## Description

Working with Tailwind v4 means your design tokens now live inside your CSS files instead of a JavaScript config. This change makes it much harder for an AI client to know exactly what styles are available in your project. You can't just ask it to use the primary color if it can't see the definition in the @theme block. This MCP solves that by letting your agent peek directly into your CSS configuration. It finds the specific theme section, pulls out every defined variable, and organizes them into a format your agent can actually use to write accurate code. When you connect this through Vinkius, you're giving your AI client the context it needs to stop guessing and start building with your actual design system.

## Tools

### extract_tailwind_variables
Scans your CSS to find and list all variables within a Tailwind v4 @theme block. It returns the variable names, their values, and the categories they belong to.

## Prompt Examples
