Perplexity

Automate dark pattern detection.

The `validate_uiux_excellence` tool runs in the terminal to check for design patterns that trick users. It flags issues like pre-checked options or giving unequal visual weight to opt-in versus opt-out choices. This means your CI/CD pipeline can verify that checkout flows are truly transparent and unbiased before deployment.

Validate all motion using headless checks.

You use this tool in a script to ensure any component being deployed adheres to purposeful animation rules. It forces checking for spring physics, 60fps consistency, and proper `prefers-reduced-motion` fallbacks. This confirms that even without a GUI running the test, the underlying code structure supports excellent motion design.

Verify accessibility compliance via script.

The tool validates core accessibility standards like WCAG 2.2 AAA directly from the command line. It checks for `aria-label` existence and ensures that all interactive elements are keyboard accessible. This gives DevOps engineers a reliable, non-GUI method to verify crucial user experience requirements.

Common questions about UI/UX Excellence Prover MCP in Claude Code

It acts as a dedicated quality gate in your CI/CD pipeline. Your shell script can call this MCP Server after generating static component markup, ensuring the output is polished and compliant.

It processes design specifications, structural definitions (like grid sizes or spacing rules), and accessibility metadata to generate a pass/fail report for the component build.

Yes. You can run it against generated markup that includes microinteractions, checking if all eight states (loading, success, error) are accounted for and defined.

It checks the code's output against spacing rules—specifically enforcing macro whitespace contrast between sections. This confirms structural hierarchy is maintained even in headless deployments.

The server validates structural and visual design data, including the presence of opt-in/opt-out controls. This confirms that user agency is maintained by avoiding dark patterns.
