THE RISK

Medium Risk

Why unity_amplify_move_node needs a policy

This tool creates or modifies data (node position) in a reversible manner. The user can move a node to a different position and undo or reposition it again. It does not execute external operations, delete data, or create financial obligations. The blast radius is low since repositioning a shader node in the editor has minimal side effects and can be easily corrected. Classified as Write with low severity.

From the tool's definition Tool description states it 'Move[s] a node to a new position in the Amplify Shader Editor graph.' Moving a node in a shader editor modifies the visual/organizational state of the graph but does not delete data, execute arbitrary code, or cause irreversible…

POLICY

How to control unity_amplify_move_node

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_move_node:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "unity_amplify_move_node": {
      "limits": [
        {
          "counter": "unity_amplify_move_node_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

unity_amplify_move_node stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about unity_amplify_move_node

What does the unity_amplify_move_node tool do? +

Move a node to a new position in the Amplify Shader Editor graph. It is categorised as a Write tool in the Unity MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on unity_amplify_move_node? +

Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_amplify_move_node: 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_amplify_move_node? +

unity_amplify_move_node is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit unity_amplify_move_node? +

Yes. Add a rate_limit block to the unity_amplify_move_node 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_amplify_move_node completely? +

Set action: deny in the PolicyLayer policy for unity_amplify_move_node. 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_amplify_move_node? +

unity_amplify_move_node 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.

Enforce policy on every Unity MCP Server tool call.

Start from Unity MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
