Calculate contrast ratios directly in Cursor

When you are editing stylesheets, your Cursor agent can use `check_color_contrast` to verify readability on the fly. You do not have to copy hex codes out of your editor to test them. The MCP tool runs the actual WCAG 2.1 formula, giving Cursor the exact ratio so it can write compliant CSS without guessing the math.

Fix accessibility bugs during code generation

Let your agent run `check_color_contrast` via this MCP Server while refactoring your UI components. If a background change breaks compliance, Cursor catches it before you commit. This changes how you build interfaces by turning accessibility checks into an automated step inside your editor.

Support for all CSS color formats

Raw HEX, RGB, or HSL are all supported directly. Cursor passes your active theme variables to get instant compliance feedback. This prevents you from having to manually convert color formats before checking if your text is readable.

Setup guide

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Color Contrast Checker Alternative MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Color Contrast Checker Alternative transactions." If the MCP tools are loaded correctly, Cursor will call the Color Contrast Checker Alternative tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about Color Contrast Checker Alternative MCP in Cursor

Yes, when Cursor runs in agent mode, it uses the tool to test different color values until it finds a pair that passes WCAG AA or AAA standards.

Large language models are notoriously bad at relative luminance math. This MCP Server provides the exact mathematical ratio so your editor does not write unreadable code.

Not at all. The MCP setup runs instantly in the background, allowing your editor to get compliance data without lagging your workspace.

Yes, your editor can look up the hex values from your tailwind config and pass them directly to the contrast checker to ensure your custom theme is compliant.

Only the raw color strings are processed to calculate the luminance. The data is entirely ephemeral and wiped immediately after the calculation is returned to your editor.
