Get Started

Purchase on itch.io ($15 one-time) or subscribe on Gumroad ($5/month with 7-day free trial)
Download the ZIP containing the MCP server and this addon
Follow the setup instructions below

Requirements

Blender 4.0+ (5.0 recommended)
Python 3.10+ (for the MCP server)
MCP-compatible client (Claude Code / Claude Desktop / Cursor / Windsurf)

Installation

1. Install MCP server dependencies

cd server
pip install -r requirements.txt

2. Install the Blender addon

Open Blender → Edit > Preferences > Add-ons > Install
Select the addon/ folder from the downloaded ZIP
Enable "Blender MCP Pro"
Open the 3D Viewport sidebar (N key) → BM Pro tab → Start Server

3. Configure your MCP client

Add the following to your MCP client config. Replace <path> with the actual path where you extracted the ZIP.

Claude Code (`~/.claude.json`)

{
  "mcpServers": {
    "blender-mcp-pro": {
      "command": "python",
      "args": ["<path>/server/server.py"],
      "env": {
        "BLENDER_MCP_PRO_LICENSE": "YOUR-LICENSE-KEY"
      }
    }
  }
}

Claude Desktop (`claude_desktop_config.json`)

{
  "mcpServers": {
    "blender-mcp-pro": {
      "command": "python",
      "args": ["<path>/server/server.py"],
      "env": {
        "BLENDER_MCP_PRO_LICENSE": "YOUR-LICENSE-KEY"
      }
    }
  }
}

Cursor / Windsurf

Add server/server.py in your MCP settings with the BLENDER_MCP_PRO_LICENSE environment variable.

Updating

When a new version is released:

Download the latest ZIP from your Gumroad library or itch.io
Extract and overwrite the existing server/ folder
In Blender: Edit > Preferences > Add-ons → remove the old "Blender MCP Pro"
Install the new addon/ folder and enable it
Restart Blender

Your MCP client config and license key do not need to change.

Usage

Start the addon server in Blender (N panel → BM Pro → Start Server)
Launch your MCP client (e.g., Claude Code)
Control Blender with natural language!

Streamable HTTP Transport (optional)

By default, the MCP server uses stdio transport. For remote connections or web-based clients, you can use Streamable HTTP:

python server/server.py --transport streamable-http --port 8000

Then configure your MCP client to connect to http://127.0.0.1:8000/mcp/.

Examples

"Create a Suzanne and add SubSurf and Bevel modifiers"
"Create a glass material and apply it"
"Set up three-point lighting"
"Set the camera to 85mm lens and track the object"
"Add a rotation animation"
"Render at 1920x1080 with Cycles"
