blender-node-graph

Typed tools for broad node graph introspection — discovering all node graphs in the scene (material, geometry, compositor) and inspecting the compositor node tree specifically. For detailed shader or geometry node editing, use blender-shader-nodes or blender-geometry-nodes respectively.

Tools

Tool	Description
list_all_node_graphs	Discover all node graphs (material, geometry, compositor) in the scene
get_compositor_node_tree	Return the full compositor node tree (nodes + links)
list_compositor_nodes	List nodes in the compositor node tree

Common workflows

• Scene node graph audit: list_all_node_graphs -> drill into specific graphs
• Compositor inspection: get_compositor_node_tree for full graph overview
• Cross-graph discovery: understand all active node trees before targeted editing
