List assets registered in the UMA Global Library. Can filter by type (Slot, Overlay, Race, WardrobeRecipe) and/or name pattern.
AI agents call unity_uma_list_global_library 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 tool retrieves and displays information about assets registered in Unity's UMA (Universal Multiple Avatar) Global Library. It supports only query operations (listing and filtering) without creating, modifying, deleting, or executing any asset modifications or code. The blast radius of misuse is minimal—an agent could only enumerate library contents, not manipulate them.
From the tool's definition Tool performs listing/querying of UMA Global Library assets with optional filtering by type and name pattern. Keywords: 'List' and 'filter' indicate read-only data retrieval with no modification or execution of effects.
Documented attack patterns abuse exactly the kind of access unity_uma_list_global_library 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_uma_list_global_library:
{
"version": "1",
"default": "deny",
"tools": {
"unity_uma_list_global_library": {}
}
}unity_uma_list_global_library is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List assets registered in the UMA Global Library. Can filter by type (Slot, Overlay, Race, WardrobeRecipe) and/or name pattern. 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_uma_list_global_library: 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_uma_list_global_library 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_uma_list_global_library 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_uma_list_global_library. 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_uma_list_global_library 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.
