Component Search

Search 21st.dev's registry of production-ready React components. Returns ranked results with code, previews, and install instructions.

/ork:component-search animated pricing table
/ork:component-search sidebar with collapsible sections
/ork:component-search dark mode toggle switch

How It Works

Step 0: Parse Query

QUERY = ""  # Component description

# 1. Create main task IMMEDIATELY
TaskCreate(subject="Component search: {QUERY}", description="Search 21st.dev registry", activeForm="Searching for {QUERY}")

# 2. Create subtasks for each phase
TaskCreate(subject="Parse query and detect project context", activeForm="Detecting project context")  # id=2
TaskCreate(subject="Search component registry", activeForm="Searching registry")                      # id=3
TaskCreate(subject="Present and deliver results", activeForm="Presenting results")                    # id=4

# 3. Set dependencies for sequential phases
TaskUpdate(taskId="3", addBlockedBy=["2"])  # Search needs project context first
TaskUpdate(taskId="4", addBlockedBy=["3"])  # Results need search done

# 4. Update status as you progress
TaskUpdate(taskId="2", status="in_progress")  # When starting
TaskUpdate(taskId="2", status="completed")    # When done — repeat for each subtask

# Detect project context for framework filtering
Glob("**/package.json")
# Read to determine: React version, Tailwind, shadcn/ui, styling approach

# Detect shadcn/ui style for result ranking
Glob("**/components.json")
# Read → "style" field (e.g., "radix-luma", "base-nova")
# Used to prefer components matching the project's visual language

Step 1: Search Registry

**If 21st-dev-magic MCP is available:**

# Use MCP tools to search the 21st.dev component registry
# Pass the natural language query
# The MCP handles semantic search and ranking

**If 21st-dev-magic is NOT available (fallback):**

# Fallback to web search
WebSearch("site:21st.dev {QUERY} React component")
# Or browse the registry
WebFetch("https://21st.dev", "Search for: {QUERY}")

**Alternative generation path — v0.app MCP (2026):** When the registry doesn't have a matching component, fall back to AI generation via the v0.app MCP server rather than WebFetch scraping:

# If @vercel/v0-mcp is available
# v0.app generates from the same query and can pin to shadcn style
# (e.g., luma / nova / lyra) via `shadcn apply` after download.

This is a **generation** path, not a registry search — results will not have view counts or stars. Prefer registry search when possible so you get battle-tested components; use v0.app only when the registry misses.

Step 2: Present Results

Show top 3 matches with:

• Component name and description
• Match relevance score
• Popularity (views/bookmarks)
• Framework compatibility
• Preview (if available)
• Install command

AskUserQuestion(questions=[{
  "question": "Which component to use?",
  "header": "Component",
  "options": [
    {"label": "{name_1} (Recommended)", "description": "{desc_1} — {views_1} views"},
    {"label": "{name_2}", "description": "{desc_2} — {views_2} views"},
    {"label": "{name_3}", "description": "{desc_3} — {views_3} views"},
    {"label": "None — generate from scratch", "description": "Build a custom component instead"}
  ],
  "multiSelect": false
}])

Step 3: Deliver Component

For the selected component: 1. Show the full source code 2. List dependencies (`npm install` commands) 3. Note any required peer dependencies (Radix, Motion, etc.) 4. Highlight customization points (props, tokens, slots)

Framework Compatibility

| Project Stack | Search Filter | Notes | |--------------|---------------|-------| | React + Tailwind | Default — best coverage | Most 21st.dev components | | React + CSS Modules | Filter non-Tailwind | Fewer results | | Next.js App Router | Prefer RSC-compatible | Check "use client" directives | | Vue / Svelte | Not supported | 21st.dev is R
