Contrast Checker Mcp

Contrast Checker MCP is a Model Context Protocol (MCP) server designed for seamless integration with AI assistants like Claude, Cursor, and MCP-compatible clients. It provides robust tools for checking color contrast ratios for web and UI accessibility (WCAG 2.1), including handling alpha compositing, pass/fail evaluation for multiple WCAG levels, and suggesting accessible color replacements. It also parses and converts colors across standard formats. This server is ideal for developers, designers, accessibility auditors, and anyone creating or reviewing digital content who needs automated, standards-compliant color accessibility checks directly within their AI workflows and dev environments.
