21st-dev-builder-v2
Build polished websites with 21st.dev components.
What it does
Builds cohesive websites and web apps by discovering, selecting, and integrating components from 21st.dev.
When to use it
Use when the user explicitly requests 21st.dev components, websites built with them, or setup of its Magic MCP server; not for general web development.
How to use it
Give it a website or component request explicitly involving 21st.dev; it creates or updates project files with selected components.
Uses
What you need · 1
The optional Magic MCP configuration supplies the 21st.dev API key through the server's environment; ordinary component discovery and installation can proceed without MCP.
