Full installation guide

⚠️ Do not proceed before installing UV

Setting Up MCP in Claude AI

Open Claude AI Desktop
Navigate to Settings > Developer > Edit Config
Add the following to claude_desktop_config.json:

{
    "mcpServers": {
        "blender": {
            "command": "uvx",
            "args": [
                "blender-mcp"
            ]
        }
    }
}

Installing Blender Addon

Download the addon.py file
Open Blender
Navigate to Edit > Preferences > Add-ons
Click Install... and select addon.py
Enable the addon (Checkbox: "Interface: Blender MCP")

How to Use Blender MCP

Connecting to Claude AI

Open Blender and press N to access the 3D View Sidebar
Navigate to the BlenderMCP tab
Enable Poly Haven API (Optional)
Click "Connect to Claude"
Ensure the MCP Server is running

Example Commands

You can now interact with Blender through Claude AI by using commands like:

Create a 3D scene: "Generate a dungeon scene with a dragon guarding gold"

Demo video

Modify textures: "Make this car red and metallic"
Use Poly Haven assets: "Create a beach scene using HDRIs and rock models from Poly Haven"

Demo video

AI-generated models: "Generate a 3D garden gnome using Hyper3D Rodin"
Adjust camera: "Set up isometric camera view"
Lighting setup: "Adjust lighting to a studio environment"

Using MCP with Cursor Integration

Open Cursor Settings > MCP
Paste the command:

uvx blender-mcp
