You can control Blender remotely by sending JSON messages with type and params over a TCP socket on port 9876. This socket-based protocol lets you execute arbitrary bpy Python code to create or modify 3D objects, materials, and animations from an external automation client.

You need a running Blender instance with the Blender addon server started. Your automation client must then connect to localhost:9876 using the TCP socket protocol to begin sending JSON commands for remote 3D scene manipulation.

Yes, you can execute arbitrary Blender Python (bpy) code through the socket connection. By sending execute_code commands with the required JSON message structure, you can query scene information and create or modify 3D objects, materials, and animations in real time.

Yes, the socket-based protocol operates across a local network or development setup. By connecting your client to the Blender addon server running on TCP port 9876, you can issue remote automation commands for 3D scene modification.

Automating Blender tasks via a socket protocol eliminates manual UI work, allowing artists and developers to rapidly create or modify 3D scenes. This enables real-time, programmatic control over objects, materials, and animations directly from external scripts.

Blender 3D automation via TCP socket requires the local Blender addon server to remain actively running. Communication is limited to JSON messages with type and params fields, and all remote operations depend on a stable localhost or local network connection.
