How Ux MCP Server works

What ux-mcp-server does

ux-mcp-server MCP server packages UX reference material and interactive analysis operations for use from an MCP client. Its knowledge resources cover areas such as WCAG 2.1 AA, Nielsen heuristics, UI patterns, responsive design, dark mode, error messages, Core Web Vitals, SEO, internationalization, forms, microcopy, typography, color, mobile interfaces, and framework patterns for React, Vue, and Angular.

The resource set also addresses e-commerce, information architecture, usability testing, progressive web apps, ethical design, SaaS, analytics, voice interfaces, AR/VR, AI and machine learning UX, haptics, healthcare, finance, neurodiversity, and web components. Resources use URI-style identifiers such as ux://accessibility/wcag and ux://performance/optimization.

Tools and capabilities

The server exposes 23 tools grouped around UX analysis, design content, testing, validation, and UI generation. Analysis operations can inspect code for accessibility, usability, performance, SEO, responsive behavior, and design-system concerns. Other tools check color contrast, recommend UI patterns, propose error messages and animations, and generate accessible HTML/CSS examples.

Design-oriented operations generate color palettes and typography scales, suggest microcopy, recommend form patterns, and select visualizations for data. Testing and validation tools can produce accessibility reports, suggest A/B test variants, assess information architecture, detect dark patterns, and calculate measures including SUS, NPS, CSAT, and task-success rates. UI generation includes ASCII wireframes and microinteraction recommendations.

Four predefined prompts provide structured workflows for an accessibility review, usability audit, design-system setup, and complete UX audit. The complete audit workflow is described as covering accessibility, usability, performance, responsive design, typography, color, forms, and SEO.

How it works

An MCP-compatible client starts the server and makes its resources, tools, and prompts available to an agent. The package can be installed globally with npm, run directly with npx, or built from a cloned source repository. The server is therefore suited to agent-assisted design review rather than a standalone visual design application.

The ux-mcp-server MCP server can be configured by giving a client the installed ux-mcp-server command. Source-based setups can instead invoke the built dist/index.js file with Node. Tool inputs and returned guidance depend on the operation selected by the client.

Setup and configuration

Install the published package with:

Terminal
npm install -g @elsahafy/ux-mcp-server

For a temporary run without a global installation, use:

Terminal
npx @elsahafy/ux-mcp-server

A source installation requires cloning the repository, running npm install, and executing npm run build. Claude Desktop and Cursor examples in the project configuration use the ux-mcp-server command. Claude Code can add the server with claude mcp add ux -- npx -y @elsahafy/ux-mcp-server.

Limitations and notes

Its capabilities are centered on supplied UX knowledge, generated recommendations, code-oriented checks, and workflow prompts. Results should be treated as review guidance; the material does not state that the tools replace human usability research or compliance review.
