Audit component contrast inside Cursor

Let your AI agent verify your CSS values in real-time. The `check_color_contrast` tool calculates the ratio between your defined foreground and background variables. This allows you to catch accessibility bugs while you are writing the code. You get instant feedback on whether your styles pass WCAG guidelines.

Verify text on surfaces using Cursor

Use `check_text_on_pure_black` or `check_text_on_pure_white` to see how your labels look on standard backgrounds. These tools help you standardize your typography choices. It removes the need to switch between your editor and a browser-based tool. Your agent provides the results right where you work.

Automate accessibility checks in Cursor

The `check_danger_text_contrast` tool lets your agent audit your error state colors automatically. You can ensure that your feedback messages are always readable. This keeps your code clean and accessible without manual intervention. You just define the colors and let the agent do the audit.
