canvas_add_standalone_node
shallowio.datadef/mcp · Verify this server
Add a single data node at an exact position, without connecting it to anything. Use when the user wants something placed somewhere specific, or when you will wire it up yourself afterwards. For building out a connected diagram, canvas_add_nodes is better — it batches and lets layout position everything. Operates on one Datadef diagram, named by diagram_id.
