Brady Johnston — creator of Molecular Nodes — has been building a great node wrapper, nodebpy, for writing Blender node trees in Python.
This Nodebpy extension is a wrapper on top of it that makes those interactions easier from the Blender UI.
The source code is available on GitHub.
Drag the button below onto a running Blender window — drop it twice: first to add the repository, then to install the add-on.
