What it is

21st.dev hosts a community library of React and Tailwind components, and its Magic MCP server lets you ask your coding agent for a component in plain language ("a pricing table with a toggle") and receive one built from that library. Free tier with limits.

Why it’s here

Faster than browsing when you know roughly what you want. Treat the output as a starting point and restyle it to your system; it will come back in a generic style otherwise.

Best for

  • generating components in your agent
  • quick UI scaffolding
  • landing sections

Can my agent use this?

Agent excellent agent friendliness

Yes, this is built for agents. Install the MCP server per the docs, then describe the component you need.

Excellent: Public docs, public source or an installable package. An agent can read, install and implement this directly.
