UXKIN: real UI references for AI coding agents
Search real iOS app screens, complete user journeys and website design systems from Claude, Claude Code, Cursor, Codex, GitHub Copilot and any MCP client, so the UI your agent builds looks like a real product instead of AI defaults.
63,589 iOS screens from 303 apps · 1,991 user journeys · 1,288 website design systems, each with a DESIGN.md
Website · Docs · Claude directory · Pricing · Support
Why
Ask a coding agent for a settings screen, a paywall or a landing page andit fills every gap with the most common choices: the same gradients, cardgrids and vague copy as everyone else. UXKIN gives it something better towork from: how real, shipped products handle the same screen or flow, andthe actual colors, type and components of real websites.

1. Install the free no-ui-slop skill
npx skills add uxkin/agent
Or copy skills/no-ui-slop/SKILL.md intoyour agent's skills folder. It works on its own, with no account. Withthe UXKIN server connected, it also tells your agent when to look up areal reference.
2. Connect the UXKIN MCP server
The server is hosted at https://uxkin.com/mcp (Streamable HTTP). Mostapps 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 | Use the setup prompt from uxkin.com (a token sent as Authorization: Bearer <token>) |
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."

What's in this repository
- The
no-ui-slopskill (skills/no-ui-slop). - The UXKIN plugin for Claude (
.claude-plugin),Cursor (.cursor-plugin) and Codex(.codex-plugin), the Google Antigravity plugin(plugin.json) and the Gemini CLI extension(gemini-extension.json): the skill and the MCPserver in one install. - The MCP server listing (
server.json), published to theofficial MCP Registry. - UXKIN's own design system (
DESIGN.md): UXKIN exports aDESIGN.md for every website in its library, and UXKIN itself is built fromone. Hand it to your agent to see the format in action. - Where UXKIN is listed (
DISTRIBUTION.md): everyregistry, app store and directory, and where each one stands. - Examples (
examples): config files for each app, projectinstructions for yourAGENTS.mdorCLAUDE.md, and example prompts.
Use it as a Claude plugin
One install adds the skill and the UXKIN server. The skill works rightaway; to search the library, connect the server (Claude opens a UXKIN pagewhere you log in and click Allow). In Claude Code, type /mcp, pickuxkin and choose Authenticate.
Use it as a Cursor plugin
After installing, click Login next to uxkin in Cursor's MCP settings,log in to UXKIN and click Allow.
Use it as a Codex plugin
codex plugin marketplace add uxkin/agent
codex plugin add uxkin@uxkin
codex mcp login uxkin
The last command opens a UXKIN page where you log in and click Allow.
Use it as a Google Antigravity plugin
git clone https://github.com/uxkin/agent uxkin
agy plugin install ./uxkin
Then type /mcp, pick uxkin and choose Authenticate: a UXKIN pageopens where you log in and click Allow. To add only the server, putmcp_config.json in ~/.gemini/config/mcp_config.json.
Use it as a Gemini CLI extension
gemini extensions install https://github.com/uxkin/agent
Then start Gemini CLI and type /mcp auth uxkin: a UXKIN page opens whereyou log in and click Allow.
What it sends
The skill runs locally and sends nothing. The MCP server receives only thesearch text your agent sends (for example "onboarding for a meditationapp"), the result limit and your sign-in, and returns matching referencesfrom uxkin.com. It doesn't read your code, files or conversation. See theprivacy policy.
