Trigger a specific presentation item in the active playlist
AI agents invoke playlists_trigger_active_presentation_item 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.
This tool directly executes a command that changes the state of the ProPresenter application by advancing to or selecting a specific presentation item. The effect is not merely a data retrieval (Read), nor is it reversible in the sense of simple modifications (Write) — it actively triggers a presentation state change that affects what is currently being displayed, which could impact a live presentation or broadcast.
From the tool's definition Tool name contains 'trigger' and description states 'Trigger a specific presentation item in the active playlist' — triggering a presentation item executes an external operation (advancing/changing the displayed presentation content) whose effects depend on…
Documented attack patterns abuse exactly the kind of access playlists_trigger_active_presentation_item gives an agent:
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 playlists_trigger_active_presentation_item:
{
"version": "1",
"default": "deny",
"tools": {
"playlists_trigger_active_presentation_item": {
"limits": [
{
"counter": "playlists_trigger_active_presentation_item_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} playlists_trigger_active_presentation_item 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.

Trigger a specific presentation item in the active playlist. 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.
Register the Propresenter MCP server in PolicyLayer and add a rule for playlists_trigger_active_presentation_item: 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.
playlists_trigger_active_presentation_item 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 playlists_trigger_active_presentation_item 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.
Set action: deny in the PolicyLayer policy for playlists_trigger_active_presentation_item. 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.
playlists_trigger_active_presentation_item 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.
Start from Propresenter, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
