Implementation Reference
- src/blender_mcp/server.py:659-701 (handler)The core handler function for the 'download_sketchfab_model' tool. It is decorated with @mcp.tool() for registration and implements the logic by sending a socket command to the Blender addon with the model UID, then parsing and returning the result.
