About 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.
Google ADK natively supports Color Contrast Checker Alternative as an MCP tool provider. declare Vinkius Edge URL and the framework handles discovery, validation, and execution automatically. Combine 1 tools with Gemini's long-context reasoning for complex multi-tool workflows, with production-ready session management and evaluation built in.
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.
