mcp-blender-server

A Python-based Model Context Protocol (MCP) server for integrating Blender and 3D modeling capabilities with OpenClaw AI agents. This project aims to adapt and deploy blender-mcp as a dedicated MCP server for our AI Comic Studio's Phase 2 development.

Disclaimer: This is an adaptation of the original blender-mcp project. We have no official affiliation with the original blender-mcp project or its maintainers.

Features

• Blender Control: Interact with Blender to create, modify, and delete 3D objects, control materials, and inspect scenes.

• AI-powered 3D Generation: Integrate with AI 3D generation tools like Hunyuan3D and Hyper3D Rodin (via their APIs).

• Asset Management: Download models from Sketchfab and assets from Poly Haven.

• Python Code Execution: Execute arbitrary Python code within Blender.

Components

This project will adapt and contain the following core components from the original blender-mcp:

1. Blender Addon (addon.py): A Blender addon that creates a socket server within Blender to receive and execute commands. (Will be placed in the root of this repo for easy access)

2. MCP Server (src/blender_mcp/server.py): The Python server that implements the Model Context Protocol and connects to the Blender addon.

Installation and Setup (Local Development)

Prerequisites

• Blender 3.0 or newer

• Python 3.10 or newer

• uv package manager (recommended for dependency management)

Environment Setup

1. Clone the repository:

   git clone https://github.com/tinhtinhcd/mcp-blender-server
   cd mcp-blender-server

2. Install uv (if not already installed):

   curl -LsSf https://astral.sh/uv/install.sh | sh
   export PATH="$HOME/.local/bin:$PATH" # Add uv to PATH for current session

3. Create a virtual environment and install dependencies:

   uv venv
   source ./.venv/bin/activate # Activate the virtual environment
   uv pip install "mcp[cli]>=1.3.0" "supabase>=2.0.0" "tomli>=2.0.0"

   (Note: Additional dependencies from the original blender-mcp project may be added as needed.)

Running the MCP Server

To run the MCP server:

uvx mcp-blender-server

(Ensure your Blender addon is also running and connected.)

Integration with OpenClaw AI Agent

This server will be configured as an MCP server for an OpenClaw AI agent. The AI agent will send commands to this server to control Blender and manage 3D assets.
