# Color Code Converter & Contrast Checker MCP for AI Agents MCP

> Color Code Converter & Contrast Checker MCP handles color format translations and WCAG 2.1 accessibility audits. It lets your AI agent convert between Hex, RGB, and HSL while checking if color pairs meet AA or AAA legibility standards for web and app design.

## Description

Designing for the web often feels like a constant loop of manual math and checking color palettes against accessibility guidelines. You find a hex code you like, but then you have to manually convert it to RGB for your CSS or HSL for your design system. Even worse, you have to squint at the screen or use a separate browser extension to make sure your text is actually readable for users with visual impairments. 

This MCP changes that workflow by giving your AI client direct access to color math and accessibility standards. Instead of jumping between tabs, you can just ask your agent to swap color formats or verify if a specific background and text color combination passes WCAG 2.1 requirements. It handles the heavy lifting of calculating contrast ratios and checking compliance levels instantly. By connecting this to your preferred workspace through the Vinkius catalog, you turn your AI into a specialized design assistant that ensures every color choice is both technically correct and accessible to everyone.

## Tools

### calculate_contrast_ratio
Finds the exact numerical contrast between two colors. It's useful for checking legibility quickly.

### check_accessibility_compliance
Validates if a color pair meets WCAG 2.1 AA or AAA standards. This ensures your designs are accessible.

### convert_color_format
Translates a color value between Hex, RGB, and HSL. It saves you from manual math in your workflow.

## Prompt Examples

**Prompt:** 
```
Convert #3498db to RGB and HSL.
```

**Response:** 
```
Here are the converted values for **#3498db**:

| Format | Value |
| :--- | :--- |
| **RGB** | `rgb(52, 152, 219)` |
| **HSL** | `hsl(204, 70%, 53%)` |
```

**Prompt:** 
```
Does white text on #f1c40f pass WCAG AA standards?
```

**Response:** 
```
No, white text on **#f1c40f** (Sunflower) does not pass the WCAG 2.1 AA standard. 

The contrast ratio is only **1.54:1**, which is well below the required **4.5:1** for normal text.
```

**Prompt:** 
```
What is the contrast ratio between #000000 and #FFFFFF?
```

**Response:** 
```
The contrast ratio between **#000000** (Black) and **#FFFFFF** (White) is **21.0:1**. 

This is the highest possible contrast ratio and passes all WCAG 2.1 levels (AAA).
```

## Capabilities

### Swap color formats
Change values between Hex, RGB, and HSL without manual calculation.

### Calculate contrast ratios
Get the exact numerical relationship between two specific colors.

### Verify accessibility compliance
Check if color combinations meet WCAG 2.1 AA or AAA standards.

### Audit color pairs
Confirm text legibility for specific UI elements using mathematical validation.

## Use Cases

### Fixing low-contrast text
A designer realizes their brand blue is too light for white text and asks their agent to find a darker shade that passes AAA standards.

### Rapid CSS prototyping
A developer has a Hex code from a Figma file and needs to quickly get the HSL equivalent to use in a CSS variable.

### Accessibility auditing
An engineer needs to verify if a dark mode palette meets WCAG 2.1 AA requirements before a production push.

### Color palette generation
A designer wants to create a monochromatic scheme and needs to convert various shades between different formats.

## Benefits

- Eliminate manual color math by using convert_color_format for instant translations.
- Ensure legal compliance by using check_accessibility_compliance for WCAG 2.1 audits.
- Speed up CSS workflows by getting RGB and HSL values directly from your agent.
- Avoid design errors by using calculate_contrast_ratio to verify text legibility.
- Maintain consistent design systems with rapid color space transformations.

## How It Works

The bottom line is you stop doing color math by hand and start designing with guaranteed accessibility.

1. Connect the MCP to your AI client via Vinkius
2. Provide your agent with color values or design requirements
3. Receive instant conversions or accessibility pass/fail results
