Why download_sketchfab_model needs a policy

This tool fetches an external asset from Sketchfab and imports it into the Blender scene. It triggers an external network operation (download) and modifies the current Blender scene state (import), which constitutes an Execute-level action with side effects. The blast radius is high because it pulls arbitrary third-party content into the environment and modifies the active scene.

POLICY

How to control download_sketchfab_model

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "download_sketchfab_model": {
      "limits": [
        {
          "counter": "download_sketchfab_model_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

download_sketchfab_model stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Blender MCP for Antigravity — 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 download_sketchfab_model

What does the download_sketchfab_model tool do? +

Download and import a Sketchfab model by its UID. It is categorised as a Execute tool in the Blender MCP for Antigravity MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on download_sketchfab_model? +

Register the Blender MCP for Antigravity MCP server in PolicyLayer and add a rule for download_sketchfab_model: 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 Blender MCP for Antigravity. Nothing to install.

What risk level is download_sketchfab_model? +

download_sketchfab_model is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit download_sketchfab_model? +

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

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

download_sketchfab_model is provided by the Blender MCP for Antigravity MCP server (kc0ed/blender-mcp-for-antigravity). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Blender MCP for Antigravity tool call.

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