Check which graph packages are installed: Shader Graph (com.unity.shadergraph) and Visual Effect Graph (com.unity.visualeffectgraph). Returns available commands based on installed packages.
AI agents call unity_shadergraph_status 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 read-only status check to determine which shader and visual effect graph packages are present in a Unity project. It retrieves state information and returns available commands but does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal—incorrect status information could at worst lead to ineffective follow-up commands, not system damage or data loss.
From the tool's definition Tool description states it 'Check[s] which graph packages are installed' and 'Returns available commands based on installed packages.' These are query/inspection operations with no side effects.
Documented attack patterns abuse exactly the kind of access unity_shadergraph_status 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_shadergraph_status:
{
"version": "1",
"default": "deny",
"tools": {
"unity_shadergraph_status": {}
}
}unity_shadergraph_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check which graph packages are installed: Shader Graph (com.unity.shadergraph) and Visual Effect Graph (com.unity.visualeffectgraph). Returns available commands based on installed packages. 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_shadergraph_status: 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_shadergraph_status 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_shadergraph_status 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_shadergraph_status. 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_shadergraph_status 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.
