Validate Interaction States in Code

The `validate_uiux_excellence` tool forces you to account for eight states on every interactive element—default, hover, focus-visible, active/pressed, loading, success, error, and disabled. This prevents broken components. When the AI generates working code using Cursor, this server ensures that when a button is clicked, the resulting API response (not just mock data) validates all expected states.

Establish Semantic Visual Hierarchy

It fixes 'Flat Decoration' by forcing you to use elevation levels 0-5 with specific shadow tokens. This gives your UI proper depth, making it obvious which element is the most important thing on the screen. Cursor uses this MCP Server to ensure that code generating a critical alert (Level 5) always has distinct visual properties from standard content (Level 1).

Check for WCAG AAA Compliance in Code

The tool verifies accessibility requirements, ensuring every image gets alt text and all icon buttons have `aria-label` attributes. It also enforces a minimum color contrast of 4.5:1. This means the code you write with Cursor will pass rigorous screen reader testing (NVDA/VoiceOver) right out of the gate.

Setup guide

Set up UI/UX Excellence Prover MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the UI/UX Excellence Prover MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent UI/UX Excellence Prover transactions." If the MCP tools are loaded correctly, Cursor will call the UI/UX Excellence Prover tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about UI/UX Excellence Prover MCP in Cursor

It acts as a live design safety net. When your AI client calls `validate_uiux_excellence`, it validates that the generated code adheres to modern, human-centric design standards before you even commit.

Yes. It rigorously tests components by checking microinteractions like touch targets (minimum 44×44px) and ensuring feedback is delivered within a strict 100ms time limit.

It mandates user agency. The server checks that no design element tricks the user, ensuring all opt-in/opt-out options have equal visual weight and clarity.

It demands purposeful motion. The server ensures that any animation is tied to a function—it must explain, guide, or confirm—and provides necessary fallbacks for reduced motion.

The server validates Design Metadata. It inspects how your code handles visual structure and user interaction points, ensuring everything is built on a consistent 8px grid.
