Get all nodes in the currently open Amplify Shader Editor graph. Returns node IDs, types, positions, and port counts. The ASE window must be open with a shader loaded.
AI agents call unity_amplify_get_nodes 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 query/retrieval operation that reads the state of an open Amplify Shader Editor graph. It performs no mutations, deletions, code execution, or external operations. The tool simply returns metadata about existing nodes, making it a straightforward Read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description states it 'Get[s] all nodes' and 'Returns node IDs, types, positions, and port counts' — purely retrieves data about the current shader graph state with no modification or side effects.
Documented attack patterns abuse exactly the kind of access unity_amplify_get_nodes 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_amplify_get_nodes:
{
"version": "1",
"default": "deny",
"tools": {
"unity_amplify_get_nodes": {}
}
}unity_amplify_get_nodes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all nodes in the currently open Amplify Shader Editor graph. Returns node IDs, types, positions, and port counts. The ASE window must be open with a shader loaded. 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_amplify_get_nodes: 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_amplify_get_nodes 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_amplify_get_nodes 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_amplify_get_nodes. 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_amplify_get_nodes 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.
