Take a detailed memory snapshot using the Memory Profiler package (com.unity.memoryprofiler). Requires the package to be installed. The snapshot can be inspected in the Memory Profiler window. Returns an error with alternatives if the package is not installed.
AI agents call unity_memory_snapshot 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.
A memory snapshot is a read/diagnostic operation that captures the current state of memory for inspection purposes. It does not modify, delete, or execute any game logic — it simply records a point-in-time view of memory. This is a non-destructive profiling action with minimal blast radius.

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

Take a detailed memory snapshot using the Memory Profiler package (com.unity.memoryprofiler). Requires the package to be installed. The snapshot can be inspected in the Memory Profiler window. Returns an error with alternatives if the package is not installed. 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_memory_snapshot: 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_memory_snapshot 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_memory_snapshot 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_memory_snapshot. 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_memory_snapshot 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.
