Shadcn Svelte MCP Server

A Model Context Protocol (MCP) server that provides AI assistants with comprehensive access to shadcn-svelte components, blocks, demos, and metadata. This server enables AI tools like Claude Desktop, Continue.dev, VS Code, Cursor, and other MCP-compatible clients to retrieve and work with shadcn-svelte components more effectively.

Note: This project is forked from Jpisnice/shadcn-ui-mcp-server - a fantastic MCP server for the original shadcn/ui React components. This fork adapts the functionality specifically for shadcn-svelte components.

🚀 Key Features

• Component Source Code: Get the latest shadcn-svelte component source code
• Component Demos: Access example implementations and usage patterns for Svelte components
• Blocks Support: Retrieve complete block implementations (dashboards, calendars, login forms, etc.) adapted for Svelte
• Metadata Access: Get component dependencies, descriptions, and configuration details for Svelte
• Directory Browsing: Explore the shadcn-svelte repository structure
• GitHub API Integration: Efficient caching and intelligent rate limit handling

📦 Quick Start

⚡ Using npx (Recommended)

The fastest way to get started - no installation required!

# Basic usage (rate limited to 60 requests/hour)
npx shadcn-svelte-mcp-server

# With GitHub token for better rate limits (5000 requests/hour)
npx shadcn-svelte-mcp-server --github-api-key ghp_your_token_here

# Short form
npx shadcn-svelte-mcp-server -g ghp_your_token_here

# Using environment variable
export GITHUB_PERSONAL_ACCESS_TOKEN=ghp_your_token_here
npx shadcn-svelte-mcp-server

🎯 Try it now: Run npx shadcn-svelte-mcp-server --help to see all options!

🔧 Command Line Options

shadcn-svelte-mcp-server [options]

🔑 GitHub API Token Setup

Why do you need a token?

• Without token: Limited to 60 API requests per hour
• With token: Up to 5,000 requests per hour
• Better reliability and faster responses

📝 Getting Your Token (2 minutes)

1. Go to GitHub Settings:

   • Visit GitHub Settings → Developer settings → Personal access tokens → Tokens (classic)
   • Or: GitHub Profile → Settings → Developer settings → Personal access tokens

2. Generate New Token:

   • Click "Generate new token (classic)"
   • Add a note: "shadcn-svelte MCP server"
   • Expiration: Choose your preference (90 days recommended)
   • Scopes: ✅ No scopes needed! (public repository access is sufficient)

3. Copy Your Token:

   • Copy the generated token (starts with ghp_)
   • ⚠️ Save it securely - you won't see it again!

🚀 Using Your Token

Method 1: Command Line (Quick testing)

npx shadcn-svelte-mcp-server --github-api-key ghp_your_token_here

Method 2: Environment Variable (Recommended)

# Add to your shell profile (~/.bashrc, ~/.zshrc, etc.)
export GITHUB_PERSONAL_ACCESS_TOKEN=ghp_your_token_here

# Then simply run:
npx shadcn-svelte-mcp-server

🐛 Troubleshooting

Common Issues

"Rate limit exceeded" errors:

# Solution: Add GitHub API token
npx shadcn-svelte-mcp-server --github-api-key ghp_your_token_here

"Command not found" errors:

# Solution: Install Node.js 18+ and ensure npx is available
node --version  # Should be 18+
npx --version   # Should work

Component not found:

# Check available components first
npx shadcn-svelte-mcp-server
# Then call list_components tool via your MCP client

Network/proxy issues:

# Set proxy if needed
export HTTP_PROXY=http://your-proxy:8080
export HTTPS_PROXY=http://your-proxy:8080
npx shadcn-svelte-mcp-server

Editor not recognizing MCP server:

# Verify the server is running
npx shadcn-svelte-mcp-server --help

# Check your editor's MCP configuration
# Ensure the command and args are correct

Debug Mode

Enable verbose logging:

# Set debug environment variable
DEBUG=* npx shadcn-svelte-mcp-server --github-api-key ghp_your_token
