AI agents call stage_get_screens 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 and returns stage screen configurations from ProPresenter 7. It has no side effects, does not execute operations, and does not modify or delete any data. It is a straightforward read operation that retrieves existing information about stage screen configurations.
From the tool's definition Tool name contains 'get' and description states 'Get all stage screens and their configurations' — purely retrieves data without modification, deletion, or execution of operations.
Documented attack patterns abuse exactly the kind of access stage_get_screens 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 stage_get_screens:
{
"version": "1",
"default": "deny",
"tools": {
"stage_get_screens": {}
}
}stage_get_screens is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get all stage screens and their configurations. 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 stage_get_screens: 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.
stage_get_screens 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 stage_get_screens 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 stage_get_screens. 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.
stage_get_screens 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.
