21st MCP (Magic MCP)
Search and publish React and Tailwind components from your AI editor through 21st.dev's MCP server.
Sources and review
Checked against public documentation on . Suitability guidance is our editorial judgment; this is not a performance benchmark or an endorsement.
Front-end work in an AI editor where you want existing React and Tailwind components pulled in rather than written from scratch.
You need it without an account: the server requires a 21st.dev API key, and generation tools appear only when AI access is enabled.
About 21st MCP (Magic MCP)
21st.dev's MCP server, formerly Magic MCP, lets coding agents in Cursor, Claude Code, Windsurf and other clients search a library of more than 10,000 React and Tailwind components and publish their own; generation tools appear when AI access is enabled on the account. It is a hosted HTTP server authenticated with a 21st.dev API key. The open-source @21st-dev/magic package is now a thin proxy that keeps older configurations working.
21st MCP (Magic MCP) is an open-source project written primarily in TypeScript, with 5.9k stars on GitHub. It was last updated in September 2026.
