AI agents call list_directory to retrieve information from Unity MCP Integration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves directory contents without side effects. It performs a query/read operation similar to 'ls' or 'dir' commands. No data is modified, deleted, or executed. The severity is low because directory listing poses minimal risk even if misused by an agent—it can only expose file structure information.
From the tool's definition Tool name 'list_directory' and description 'Get a listing of all files and directories in a specified path' indicate a retrieval operation with no modification or execution of code.

Documented attack patterns abuse exactly the kind of access list_directory gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Unity MCP Integration, and nothing reaches the server without passing your rules. This is the rule we recommend for list_directory:
{
"version": "1",
"default": "deny",
"tools": {
"list_directory": {}
}
}list_directory is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a listing of all files and directories in a specified path in the Unity project. Paths are relative to the Assets folder unless absolute. For example, use. It is categorised as a Read tool in the Unity MCP Integration MCP Server, which means it retrieves data without modifying state.
Register the Unity MCP Integration MCP server in PolicyLayer and add a rule for list_directory: 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 Unity MCP Integration. Nothing to install.
list_directory 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 list_directory 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 list_directory. 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.
list_directory is provided by the Unity MCP Integration MCP server (quazaai/unitymcpintegration). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
