AI agents call editor_search_assets 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 asset information based on search criteria (name, path, class filter). It performs a query operation with no side effects—no creation, modification, deletion, or execution of code. The read-only nature of asset search places it firmly in the Read category with low severity, as the worst case is retrieval of unintended asset metadata.
From the tool's definition Tool description: 'Search for assets by name or path with optional class filter' - search operation with query parameters only, no mutation capability.
Documented attack patterns abuse exactly the kind of access editor_search_assets 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 editor_search_assets:
{
"version": "1",
"default": "deny",
"tools": {
"editor_search_assets": {}
}
}editor_search_assets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Unreal MCP server in PolicyLayer and add a rule for editor_search_assets: 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.
editor_search_assets 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 editor_search_assets 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 editor_search_assets. 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.
editor_search_assets is provided by the Unreal MCP server (runreal/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
