List assets in the project. Can filter by path, type, and search term.
AI agents call unity_asset_list to retrieve information from Unity MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query/retrieval operation on existing project assets. It has no capability to create, modify, delete, or execute code. The filtering parameters are search criteria, not mutation operations. The blast radius of misuse is minimal—an AI agent listing assets cannot cause damage to the project or system. Classified as Read with high confidence.
From the tool's definition Tool description states 'List assets in the project' with filtering options (path, type, search term). The verb 'list' and lack of any modification language indicate a read-only operation that retrieves information without side effects.
Documented attack patterns abuse exactly the kind of access unity_asset_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Unity MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for unity_asset_list:
{
"version": "1",
"default": "deny",
"tools": {
"unity_asset_list": {}
}
}unity_asset_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List assets in the project. Can filter by path, type, and search term. It is categorised as a Read tool in the Unity MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_asset_list: 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 Server. Nothing to install.
unity_asset_list 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 unity_asset_list 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 unity_asset_list. 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.
unity_asset_list is provided by the Unity MCP Server MCP server (anklebreaker-studio/unity-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
