AI agents call props_get 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.
The tool retrieves or queries information about a prop object in ProPresenter 7. The verb 'get' and the absence of any language suggesting side effects (create, modify, delete, execute, trigger) indicate this is a read-only operation. The severity is low because retrieving prop details poses minimal risk—it cannot modify state, execute code, or cause destructive changes.
From the tool's definition Tool name 'props_get' with description 'Get details of a specific prop' indicates a retrieval operation with no modification or execution capability.
Documented attack patterns abuse exactly the kind of access props_get 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 props_get:
{
"version": "1",
"default": "deny",
"tools": {
"props_get": {}
}
}props_get is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get details of a specific prop. 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 props_get: 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.
props_get 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 props_get 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 props_get. 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.
props_get 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.
