Description

21st's hosted MCP server for building user interfaces: searching a catalogue of components, themes and templates, retrieving component code, saving bookmarks and team libraries, and generating UI with variants when hosted AI is enabled on the account. It replaces the older `@21st-dev/magic` package, which is now only a thin proxy kept for configs written before the move.
