Why unity_scriptableobject_list_types needs a policy

This tool retrieves information about available ScriptableObject types in a Unity project with no side effects. It performs a read-only query to enumerate existing types, analogous to a list or get operation. There is no data modification, code execution, destruction, or financial impact. The low severity reflects minimal blast radius if an AI agent calls this tool.

From the tool's definition The tool name contains 'list' and the description explicitly states it 'List all available ScriptableObject types' without any modification, creation, or deletion of data. It is purely a discovery/query operation.

POLICY

How to control unity_scriptableobject_list_types

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_scriptableobject_list_types:

policy.json

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

unity_scriptableobject_list_types 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.

FAQ

Questions about unity_scriptableobject_list_types

What does the unity_scriptableobject_list_types tool do? +

List all available ScriptableObject types in the project. Useful for discovering what SO types can be created. 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_scriptableobject_list_types? +

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

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

Can I rate-limit unity_scriptableobject_list_types? +

Yes. Add a rate_limit block to the unity_scriptableobject_list_types 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_scriptableobject_list_types completely? +

Set action: deny in the PolicyLayer policy for unity_scriptableobject_list_types. 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_scriptableobject_list_types? +

unity_scriptableobject_list_types 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.
