AI agents call get_unreal_project_path 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 project's file path—a read-only operation with no side effects. It poses minimal security risk as it only returns configuration data. Low severity because knowing the project path alone does not enable destructive or dangerous actions without additional context.
From the tool's definition Tool name 'get_unreal_project_path' and description 'Get the current Unreal Project path' indicate a simple query operation that retrieves project metadata without modifying state or executing operations.
Documented attack patterns abuse exactly the kind of access get_unreal_project_path 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_unreal_project_path:
{
"version": "1",
"default": "deny",
"tools": {
"get_unreal_project_path": {}
}
}get_unreal_project_path is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the current Unreal Project path. 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_unreal_project_path: 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_unreal_project_path 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_unreal_project_path 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_unreal_project_path. 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_unreal_project_path 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.
