6 tools offered to AI assistants

  • check_contrast · Check text/background contrast with WCAG 2 ratio, APCA Lc and a suggested fix that keeps the hue.
  • convert_color · Convert a hex color to RGB, HSL and OKLCH.
  • generate_harmony · Build a color harmony from a base color in OKLCH, mapped into the sRGB gamut.
  • roll_palette · Generate a 5-color palette that always contains a light/dark pair passing WCAG AA; optionally keep locked colors.
  • export_palette · Turn a list of colors into code for CSS, Tailwind, SwiftUI, Android, Flutter and other formats ColorPickr supports.
  • simulate_color_vision · Show how colors look with protanopia, deuteranopia, tritanopia or achromatopsia (Machado 2009).

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
