AI agents call editor_get_asset_references 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 reference information about an asset in the Unreal Engine editor. The action is purely informational—it queries and returns data about asset dependencies or relationships without creating, modifying, deleting, or executing operations. This is a straightforward Read operation with minimal security risk.
From the tool's definition Tool name contains 'get' and description states 'Get references for an asset' with example output shown, indicating data retrieval with no modification capability.

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_get_asset_references:
{
"version": "1",
"default": "deny",
"tools": {
"editor_get_asset_references": {}
}
}editor_get_asset_references 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_get_asset_references: 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_get_asset_references 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_get_asset_references 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.
