Enforce WCAG AAA Standards Across the Team

This MCP Server ensures that every developer on your team follows strict accessibility rules, including alt text for all images and `aria-label` tags for icon buttons. It verifies color contrast is always 4.5:1 or better. Because this setup is committed via `.vscode/mcp.json`, the entire organization uses these AAA checks automatically when Copilot Chat runs an agent task.

Manage Depth and Affordance Semantics

The `validate_uiux_excellence` tool solves ambiguity by forcing semantic depth using elevation levels 0-5. It makes sure that a critical alert (Level 5) isn't visually indistinguishable from a background card (Level 1). This consistency is key for large teams, guaranteeing everyone knows which element to click without needing extra context.

Validate Code Against User Rhythm

It checks your design's visual rhythm by verifying both spacing and typography. The server requires a modular typographic scale with at least a 3:1 ratio between heading size and body text. Copilot can use this MCP Server to flag inconsistent padding or headings that are too close to the body copy, keeping the whole team aligned on structure.

Common questions about UI/UX Excellence Prover MCP in VS Code Copilot

It standardizes design quality across all repositories. Since it's configured in `.vscode/mcp.json`, every developer gets access to the same, high bar for visual and interactive excellence.

Yes. It requires that any animation used must be purposeful—it has to explain or confirm something—and it enforces 60fps spring physics, making the user experience predictable.

It strictly audits for 'roach motel' designs. The server ensures that options are never pre-checked and that the visual weight given to opting in versus opting out is always equal.

It mandates 8 states per interactive element. This means it checks beyond just 'default' and 'hover,' ensuring you account for loading, success, error, and disabled states in your code.

The server validates Design Metadata. It analyzes how different components are structured within the codebase, checking for things like consistent padding and meaningful whitespace ratios.
