What is BlenderMCP
BlenderMCP is a tool that integrates Blender withClaude AIbased on the Model Context Protocol (MCP). BlenderMCP uses a socket server to enable bidirectional communication between Blender and AI, supporting functions such as creating, modifying, and deleting 3D objects, controlling materials and colors, retrieving scene information, and running Python code in Blender. Users can quickly complete complex 3D modeling and scene operations based on Claude's natural language instructions, greatly improving creative efficiency. The tool consists of a Blender add-on and a Python server, and after installation, seamless connection can be achieved through simple configuration.
Main Features of BlenderMCP
- Object Operations: Supports creating, modifying, and deleting 3D objects, including basic geometric shapes and complex models.
- Material and Color Control: Apply and modify materials, adjust object colors and textures.
- Scene Information Retrieval: Retrieve detailed information about the current Blender scene, including object lists, properties, etc.
- Code Execution: Supports running arbitrary Python code in Blender to achieve more advanced operations.
- Scene Creation and Adjustment: Quickly generate or adjust 3D scenes based on natural language instructions, such as creating scenes in a specific style or adjusting lighting and camera positions.
Technical Principles of BlenderMCP
- Blender Add-on (addon.py): An add-on running inside Blender, responsible for creating a socket server. It receives commands from the outside, executes commands in Blender, such as creating objects, modifying materials, etc. The add-on is responsible for feeding back Blender's scene information or operation results to the external server.
- MCP Server (server.py): An independent Python server that implements the Model Context Protocol (MCP). It communicates with the Blender add-on via TCP sockets, receives instructions issued by users based on Claude AI, and converts them into commands that Blender can understand. The server processes the results returned by Blender and feeds them back to Claude AI.
- Communication Protocol: Communication is based on a JSON-based protocol. Commands are sent in the form of JSON objects, containing type and optional params. Responses are also JSON objects, containing status and result or message, feeding back operation results or error information.
