21st MCP (formerly Magic MCP)
Search and generate production-ready React + Tailwind UI components from inside Claude Code.
The UI-component MCP from 21st.dev, renamed from Magic MCP to the unified 21st MCP: gives Claude search over a large component library and generation of modern React + Tailwind UI matched to your stack. Note the old @21st-dev/magic package is now a compatibility proxy — new installs go through the 21st CLI.
What it does
- Search a large curated library of React + Tailwind components from the agent
- Generate new UI matched to your framework and styling conventions
- Unified 21st CLI installer covers Claude Code, Cursor, VS Code, Windsurf, Codex
- Old Magic MCP package kept as a thin proxy so existing configs keep working
When to use it
Best for frontend work where you want the agent to start from real, production-grade components instead of inventing markup from scratch — dashboards, marketing pages, internal tools.
Getting started
npx @21st-dev/cli@latest init --client claude # other clients: cursor | vscode | windsurf | codex
Things to know
The rename (Magic → 21st) means most older tutorials point at the proxy package — follow 21st.dev/mcp for current setup. Generated UI still needs a design review before it ships.
