport/playback operation that advances position in a media layer

Attacks that exploit this kind of access

RECOMMENDED RULE

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

transport_skip_forward Rate-limited

transport_skip_forward 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_skip_forward call is checked against it from then on.

FAQ

Questions about transport_skip_forward

What does the transport_skip_forward tool do? +

Skip forward in the specified layer by a given time. 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_skip_forward? +

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

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

Can I rate-limit transport_skip_forward? +

Yes. Add a rate_limit block to the transport_skip_forward 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_skip_forward completely? +

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

transport_skip_forward 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.
