Gives Claude full read/write access to your Workflowy account through 10 tools covering the full lifecycle: search nodes, create and update them, move them around the hierarchy, mark items complete, and navigate parent/child relationships. Search results include breadcrumb paths so you know exactly where each node lives in your outline. It handles API rate limiting with smart caching and requires a Workflowy API token to authenticate. Useful when you want Claude to help organize research, manage task lists, or restructure outlines without leaving the conversation to manually edit nodes in the web interface.
