Get the actors currently selected in the Unreal Editor.
AI agents call get_selected_actors to retrieve information from Unreal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the current state of the Unreal Editor (which actors are selected) with no side effects, no data modification, and no execution of operations. It is a pure query/fetch operation, fitting the 'Read' category. The severity is low because misuse would only expose selection information, not cause any destructive, financial, or dangerous side effects.
From the tool's definition Tool name 'get_selected_actors' and description 'Get the actors currently selected in the Unreal Editor' indicate a read-only query operation that retrieves current selection state without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access get_selected_actors gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Unreal, and nothing reaches the server without passing your rules. This is the rule we recommend for get_selected_actors:
{
"version": "1",
"default": "deny",
"tools": {
"get_selected_actors": {}
}
}get_selected_actors is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the actors currently selected in the Unreal Editor. It is categorised as a Read tool in the Unreal MCP Server, which means it retrieves data without modifying state.
Register the Unreal MCP server in PolicyLayer and add a rule for get_selected_actors: 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 Unreal. Nothing to install.
get_selected_actors 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_selected_actors 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_selected_actors. 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_selected_actors is provided by the Unreal MCP server (runeape-sats/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
