Get detailed mesh geometry information: vertex count, triangle count, submeshes, UV channels, blend shapes, bone count, bounds. Works on mesh assets or scene GameObjects with MeshFilter/SkinnedMeshRenderer.
AI agents call unity_graphics_mesh_info 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 queries and returns information about mesh structures without creating, modifying, or destroying any data. It performs a passive inspection operation with no side effects on the game project, assets, or scene state. The blast radius of misuse is minimal—an agent could retrieve information it shouldn't see, but cannot cause damage or perform unwanted changes.
From the tool's definition Tool retrieves mesh geometry metadata (vertex count, triangle count, submeshes, UV channels, blend shapes, bone count, bounds) from existing mesh assets or GameObjects.
Documented attack patterns abuse exactly the kind of access unity_graphics_mesh_info 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_graphics_mesh_info:
{
"version": "1",
"default": "deny",
"tools": {
"unity_graphics_mesh_info": {}
}
}unity_graphics_mesh_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed mesh geometry information: vertex count, triangle count, submeshes, UV channels, blend shapes, bone count, bounds. Works on mesh assets or scene GameObjects with MeshFilter/SkinnedMeshRenderer. 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_graphics_mesh_info: 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_graphics_mesh_info 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_graphics_mesh_info 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_graphics_mesh_info. 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_graphics_mesh_info 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.
