FlyonUI MCP Server is a Model Context Protocol server that lets developers create, inspire, and refactor Tailwind CSS UI blocks and components built on the FlyonUI design system, all from natural-language prompts inside their IDE. It runs as an MCP server that connects to IDEs such as VS Code, Cursor, and Windsurf, and it supports popular front-end frameworks including React, Next.js, Nuxt, Vue, and Svelte. The project is maintained by ThemeSelection and is offered free of charge.
What is FlyonUI MCP Server?
FlyonUI MCP Server is a free Tailwind AI builder that generates production-ready UI blocks, components, and landing page sections using the FlyonUI block library. It takes natural-language commands as input and returns code for the requested UI element, which can be inserted directly into your project. The server integrates into your IDE through the Model Context Protocol, so you never leave your editor. It is part of the FlyonUI ecosystem, which also includes Tailwind blocks, components, templates, and a Figma design system.

Who is it for?
- Front-end developers building Tailwind-based projects who want to speed up UI development by generating blocks directly in their IDE without switching context.
- React/Next.js teams creating landing pages and marketing sites, since the generated blocks integrate with these frameworks.
- Product designers and prototypers who need quick variations of UI sections—such as changing a theme to Shadcn or swapping buttons—to explore design options.

How does it work?
Start by following the Installation Guide to select your IDE (VS Code, Cursor, Windsurf, etc.) and set up the MCP server. Once connected, you type one of the three slash commands followed by a natural-language prompt in your editor. The server processes the prompt and returns the UI block code, which you can then insert and further customize in your project.
