Find all GameObjects whose name contains a pattern. Supports substring matching or regex.
AI agents call unity_search_by_name 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 is a query/search operation that only retrieves information about existing GameObjects based on name criteria. It has no capability to create, modify, delete, or execute code. The blast radius of misuse is minimal—an agent could only discover unwanted information about scene structure, not alter or execute anything.
From the tool's definition Tool searches and retrieves GameObjects by name pattern matching using substring or regex. The description indicates data retrieval with no modification capability: 'Find all GameObjects whose name contains a pattern.'
Documented attack patterns abuse exactly the kind of access unity_search_by_name 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_search_by_name:
{
"version": "1",
"default": "deny",
"tools": {
"unity_search_by_name": {}
}
}unity_search_by_name is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find all GameObjects whose name contains a pattern. Supports substring matching or regex. 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_search_by_name: 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_search_by_name 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_search_by_name 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_search_by_name. 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_search_by_name 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.
