Trigger a specific cue by index in a presentation by UUID
AI agents invoke trigger_presentation_cue 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 executes an action in ProPresenter 7 that triggers a presentation cue. Triggering cues typically causes side effects in the presentation (e.g., advancing slides, playing media, executing macros) whose consequences depend entirely on what the cue contains and which presentation/cue index is targeted.
From the tool's definition Tool name 'trigger_presentation_cue' and description 'Trigger a specific cue by index in a presentation by UUID' indicate active invocation of presentation cues, which are external operations whose effects depend on arguments (the cue index and presentation…
Documented attack patterns abuse exactly the kind of access trigger_presentation_cue 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 trigger_presentation_cue:
{
"version": "1",
"default": "deny",
"tools": {
"trigger_presentation_cue": {
"limits": [
{
"counter": "trigger_presentation_cue_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} trigger_presentation_cue 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 cue by index in a presentation by UUID. 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 trigger_presentation_cue: 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.
trigger_presentation_cue 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 trigger_presentation_cue 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 trigger_presentation_cue. 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.
trigger_presentation_cue 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.
Free to start. No card required.
