Overview

AI-generated overview

Lets an assistant search Arc's React component library, read component docs and props, and fetch install commands or source for UI items.

What it does
Arc UI is a remote MCP endpoint for the Arc React component and block library. According to the README, it lets an assistant search, read docs and fetch source, and the registry description adds that it covers React components and blocks with motion plus search of docs, props and shadcn install commands. Free items are available without a key; an optional bearer token unlocks Pro source.
When to use it
Useful when building React interfaces and you want the assistant to look up Arc components, their props, and the exact shadcn CLI install command instead of guessing. Worth adding if your project already uses Arc or you plan to install its components.
Requirements
A remote Streamable HTTP endpoint; no local package or runtime is declared. The README states the components themselves need React 19 with TypeScript, Next.js App Router or Vite, the motion package, and the @/* import alias. An optional Authorization header with a bearer token from the provider's account page unlocks Pro source; free items work without it.
Before you install
The optional Authorization header carries a secret token; treat it as a credential and do not share it. Installing components runs the shadcn CLI, which writes files into your project and may add npm dependencies. Pro items are not in the free repository, so some fetched source may require the paid token.

Installation

In SourceWeft

  1. Open Arc UI in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Other MCP clients

Add this to your client's mcpServers config.

README

[Arc: React components and blocks with calm, crafted motion. Free and open source, install with shadcn.]

[License: MIT] [shadcn registry: @uiarc] [CI] [100 components] [22 blocks] [React 19]

Docs  ·  Components  ·  Install  ·  AI and MCP  ·  Pro

Arc is a library of React components and blocks with calm, physical motion. Every item is plain source you own: CSS modules on a small set of design tokens, Motion for animation, keyboard support, and a reduced motion path for every animation. Install anything with the shadcn CLI or copy the files by hand. It works in Next.js and Vite, with or without Tailwind. This repository holds the free, open source part: 100 components and 22 blocks, plus the design and motion tokens they share. Every one of them has a live preview at uiarc.dev.

Showcase

A few favorites, recorded live from uiarc.dev. Items marked Pro are part of Arc Pro and are not in this repository; everything else installs from here for free.

Contents

Install

Requirements

  • React 19 with TypeScript
  • Next.js (App Router) or Vite
  • motion for animation. Some items also use lucide-react or a Radix UI primitive; the CLI installs whatever an item needs.
  • The @/* import alias (Next.js and shadcn set it up by default)

No Tailwind is required. Arc styles are CSS modules that read CSS variables.

With the shadcn CLI

Register the @uiarc namespace once in components.json:

json
{  "registries": {    "@uiarc": "https://uiarc.dev/r/{name}.json"  }}

Then add items by name. Local dependencies, such as the components inside a block, come along automatically:

bash
npx shadcn@latest add @uiarc/button @uiarc/dialog

Every item also installs from its full URL, without touching components.json:

bash
npx shadcn@latest add https://uiarc.dev/r/button.json

Your first install adds arc-foundation (design and motion tokens). Import it once at the root of your app:

tsx
// app/layout.tsx (Next.js) or src/main.tsx (Vite)import "@/components/arc/foundation.css";
Setting up a new project

Next.js

bash
npx create-next-app@latest my-appcd my-appnpx shadcn@latest init

Accept the default @/* import alias.

Vite

bash
npm create vite@latest my-app -- --template react-tscd my-appnpx shadcn@latest init

Map @/* to src in tsconfig.json and vite.config.ts, as shadcn expects:

json
{  "compilerOptions": {    "baseUrl": ".",    "paths": { "@/*": ["./src/*"] }  }}
ts
import path from "node:path";import react from "@vitejs/plugin-react";import { defineConfig } from "vite";
export default defineConfig({  plugins: [react()],  resolve: { alias: { "@": path.resolve(__dirname, "./src") } },});

Copy and paste

  1. Install the shared packages: npm install motion lucide-react.
  2. Copy registry/foundation.css, registry/motion-tokens.ts and lib/motion-tokens.ts from this repository into the same paths under your @/ root, and import the CSS once at the root.
  3. Copy the item's folder from registry/components/<id>/ or registry/blocks/<id>/, keeping the path. Copied files keep this repository's layout and import each other through @/; the CLI install above rewrites that for you. Its public/r/<id>.json file lists every file and npm package it needs.

Each page on uiarc.dev also has a Manual tab with the exact files.

Usage

The CLI puts every file in an arc/ folder under the components alias in your components.json, for example components/arc/button/button.tsx, or src/components/arc/… in a src/ project or monorepo package. Arc files import each other with relative paths, so any alias setup works; move the arc/ folder as a whole if you want it elsewhere. Use them like any local component:

tsx
import { Button } from "@/components/arc/button/button";
export default function Page() {  return <Button>Save changes</Button>;}

The code is yours: edit it, rename it, move it. There is no runtime package to keep in sync.

Theming

Components read semantic tokens, never raw colors. Change a token in foundation.css (components/arc/foundation.css after a CLI install) and every component follows, in both themes.

TokenUsed for
--backgroundThe page behind everything
--surface, --surface-raised, --surface-mutedCards and inputs, floating layers, quiet fills
--foreground, --text-secondary, --text-mutedPrimary, supporting and hint text
--border, --border-subtle, --border-strongSeparators and edges
--accent, --accent-strong, --accent-subtleSelection, progress and helpful context
--success, --warning, --dangerStatus, always paired with a label
--radius-control, --radius-panel, --radius-surfaceControls, menus, cards
--font-display, --font-bodyGeist for headings, Inter for everything else
  • Dark mode: set data-theme="dark" on <html>. Dark values are tuned separately, not inverted.
  • Accent: set data-accent on <html> to neutral, violet, blue, green, amber, orange, coral or rose.
  • Motion: springs and durations live in lib/motion-tokens.ts (components/arc/lib/motion-tokens.ts after a CLI install). Every animation respects prefers-reduced-motion.

AI tools

Arc is built to be used from AI coding tools.

  • MCP server: https://uiarc.dev/api/mcp (Streamable HTTP, no key needed for free items). Search, read docs and fetch source from Claude Code, Cursor, VS Code or Codex.

    bash
    claude mcp add --transport http arc https://uiarc.dev/api/mcp
  • llms.txt: https://uiarc.dev/llms.txt for an index, llms-full.txt for everything in one file.

  • Markdown docs: every page has a Markdown version at /components/<id>/markdown.

Setup for each client is in the AI and MCP docs.

Troubleshooting

Cannot find module @/registry/...

Arc files import each other through the @/* alias. Map it to your project root in tsconfig.json (and in vite.config.ts for Vite). See Setting up a new project.

Components render without styles or colors

Import the tokens once at the root: import "@/registry/foundation.css";. If the file is missing, run npx shadcn@latest add @uiarc/arc-foundation.

The CLI says @uiarc is an unknown registry

Add the registries entry to components.json (see With the shadcn CLI), or install from the full URL: npx shadcn@latest add https://uiarc.dev/r/<id>.json.

Dark mode does not switch

Arc follows the data-theme attribute on <html>, not the dark class. Set data-theme="dark" before the page paints to avoid a flash of the light theme.

Using Vite: an item imports next/image or next/link

A few items use Next.js primitives: avatar, breadcrumb, changelog-feed, site-header, newsletter-signup. In Vite, replace Image with <img> and Link with <a>; the props map one to one for these uses.

Animations do not play

Arc honors the reduced motion setting of your operating system and swaps movement for simple fades. Turn it off to see the full motion, and make sure motion is installed.

The CLI asks to overwrite foundation.css

Every item lists the foundation as a dependency. If you have customized your tokens, answer no; the existing file keeps working.

How releases work

New free components and blocks ship regularly, a few at a time. Each release updates this repository, the @uiarc registry and the changelog together, so the code here always matches what the CLI installs. Watch or star the repository to hear about new items.

Arc Pro

Arc Pro adds 101 more components and blocks on top of this library: galleries like the Cover flow above, wallet and finance surfaces, richer charts, and complete product screens. They follow the same rules as everything here: plain source you own, both themes, keyboard support and a reduced motion path.

  • Source for every Pro component and block, installed with the same shadcn CLI through a personal token, or through the MCP server
  • Every new Pro release, plus fixes and updates to the pieces you already have
  • Yearly, or one payment for lifetime access. See pricing

Everything in this repository stays free and MIT licensed.
