Telemetry in MCP for Blender is opt-in. Collection of your content is off by default and stays off until you explicitly turn it on.
What Is Collected
Telemetry is divided into two levels based on your consent setting.
Minimal anonymous usage record (collected by default, no opt-in):
- A randomly generated install ID and a session ID
- Tool name
- Success or failure status
- Execution duration
- MCP for Blender and Blender versions
- Operating system
- Timestamp
Content (only when you opt in):
- Prompts you send
- Code executed in Blender
- Viewport screenshots
- Scene data
- Trajectory steps
Telemetry is not linked to your name or account. Data may be used to improve MCP for Blender, for research, and to train AI models.
How to Opt In
- Open Edit → Preferences → Add-ons
- Find MCP for Blender under the Interface category
- Check Allow Telemetry
Some MCP clients also show a one-time opt-in prompt at the start of a conversation. You can uncheck Allow Telemetry at any time to stop content collection again.
How to Turn Telemetry Off Entirely
Unchecking Allow Telemetry stops content collection, but the minimal anonymous usage record is still sent. To turn off all telemetry, set DISABLE_TELEMETRY=true in your MCP client config:
{
"mcpServers": {
"blender": {
"command": "uvx",
"args": ["mcp-for-blender"],
"env": {
"DISABLE_TELEMETRY": "true"
}
}
}
