🚀 Quick Start

# Basic usage (60 requests/hour)
npx @jpisnice/shadcn-ui-mcp-server

# With GitHub token (5000 requests/hour) - Recommended
npx @jpisnice/shadcn-ui-mcp-server --github-api-key ghp_your_token_here

# Switch frameworks
npx @jpisnice/shadcn-ui-mcp-server --framework svelte
npx @jpisnice/shadcn-ui-mcp-server --framework vue
npx @jpisnice/shadcn-ui-mcp-server --framework react-native

🌐 SSE Transport & Docker Deployment

Run the server with Server-Sent Events (SSE) transport for multi-client support and production deployments:

Quick Start with SSE

# SSE mode (supports multiple concurrent connections)
node build/index.js --mode sse --port 7423

# Docker Compose (production ready)
docker-compose up -d

# Connect with Claude Code
claude mcp add --scope user --transport sse shadcn-mcp-server http://localhost:7423/sse

Transport Modes

• stdio (default) - Standard input/output for CLI usage
• sse - Server-Sent Events for HTTP-based connections
• dual - Both stdio and SSE simultaneously

Docker Examples

# Basic container
docker run -p 7423:7423 shadcn-ui-mcp-server

# With GitHub API token
docker run -p 7423:7423 -e GITHUB_PERSONAL_ACCESS_TOKEN=ghp_your_token shadcn-ui-mcp-server

# Docker Compose (recommended)
docker-compose up -d
curl http://localhost:7423/health

Environment Variables

• MCP_TRANSPORT_MODE - Transport mode (stdio|sse|dual)
• MCP_PORT - SSE server port (default: 7423 - SHADCN on keypad!)
• MCP_HOST - Host binding (default: 0.0.0.0)
• MCP_CORS_ORIGINS - CORS origins (comma-separated)
• GITHUB_PERSONAL_ACCESS_TOKEN - GitHub API token
