AI agents call get_focused_presentation to retrieve information from Propresenter without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the state of the ProPresenter application to retrieve information about which presentation is currently in focus. It performs a read-only operation that retrieves data without creating, modifying, deleting, or executing any external operations. No financial, destructive, or execute-level risks are present.
From the tool's definition Tool name 'get_focused_presentation' and description 'Get the currently focused presentation' indicate a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_focused_presentation 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 get_focused_presentation:
{
"version": "1",
"default": "deny",
"tools": {
"get_focused_presentation": {}
}
}get_focused_presentation is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the currently focused presentation. It is categorised as a Read tool in the Propresenter MCP Server, which means it retrieves data without modifying state.
Register the Propresenter MCP server in PolicyLayer and add a rule for get_focused_presentation: 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.
get_focused_presentation is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_focused_presentation 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 get_focused_presentation. 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.
get_focused_presentation 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.
