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.

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):

Prompt	What it asks your agent to do
`research_flow`	See how real apps handle a flow (onboarding, checkout, paywall…) and recommend one
`find_design_system`	Find real website design systems that fit your product and mood
`review_my_ui`	Compare a screen in your project with real apps and suggest fixes
`build_from_collection`	Start from references you saved on uxkin.com

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 uxkin@uxkin

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 page
opens where you log in and click Allow. To add only the server, put
mcp_config.json in ~/.gemini/config/mcp_config.json.

Use it as a Kiro power

In Kiro, open the Powers panel → Add Custom Power → Import power
from GitHub, and enter https://github.com/uxkin/agent. When Kiro asks
to authenticate uxkin, click Authenticate, log in to UXKIN and click
Allow.

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 where
you log in and click Allow.

What it sends

The skill runs locally and sends nothing. The MCP server receives only the
search text your agent sends (for example "onboarding for a meditation
app"), the result limit and your sign-in, and returns matching references
from uxkin.com. It doesn't read your code, files or conversation. See the
privacy policy.
