Connects Claude to the ClickUp v2 API with 37 tools spanning task CRUD, checklists, dependencies, comments, tags, and workspace navigation. The headline feature is aggressive response slimming: API responses that normally return 3,500+ characters get trimmed to under 200 by stripping feature flags, permission blobs, profile pictures, and other metadata that LLMs don't need. You get 95-97% token reductions on most operations. Reach for this when you're building task management workflows in Claude and want to avoid burning context window on verbose JSON. Requires a ClickUp Personal API Token and runs over stdio via npx.
