chakra-ui

name	chakra-ui
description	Chakra UI — accessible React components. v2/v3 APIs incompatible.

Detection Signals

• @chakra-ui/react in package.json
• ChakraProvider (v2) or Provider (v3) at app root
• @emotion/react and @emotion/styled dependencies
• Style props on components (p, m, color, bg, fontSize as JSX props)
• extendTheme import (v2) or createSystem import (v3)

MCP Setup

No official MCP server is available for Chakra UI.

Reference the docs for the correct version:

• v2: v2.chakra-ui.com
• v3: chakra-ui.com

Configure a documentation search MCP if your CLI supports one.

Version Detection — Do This First

# Check installed version before writing any code
cat package.json | grep "@chakra-ui/react"

Signal	Version
extendTheme, ChakraProvider	v2
createSystem, Provider	v3

v2 and v3 APIs are incompatible. Do not mix patterns. Confirm version before writing a single line.

Core Concepts

Concept	Detail
ChakraProvider / Provider	Wraps app — required; components without it render unstyled or throw
Style props	CSS properties as component props: p={4}, color="gray.700", bg="blue.50"
Color tokens	Semantic scale: blue.500, gray.100, red.600 — not raw hex
Responsive values	Array syntax (mobile-first): <Box fontSize={['sm', 'md', 'lg']}>
useColorMode()	Toggle dark/light; useColorModeValue('light-val', 'dark-val') for tokens
useTheme()	Access theme tokens in component logic

Component Patterns (v2)

// Provider at root
import { ChakraProvider } from '@chakra-ui/react'
const theme = extendTheme({
  colors: { brand: { 500: '#3182CE' } },
  fonts: { heading: 'Inter, sans-serif' },
})
<ChakraProvider theme={theme}><App /></ChakraProvider>

// Style props — always use tokens, not hex
<Box p={4} bg="gray.50" borderRadius="md" shadow="sm">
  <Text color="gray.700" fontSize="sm" fontWeight="medium">Content</Text>
</Box>

// Responsive — array is mobile-first breakpoints
<Stack direction={['column', 'row']} spacing={4} />

// Dark mode
<Box bg={useColorModeValue('', '')}>

Critical Rules

• Check v2 vs v3 first — APIs are incompatible; generating v2 code for a v3 project breaks the app
• Provider must wrap everything — components outside it silently use no theme
• Use color tokens (gray.500) not hex values — tokens adapt to dark/light mode automatically
• useColorModeValue() for dark mode — never hardcode separate color values for each mode
• Prefer Stack/HStack/VStack over manual Flex + flexDirection — clearer intent, less props
• v2: don't import from sub-packages — import from @chakra-ui/react, not @chakra-ui/button; tree-shaking handles the rest
