# Design Token Transformer MCP for AI Agents MCP

> Design Token Transformer converts and generates consistent design tokens for every platform you use. It handles the complex process of moving values between syntaxes like JSON, CSS variables, SCSS, and Tailwind, resolving aliases along the way. You can also generate full color scales or create specific dark mode themes instantly.

## Description

Working across multiple platforms means juggling dozens of styling systems. This MCP solves that headache by letting your AI client manage design tokens everywhere—from Figma definitions to live CSS variables. It takes your core design values and converts them, resolving any internal aliases so you don't have conflicting styles. Need a dark mode theme? It generates the right colors using OKLCH lightness for perfect visual consistency. Plus, if you just give it three anchor colors, it spits out a full 50-950 color weight scale you can drop straight into your system. Vinkius hosts this MCP so you connect once through any compatible client and gain instant access to reliable token conversion every time.

## Prompt Examples

**Prompt:** 
```
I need to convert these primary brand tokens from JSON into CSS variables and Tailwind classes.
```

**Response:** 
```
Here are your converted tokens:

**CSS Variables:**
```css
:root {
  --color-primary: #007bff;
}
```

**Tailwind Classes:**
*   `bg-primary`: `bg-[#007bff]`
*   `text-primary`: `text-[#007bff]`

Remember to update your config file for full integration.
```

**Prompt:** 
```
Generate a dark mode theme based on this light mode JSON: {"background": "#ffffff", "surface": "#f8f9fa"}.
```

**Response:** 
```
**Dark Mode Tokens Generated:**

Based on your input, here are the suggested adjustments for low-light environments:

*   `--color-background`: `#121212` (Deep background)
*   `--color-surface`: `#1e1e1e` (Component surface)

These values maintain high contrast and readability.
```

**Prompt:** 
```
Give me a full color scale using #f8f9fa, #6c757d, and #212529 as anchors.
```

**Response:** 
```
**Generated 50-950 Scale:**

The following palette provides full weight coverage for your brand:

| Weight | Hex Code |
| :---: | :---: | 
| **50** | `#f8f9fa` |
| **700** | `#495057` |
| **950** | `#1a1d20` |

This range covers everything from lightest backgrounds to deepest text.

```

## Capabilities

### Convert tokens between syntaxes
You pass in design definitions in one format (like JSON) and get the exact corresponding code structure in another, such as CSS or Tailwind.

### Generate dark mode themes
The MCP creates a full set of color tokens optimized for dark mode by adjusting values using OKLCH lightness standards.

### Build comprehensive color scales
It generates an entire 10-step, weighted color scale (50 through 950) based only on three initial anchor colors you provide.

## Use Cases

### Migrating an old component library
The developer needs to move a legacy component that used hardcoded colors into a modern token system. They use the MCP to take the existing JSON color definitions and generate clean, structured CSS variables for immediate adoption.

### Launching dark mode support
The product manager asks their agent to prepare the site for a dark theme. The agent calls `generate_dark_mode_tokens` using the main brand palette, delivering all necessary token adjustments optimized for visual comfort.

### Establishing a new color system
The design team has three core shades (primary, secondary, accent). They ask their agent to run `generate_color_scale`, receiving the full 50-950 spectrum needed for every component state across the whole application.

### Cross-platform token syncing
A designer updates a primary color in Figma. They ask their agent to use `transform_tokens` to update both the SCSS variables and the Tailwind utility classes simultaneously, ensuring zero discrepancies across web and mobile.

## Benefits

- Stop manually converting tokens. Use `transform_tokens` to instantly get your design definitions in CSS, SCSS, or Tailwind syntax.
- Maintain perfect brand consistency using `generate_color_scale`. You only need three anchor colors to produce a full 50-950 palette.
- Implement true dark mode without guesswork. `generate_dark_mode_tokens` handles the complex OKLCH lightness adjustments for you.
- Reduce build friction by resolving aliases automatically. The MCP ensures your tokens are always pointing to their simplest, most reliable primitive value.
- Save time debugging mismatched styles. This MCP treats design token conversion as a single action, minimizing manual cross-platform checks.

## How It Works

The bottom line is you define the tokens once and get usable, multi-format code across all necessary platforms.

1. Start by providing the source design tokens and specifying the target output format. For example, inputting a set of JSON definitions and requesting CSS.
2. The MCP processes your request, resolving all internal aliases to ensure every token points to its absolute primitive value before conversion begins.
3. Your AI client receives clean, structured code—be it SCSS, Tailwind classes, or standard CSS variables—ready for immediate implementation in your project.

## Frequently Asked Questions

**How does the Design Token Transformer MCP help with CSS variables?**
It automatically takes your defined tokens and outputs them in standard CSS variable format. This saves you from manually writing out `:root { --token: value; }` for every single color or spacing unit.

**Can the Design Token Transformer MCP handle dark mode changes?**
Yes, it's built specifically for that. You give it your light mode tokens, and it calculates the necessary contrast adjustments using advanced lightness metrics to make sure the dark theme looks right everywhere.

**What if I only have a few colors? Can I build a full palette?**
Absolutely. You don't need dozens of hex codes. Just provide three key anchor shades, and the MCP will generate a complete 50-950 scale, giving you every shade needed for component states.

**Is the Design Token Transformer MCP better than copying tokens manually?**
Yes. Manual copying fails when your token structure changes or if you have aliases. This MCP resolves those internal references automatically, guaranteeing that what you paste into Tailwind is identical to what's in your CSS variables.

**Does the Design Token Transformer MCP support multiple formats?**
It supports several major web standards. You can convert tokens between JSON, CSS, SCSS, and utility frameworks like Tailwind, making it a central hub for token management.
