THE RISK

Medium Risk

Why export_gltf needs a policy

This tool creates/writes a new file (glTF format) containing garment design data. It is reversible (the exported file can be deleted or overwritten) and produces no side effects beyond file creation. The blast radius is low—misuse results in unwanted file exports, not data loss or irreversible changes to the CLO3D project itself.

From the tool's definition Tool name 'export_gltf' and description 'Export the garment as a glTF file' indicate file creation/output of design data in a standard 3D format.

POLICY

How to control export_gltf

PolicyLayer is an MCP gateway — it sits between your AI agents and CLO3D MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for export_gltf:

policy.json

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

export_gltf 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.

Create a free account and register CLO3D 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 export_gltf

What does the export_gltf tool do? +

Export the garment as a glTF file. It is categorised as a Write tool in the CLO3D 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 export_gltf? +

Register the CLO3D MCP Server MCP server in PolicyLayer and add a rule for export_gltf: 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 CLO3D MCP Server. Nothing to install.

What risk level is export_gltf? +

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

Can I rate-limit export_gltf? +

Yes. Add a rate_limit block to the export_gltf 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 export_gltf completely? +

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

export_gltf is provided by the CLO3D MCP Server MCP server (ubani-studio/clo3d-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every CLO3D MCP Server tool call.

Start from CLO3D MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
