Why

Ask a coding agent for a settings screen, a paywall or a landing page and it fills every gap with the most common choices: the same gradients, card grids and vague copy as everyone else. UXKIN gives it something better to work from: how real, shipped products handle the same screen or flow, and the actual colors, type and components of real websites.

Quick start

| What | For | Cost | | :- | :- | :- | | `no-ui-slop` skill | Rules that keep your agent from shipping generic, AI-looking UI | Free, no account | | `build-ui` skill | A step-by-step workflow for new screens, dashboards, polish, simplifying and reviews that ends with a checked result | Free, no account | | `ios-screens` skill | iPhone screens that feel native: navigation, sheets, Dynamic Type, dark mode, permissions | Free, no account | | `design-md` skill | Writes a DESIGN.md for your project from what it really uses, so every new screen matches | Free, no account | | `ui-from-screenshot` skill | Turns a screenshot or mockup into matching UI with your own components, then compares side by side | Free, no account | | `ui-states` skill | Builds the states agents forget: empty, loading, error, offline, long content | Free, no account | | `uxkin-research` skill | How your agent finds and compares real apps, flows and design systems before it designs | UXKIN plan to search (the skill itself is MIT) | | UXKIN MCP server | Your agent searches real screens, journeys and design systems while it builds | UXKIN plan | | UI Check GitHub Action | Flags dead buttons, missing states, one-off colors and accessibility basics in every pull request | Free | | AI Slop Detector | See how AI-generated your website looks, and what to change | Free | | UXKIN for Figma | Search UXKIN, place screens and whole flows on the canvas, import a site's colors and type | Coming soon to Figma Community |

1. Install the free skills

npx skills add uxkin/agent

That installs all seven, or copy them into your agent's skills folder:

• skills/no-ui-slop: how to build UI that fits the product. Works on its own, with no account; with the UXKIN server connected, it also tells your agent when to look up a real reference.
• skills/uxkin-research: how to research before designing: search the UXKIN library in plain words, open whole journeys, compare several apps and report what they have in common.
• build-ui: a plan for each kind of UI job (new screen, dashboard, polish, simplify, review), finished by rendering at phone and desktop sizes, fixing and checking again.
• ios-screens: native iPhone UI in SwiftUI, UIKit, React Native, Expo or Flutter, checked on small and large iPhones, light and dark.
• design-md: reads your project and writes (or updates) its DESIGN.md: colors with roles, type scale, spacing, components and rules for agents.
• ui-from-screenshot: builds a screenshot or mockup with your own components, then compares the result with the image and fixes the differences.
• ui-states: finds and builds every state of a screen (first use, empty, loading, error, offline, success) and checks each one.

All of them work on their own; with the UXKIN server connected they can also look up real screens, flows and design systems. The plugins below include no-ui-slop and uxkin-research; the other five install with the command above (they live in .agents/skills).

2. Connect the UXKIN MCP server

The server is hosted at https://uxkin.com/mcp (Streamable HTTP). Most apps sign in with your UXKIN account: no token to copy.

| App | How | | :- | :- | | Claude (web, desktop, mobile) | Open UXKIN in Claude's directory, click Connect, log in and click Allow | | Claude Code | claude mcp add --scope user --transport http uxkin https://uxkin.com/mcp, then /mcp → uxkin → Authenticate | | Cursor | One-click install on uxkin.com/cursor-ui-design, then Login next to uxkin | | Codex | codex mcp add uxkin --url https://uxkin.com/mcp, then codex mcp login uxkin (or install the Codex plugin) | | GitHub Copilot (VS Code) | Command Palette → MCP: Add Server → HTTP → https://uxkin.com/mcp, then sign in when asked (guide) | | Lovable, Bolt, Devin Desktop | Add a custom MCP server with the URL above (Lovable, Bolt, Devin Desktop / Windsurf) | | Any other MCP client | Add https://uxkin.com/mcp and sign in, or follow the setup at uxkin.com/docs |

Searching needs a UXKIN plan (Monthly or Lifetime). You can disconnect any app from your account.

Try it

Once connected, ask your agent things like:

• *"Use UXKIN to find onboarding flows from real meditation apps, and tell me what they have in common."*
• *"Use UXKIN to show me how real apps handle cancelling a subscription, then improve my cancel screen."*
• *"Find a light, minimal SaaS design system on UXKIN and build my landing page hero in that style."*
• *"Before you build the paywall, look up three real paywalls on UXKIN and say which decisions you're taking from each."*

Tools

| Tool | Returns | | :- | :- | | find_ui_references | Real iOS app screens, user journeys (multi-screen flows like onboarding or cancelling a subscription) and websites | | find_ui_materials | Design systems from real websites: colors with their roles, typography, components, and the full DESIGN.md for the top match | | get_journey | Every screen of one journey, in order | | list_collections / get_collection | The references you saved into collections on uxkin.com |

All tools are read-only.

It also offers ready-made prompts your app can show as commands (in Claude Code: /mcp__uxkin__research_flow and so on):

What's in this repository

• The `no-ui-slop` and `uxkin-research` skills (skills). The five other skills are installed separately with npx skills add uxkin/agent.
• The UXKIN plugin for Claude (.claude-plugin), Cursor (.cursor-plugin) and Codex (.codex-plugin), the Kiro power (POWER.md), the Google Antigravity plugin (plugin.json) and the Gemini CLI extension (gemini-extension.json): the skill and the MCP server in one install.
• The MCP server listing (server.json), published to the official MCP Registry.
• UXKIN's own design system (DESIGN.md): UXKIN exports a DESIGN.md for every website in its library, and UXKIN itself is built from one. Hand it to your agent to see the format in action.
• Where UXKIN is listed (DISTRIBUTION.md): every registry, app store and directory, and where each one stands.
• Examples (examples): config files for each app, project instructions for your AGENTS.md or CLAUDE.md, example prompts, and worked examples (account deletion, subscription cancellation, mobile onboarding) showing what an agent does differently with UXKIN.

Use it as a Claude plugin

One install adds the skill and the UXKIN server. The skill works right away; to search the library, connect the server (Claude opens a UXKIN page where you log in and click Allow). In Claude Code, type /mcp, pick uxkin and choose Authenticate.

In Claude Code you can also add it from GitHub directly:

claude plugin marketplace add uxkin/agent

claude plugin install uxk
