List all Assembly Definition files in the project. Returns name, path, reference count, and platform info for each.
AI agents call unity_asmdef_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 retrieval operation that inspects existing Assembly Definition files and returns information about them. There are no side effects, no code execution, no data modification, and no destructive actions. It is purely informational and fits the Read category (search, list, get, fetch). The severity is low because listing project files poses minimal risk even if misused by an AI agent.

Documented attack patterns abuse exactly the kind of access unity_asmdef_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_asmdef_list:
{
"version": "1",
"default": "deny",
"tools": {
"unity_asmdef_list": {}
}
}unity_asmdef_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all Assembly Definition files in the project. Returns name, path, reference count, and platform info for each. 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_asmdef_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_asmdef_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_asmdef_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_asmdef_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_asmdef_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.
