List all Visual Effect Graph assets in the project. Requires Visual Effect Graph package (com.unity.visualeffectgraph).
AI agents call unity_vfx_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 is a read-only operation that queries the project's Visual Effect Graph assets. It has no side effects, does not execute code, does not modify data, and does not delete or move resources. The blast radius if misused by an AI agent is minimal—it merely provides information about existing assets.
From the tool's definition Tool name 'unity_vfx_list' and description 'List all Visual Effect Graph assets in the project' indicate a query operation that retrieves and enumerates existing assets without modifying, deleting, or executing any operations.
Documented attack patterns abuse exactly the kind of access unity_vfx_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_vfx_list:
{
"version": "1",
"default": "deny",
"tools": {
"unity_vfx_list": {}
}
}unity_vfx_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all Visual Effect Graph assets in the project. Requires Visual Effect Graph package (com.unity.visualeffectgraph). 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_vfx_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_vfx_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_vfx_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_vfx_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_vfx_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.
