WHAT IT DOES

What unity_component_get_referenceable does on Unity MCP Server

AI agents call unity_component_get_referenceable 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.

THE RISK

Low Risk

Why unity_component_get_referenceable needs a policy

This tool retrieves and filters data about available referenceable objects in Unity without modifying any state, creating assets, executing code, or performing destructive operations. It is a reconnaissance/information-gathering tool that helps users understand what can be assigned before making actual assignments.

From the tool's definition Tool name includes 'get' and description states 'Discover what objects can be assigned' and 'Returns matching scene objects and project assets' — purely a query/discovery operation with no side effects.

POLICY

How to control unity_component_get_referenceable

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_component_get_referenceable:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "unity_component_get_referenceable": {}
  }
}

unity_component_get_referenceable is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Unity MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
