AI agents use status_set_audience to create or update resources in Propresenter — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Propresenter environment.
This tool modifies the configuration of audience screens in ProPresenter 7. It creates or changes a setting (screen configuration), which is a reversible write operation. Misuse could disrupt a live presentation by altering what the audience sees.

Documented attack patterns abuse exactly the kind of access status_set_audience 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 status_set_audience:
{
"version": "1",
"default": "deny",
"tools": {
"status_set_audience": {
"limits": [
{
"counter": "status_set_audience_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}status_set_audience stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Set the configuration of audience screens. It is categorised as a Write tool in the Propresenter MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Propresenter MCP server in PolicyLayer and add a rule for status_set_audience: 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.
status_set_audience is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the status_set_audience 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 status_set_audience. 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.
status_set_audience 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.
