Find C++ code that references assets by path, or find all asset paths referenced by a symbol.
AI agents call find_asset_references to retrieve information from Unreal Project 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 asset references and which code references them—a pure query operation analogous to grep or search. It has no side effects, cannot modify data, execute code, or trigger external operations. The blast radius of misuse is minimal: an AI agent could only discover which assets are used where in the codebase, which is informational.
From the tool's definition Tool name 'find_asset_references' and description 'Find C++ code that references assets by path, or find all asset paths referenced by a symbol' indicates querying/searching existing data with no modification or execution.
Attacks that exploit this kind of access
Find C++ code that references assets by path, or find all asset paths referenced by a symbol. It is categorised as a Read tool in the Unreal Project MCP Server, which means it retrieves data without modifying state.
Register the Unreal Project MCP server in PolicyLayer and add a rule for find_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 Project. Nothing to install.
find_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 find_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.
Set action: deny in the PolicyLayer policy for find_asset_references. 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.
find_asset_references is provided by the Unreal Project MCP server (tumourlove/deprecated-unreal-project-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
