Download and import a Sketchfab model by its UID.
AI agents use download_sketchfab_model to create or update resources in Blender — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Blender environment.
This tool downloads an external asset and imports it into the Blender scene, which is a write/create operation — it adds new data to the scene. It does not execute arbitrary code, delete data, or involve financial transactions. The blast radius is medium since it modifies the current Blender scene by introducing external content, which could include unwanted or malicious 3D assets.

Documented attack patterns abuse exactly the kind of access download_sketchfab_model gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Blender, and nothing reaches the server without passing your rules. This is the rule we recommend for download_sketchfab_model:
{
"version": "1",
"default": "deny",
"tools": {
"download_sketchfab_model": {
"limits": [
{
"counter": "download_sketchfab_model_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}download_sketchfab_model 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.

Download and import a Sketchfab model by its UID. It is categorised as a Write tool in the Blender MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Blender 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. Nothing to install.
download_sketchfab_model is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
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.
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.
download_sketchfab_model is provided by the Blender MCP server (vertiiii/blender-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Blender, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
