Blender Open MCP

What it does

Connects MCP clients like Claude or Cursor to Blender 3D, allowing you to manipulate your 3D scene, create objects, and manage materials using natural language. It leverages a local Ollama LLM to translate prompts into Blender Python (bpy) commands.

Tools

• blender_get_scene_info: Provides a full summary of the current scene, including objects and render settings.
• blender_create_object: Adds primitive meshes like cubes or spheres to the scene.
• blender_modify_object: Updates location, rotation, scale, and visibility of objects.
• blender_set_material: Creates and assigns Principled BSDF materials.
• blender_render_image: Renders the current scene to a file.
• blender_execute_code: Runs arbitrary Python/bpy code directly in Blender.
• blender_download_polyhaven_asset: Downloads and imports high-quality assets from PolyHaven.

Installation

Add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "blender-open-mcp": {
      "command": "blender-mcp",
      "args": ["--transport", "stdio"]
    }
  }
}

Note: You must also install the addon.py inside Blender and start the Blender MCP server from the N-panel.
