Lists files and directories in the project.
AI agents call list_assets to retrieve information from MCP For Unity without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and enumerates existing project assets without side effects. It is a read-only query operation that provides visibility into the project structure. Although it runs within a Unity Editor context controlled by an MCP server, the tool itself performs no write, destructive, execute, or financial operations.
From the tool's definition Tool name 'list_assets' and description 'Lists files and directories in the project' indicate retrieval of directory structure with no modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Lists files and directories in the project. It is categorised as a Read tool in the MCP For Unity MCP Server, which means it retrieves data without modifying state.
Register the MCP For Unity MCP server in PolicyLayer and add a rule for list_assets: 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 MCP For Unity. Nothing to install.
list_assets 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_assets 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_assets. 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_assets is provided by the MCP For Unity MCP server (yunuscan/mcpforunity). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
