Shelf is a free, open-source macOS app for people who build with AI. Drop a project folder — Shelf figures out how it runs, remembers it, and launches it in one click. Connect Claude, Cursor, or Codex and they can see the same library over MCP: find a tool, launch it, check logs. New in 1.0: design profiles so agents build with your branding without you pasting hex codes. Local-first. No account. MIT.
