Cinema4D

The Cinema4D MCP Server connects Cinema 4D to Claude, enabling prompt-assisted 3D manipulation by sending commands from Claude to Cinema4D and receiving results. This server pair lets you automate scene creation, object management, animation, and rendering through natural language prompts, improving precision and speed in your 3D workflows.

How to use

You use an MCP client (Claude Desktop) to send commands to the Cinema4D MCP Server. Start the Cinema4D socket server inside Cinema 4D, then access MCP tools in Claude Desktop by looking for the hammer icon in the input box. The available tool commands let you query the scene, create objects, modify transforms, manage MoGraph, run Python inside Cinema4D, render frames or previews, and more. Initiate actions like adding objects, adjusting materials, setting keyframes, or executing Python code directly from Claude and have them applied in Cinema 4D.

To ensure smooth operation, run the Cinema4D socket server first, then open Claude Desktop and select the Cinema4D MCP tools. Use commands to perform tasks such as creating cameras, lights, MoGraph clones, and dynamics, or to render previews and frames. The system returns context for created objects so that subsequent commands can reference those objects reliably using their identifiers.

How to install

Prerequisites: You need Cinema 4D (R2024+ recommended) and Python 3.10 or higher for the MCP Server component.

1. Clone the project repository.

git clone https://github.com/ttiimmaacc/cinema4d-mcp.git
cd cinema4d-mcp

2. Install the MCP Server package in editable mode.

pip install -e .

3. Make the wrapper script executable.

chmod +x bin/cinema4d-mcp-wrapper

4. Set up the Cinema 4D plugin inside Cinema 4D and start the socket server.

• Copy the file c4d_plugin/mcp_server_plugin.pyp to Cinema 4D's plugins directory (path varies by OS). After copying, open Cinema 4D and start the socket server from Extensions > Socket Server Plugin.

5. Configure Claude Desktop to connect to the MCP server.

// Development/unpublished server configuration
"mcpServers": {
  "cinema4d": {
    "command": "python3",
    "args": ["/Users/username/cinema4d-mcp/main.py"]
  }
}

6. If you publish the server, configure Claude Desktop to use the wrapper command.

"mcpServers": {
  "cinema4d": {
    "command": "cinema4d-mcp-wrapper",
    "args": []
  }
}
