🚀 MCP Lab Workshop

Learn Model Context Protocol (MCP) with Cloudflare Workers

---

🎯 What is This?

An interactive workshop for SE interns to learn about Model Context Protocol (MCP) servers. Deploy a live dashboard app that can be controlled in real-time via MCP tools.

What You'll Build

1. 🎨 Interactive Dashboard - A beautiful dark-themed web app with real-time stats
2. 🔧 MCP Server - A fully functional MCP server with 8 tools to control the dashboard
3. 📡 Real-time Connection - Watch the dashboard update live as you call MCP tools

---

✨ Features

Demo App

• 🌙 Dark-themed beautiful UI with Cloudflare branding
• 📊 Live statistics that update in real-time
• 🎛️ Feature toggles (Analytics, Notifications, Dark Mode, Animations)
• 📡 Activity feed showing all MCP actions
• ⚡ Server-Sent Events for instant updates

MCP Server

• 🛠️ 8 MCP Tools for controlling the dashboard
• 🔓 No authentication required - perfect for learning
• 🌍 Edge deployed - runs on Cloudflare's global network
• 📦 KV storage for state management

🚀 Quick Deploy

One-Click Deploy

Click the button above to deploy to your Cloudflare account:

The deploy process will:

1. ✅ Clone the repo to your GitHub
2. ✅ Create a KV namespace automatically
3. ✅ Deploy TWO workers: mcp-demo-app (dashboard) and mcp-server (MCP tools)
4. ✅ Give you live URLs instantly

Important: The deployment creates two separate workers. Make sure both are deployed successfully!

Manual Deploy

If you prefer to deploy manually:

# Clone the repo
git clone https://github.com/MattDMitch/mcp-lab-workshop.git
cd mcp-lab-workshop

# Install dependencies
npm install

# Login to Cloudflare
npx wrangler login

# Run deploy script (creates KV namespace and deploys both workers)
npm run deploy

This will deploy:

• ✅ mcp-demo-app - The monitoring dashboard UI
• ✅ mcp-server - The MCP tools server

---

🎮 Using the MCP Server

Once deployed, you'll get ONE worker with multiple endpoints:

• Dashboard: https://YOUR-WORKER-NAME.YOUR-SUBDOMAIN.workers.dev/
• MCP Server: https://YOUR-WORKER-NAME.YOUR-SUBDOMAIN.workers.dev/mcp

Both the dashboard and MCP server run in the same worker using path-based routing

Connect to MCP Server

Add the MCP server to your OpenCode or MCP client:

{
  "mcpServers": {
    "demo": {
      "url": "https://REPO-NAME-mcp.YOUR-SUBDOMAIN.workers.dev"
    }
  }
}
