Controlling a running Blender session from Hermes eliminates manual context switching and enables automated 3D workflows by issuing commands over a lightweight socket.
Install and enable the Blender MCP addon in Blender, start the server, and connect Hermes to localhost:9876.
High-intent search queries and answers about installing and using this skill.
You can automate Blender workflows by using a JSON-over-TCP protocol to execute bpy code remotely. This Skill connects to a running Blender instance via a localhost socket to issue commands and capture viewport data.
To run bpy code remotely, you need Blender 4.3 or later installed on a desktop, the Blender MCP addon loaded and started, and a listening TCP socket active on localhost:9876.
Yes, retrieving scene information and capturing viewport screenshots via socket is supported. The connection exposes a JSON-over-TCP protocol to inquire about object data and capture viewport screenshots for automated 3D workflows.
Yes, Blender remote control works for automating modeling and animation pipelines. By scripting bpy code execution from Hermes, you can automate material assignments, object creation, and scene manipulation without manual context switching.
Your Blender socket connection may not work if the Blender MCP addon is not enabled or the server is not started. This Skill requires Blender 4.3+ with the addon actively listening on localhost:9876 for Hermes to connect successfully.
The best way to control a running Blender session is via a lightweight JSON-over-TCP socket. This approach allows an external application like Hermes to execute arbitrary Python code and query scene information directly in the active Blender instance.
