Inject perfect color variables into Cursor

The `convert_color` tool injects mathematically precise color values directly into your Cursor editor. When you run this MCP Server inside Cursor, the tool lets your editor generate accurate variables on the fly. The agent reads the exact CMYK, HSL, and RGB outputs directly in your file tree. You get clean, production-ready code without leaving your active workspace to search for a color picker.

Generate accessible UI themes in Agent mode

Contrast calculations are processed instantly by the `convert_color` tool in Cursor's Agent mode. The engine returns luminance and light/dark detection values directly to your editor. This allows your coding agent to write smart, contrast-compliant UI code. It automatically adjusts background colors based on the mathematical luminance of your foreground elements.

Map CSS names to design specs instantly

The `convert_color` tool parses legacy named colors like gainsboro or papayawhip inside your editor. It translates these names into modern HEX or HSL formats in milliseconds. Cursor uses this data to clean up your stylesheets. It replaces outdated color names with standardized variables in seconds, keeping your codebase clean.
