What unity_shadergraph_info does on Unity MCP Server
AI agents call unity_shadergraph_info 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.
Why unity_shadergraph_info is rated Low
This tool only gathers and returns metadata about existing shader graph assets. It performs no writes, deletions, code execution, or side effects. The information retrieved (properties, node counts, file sizes) is non-sensitive technical metadata. Misuse by an AI agent would be limited to understanding shader graph structure without capability to modify or execute anything.
From the tool's definition Tool retrieves detailed information about shader graphs: 'exposed properties', 'node count', 'features used', 'file size', 'pass count'. These are all query/read operations with no modification or execution capability.
Attacks that exploit this kind of access
The rule that runs unity_shadergraph_info 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_info, this is the rule to start with:
unity_shadergraph_info is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Unity MCP Server, apply this rule, and every unity_shadergraph_info call is checked against it from then on.
Questions about unity_shadergraph_info
Get detailed info about a specific shader graph: exposed properties (with types, ranges), node count, features used (custom functions, sub-graphs, keywords), file size, pass count. 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_info: 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_info 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_info 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_info. 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_info 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.
