WHAT IT DOES

What unity_shadergraph_list_subgraphs does on Unity MCP Server

AI agents call unity_shadergraph_list_subgraphs to retrieve information from Unity MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why unity_shadergraph_list_subgraphs is rated Low

This tool queries and returns information about existing shader subgraph assets. It performs no writes, deletions, code execution, or external operations. The blast radius of misuse is minimal — an AI agent could only enumerate subgraph resources in the project, which is non-destructive discovery.

From the tool's definition Tool name contains 'list' and description states 'List all Sub Graph assets in the project' — this is a retrieval operation with no modification or side effects.

RECOMMENDED RULE

The rule that runs unity_shadergraph_list_subgraphs safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Unity MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unity_shadergraph_list_subgraphs, this is the rule to start with:

unity_shadergraph_list_subgraphs Allowed

unity_shadergraph_list_subgraphs is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Unity MCP Server, apply this rule, and every unity_shadergraph_list_subgraphs call is checked against it from then on.

FAQ

Questions about unity_shadergraph_list_subgraphs

What does the unity_shadergraph_list_subgraphs tool do? +

List all Sub Graph (.shadersubgraph) assets in the project. Sub Graphs are reusable node groups for Shader Graphs. Requires Shader Graph package. It is categorised as a Read tool in the Unity MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on unity_shadergraph_list_subgraphs? +

Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_shadergraph_list_subgraphs: 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.

What risk level is unity_shadergraph_list_subgraphs? +

unity_shadergraph_list_subgraphs is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit unity_shadergraph_list_subgraphs? +

Yes. Add a rate_limit block to the unity_shadergraph_list_subgraphs 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.

How do I block unity_shadergraph_list_subgraphs completely? +

Set action: deny in the PolicyLayer policy for unity_shadergraph_list_subgraphs. 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.

What MCP server provides unity_shadergraph_list_subgraphs? +

unity_shadergraph_list_subgraphs 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.
