What is the Color Contrast Checker Alternative MCP Server?

Your agent just picked #6c757d text on a #e9ecef background. Looks fine, right? Wrong — it fails WCAG AA with a 3.9:1 ratio. Your users with low vision can't read it, and your client's accessibility audit just failed.

This MCP uses the official WCAG 2.1 relative luminance formula to calculate the exact contrast ratio between any two colors. No approximation. No hallucination. Just the math that the W3C defined.

The Superpowers

Full WCAG 2.1 Matrix: AA and AAA compliance checked for both normal text (4.5:1 / 7:1) and large text (3:1 / 4.5:1) simultaneously.
Any Color Format: Pass HEX, RGB, HSL, or CSS named colors — mix and match freely.
Human Verdict: Returns 'Excellent (AAA)', 'Good (AA)', 'Large Text Only', or 'Fail' — no ratio tables to memorize.
Exact Ratio: The precise contrast ratio to 2 decimal places, not a guess.

Built-in capabilities (1)

check_color_contrast

Pass foreground and background colors in any format (HEX, RGB, HSL, CSS name). Returns the exact contrast ratio, WCAG AA/AAA pass/fail for both normal and large text, and a human-readable verdict. AI cannot reliably calculate contrast ratios — this engine uses the official WCAG 2.1 relative luminance formula. Checks WCAG 2.1 color contrast ratio between foreground and background. Returns AA/AAA compliance for normal and large text

FAQ

Frequently asked questions

My AI says this color combination passes WCAG. Should I trust it?

No. LLMs cannot reliably calculate relative luminance — they approximate. This engine uses the exact W3C formula: L = 0.2126R + 0.7152G + 0.0722*B with sRGB gamma correction. Trust the math, not the prediction.

What's the difference between AA and AAA levels?

AA requires 4.5:1 contrast for normal text — the legal minimum in most countries. AAA requires 7:1 — the gold standard for maximum readability. Large text (18pt+) has relaxed thresholds: 3:1 for AA, 4.5:1 for AAA.

Can I mix color formats? Like HEX for foreground and a CSS name for background?

Absolutely. Pass '#333333' as foreground and 'white' as background, or 'rgb(0,0,0)' with 'hsl(0,0%,95%)' — the engine normalizes everything internally.

How does Windsurf discover MCP tools?

Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.

Can Cascade chain multiple MCP tool calls?

Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.

Does Windsurf support multiple MCP servers?

Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
