🎓 Level 1: Understanding MCP (1-2 hours)

Step 1.1: What is MCP? (15 minutes)

Goal: Understand the basic concept without technical jargon.

Think of MCP like this:

• Traditional AI: Like a smart person locked in a room with no internet or tools
• MCP-enabled AI: Like giving that person a universal remote control for your entire digital life

Real-world analogy:

🏠 Your House (Data & Tools)
├── 📁 Files and documents
├── 💾 Databases  
├── 🌐 Web services
├── 📧 Email systems
└── 🔧 Various tools

🎮 MCP = Universal Remote
├── 🔌 Connects to everything
├── 🔒 Secure access control
├── 📋 Standardized interface
└── 🔄 Works with any AI

✅ Check Your Understanding:

• Can you explain MCP to a friend in one sentence?
• Do you understand why AI needs external connections?

Step 1.2: Why MCP Matters (20 minutes)

Goal: See the bigger picture and real benefits.

Benefits: Clean, secure, reusable, future-proof

✅ Check Your Understanding:

• Can you list 3 problems MCP solves?
• Can you think of a use case in your own work?

Step 1.3: Key Concepts (25 minutes)

Goal: Learn the essential vocabulary.

The MCP Family:

🏠 MCP Host (Claude Desktop)
├── The "brain" that makes requests
├── Examples: Claude, IDEs, custom apps
└── Talks to servers through MCP protocol

🔧 MCP Server (The Helper)
├── Provides specific capabilities
├── Examples: file access, database queries, web search
└── Responds to host requests

📡 MCP Protocol (The Language)
├── How hosts and servers communicate
├── Standardized message format
└── Like HTTP for AI integrations

Core Capabilities:

• 🛠️ Tools: Actions the AI can perform (read file, send email, etc.)
• 📚 Resources: Data the AI can access (documents, database records, etc.)
• 💭 Prompts: Pre-written instructions for specific tasks
• 🤖 Sampling: Let servers request AI completions

✅ Check Your Understanding:

• Can you explain the difference between a host and server?
• Do you know what tools and resources are?

🔧 Level 2: Using MCP (2-3 hours)

Step 2.1: Set Up Your First MCP Experience (30 minutes)

Goal: Get Claude Desktop working with an MCP server.

What You’ll Need:

Step 2.2: Explore Different Server Types (45 minutes)

Goal: Try various servers to understand MCP’s versatility.

Server Buffet (Try 2-3 of these):

🗂️ File Management:

"filesystem": {
  "command": "npx",
  "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/safe/folder"]
}

Try: “Create a shopping list file”, “Organize my downloads folder”

• Start thinking about what you’d want to build

Step 2.3: Server Gallery Deep Dive (45 minutes)

Goal: Understand the ecosystem and find servers for your needs.

Official Server Categories:

📊 Data & Analytics:

• PostgreSQL, SQLite: Database access
• Memory: Persistent AI memory
• Use case: “Analyze my sales data”, “Remember customer preferences”

🔧 Developer Tools:

• GitHub, Git: Code repository access
• Sentry: Error monitoring
• Use case: “Review my recent commits”, “Check for production errors”

🌐 Web & Communication:

• Pick 3 servers that interest you
• Imagine how you’d use them in your work

👨‍💻 Level 3: Building Your Own (4-6 hours)

Step 3.1: Your First Custom Server (90 minutes)

Goal: Build a simple but functional MCP server from scratch.

Project: Personal Task Manager Server

What It Will Do:

• Add tasks to a list
• Mark tasks as complete
• List all tasks
• Clear completed tasks

Setup Your Environment:

# Create project folder
mkdir my-first-mcp-server
cd my-first-mcp-server

# Initialize Node.js project
npm init -y

# Install MCP SDK
npm install @modelcontextprotocol/sdk-typescript

Build the Server (Step by step):

1. Create the basic structure:

// server.ts
import { Server } from '@modelcontextprotocol/sdk-typescript';

const server = new Server({
  name: 'personal-tasks',
  version: '1.0.0'
});

// We'll add functionality here

server.start();

2. Add task storage:

// Simple in-memory storage
let tasks: Array<{id: number, text: string, done: boolean}> = [];
let nextId = 1;

3. Add your first tool:

server.tool('add-task', 'Add a new task', {
  text: { type: 'string', description: 'Task description' }
}, async (args) => {
  const task = {
    id: nextId++,
    text: args.text,
    done: false
  };
  tasks.push(task);
  return `Added task: ${task.text}`;
});

4. Test your server:

npx tsx server.ts

✅ Milestone Check:

• Server starts without errors
• You can add tasks through Claude
• You feel proud of your creation!

Step 3.2: Add More Features (90 minutes)

Goal: Enhance your server with additional capabilities.

Add More Tools:

// List all tasks
server.tool('list-tasks', 'Show all tasks', {}, async () => {
  if (tasks.length === 0) return 'No tasks yet!';
  
  return tasks.map(t => 
    `${t.id}. [${t.done ? '✅' : '⭐'}] ${t.text}`
  ).join('\n');
});

// Complete a task
server.tool('complete-task', 'Mark task as done', {
  id: { type: 'number', description: 'Task ID' }
}, async (args) => {
  const task = tasks.find(t => t.id === args.id);
  if (!task) return 'Task not found!';
  
  task.done = true;
  return `Completed: ${task.text}`;
});

// Clear completed tasks
server.tool('clear-completed', 'Remove all completed tasks', {}, async () => {
  const completedCount = tasks.filter(t => t.done).length;
  tasks = tasks.filter(t => !t.done);
  return `Cleared ${completedCount} completed tasks`;
});

Add Persistent Storage:

import fs from 'fs';

const TASKS_FILE = 'tasks.json';

// Load tasks on startup
function loadTasks() {
  try {
    const data = fs.readFileSync(TASKS_FILE, 'utf8');
    tasks = JSON.parse(data);
    nextId = Math.max(...tasks.map(t => t.id), 0) + 1;
  } catch {
    tasks = [];
    nextId = 1;
  }
}

// Save tasks after changes
function saveTasks() {
  fs.writeFileSync(TASKS_FILE, JSON.stringify(tasks, null, 2));
}

✅ Enhancement Goals:

• All CRUD operations work
• Tasks persist between restarts
• Error handling is graceful

Step 3.3: Real-World Integration (120 minutes)

Goal: Connect your server to real data or services.

Choose Your Adventure:

Option A: File-Based Notes

// Add note-taking capability
server.tool('save-note', 'Save a note to file', {
  title: { type: 'string' },
  content: { type: 'string' }
}, async (args) => {
  const filename = `notes/${args.title.replace(/\s+/g, '-')}.md`;
  fs.writeFileSync(filename, args.content);
  return `Note saved: ${filename}`;
});

Option B: API Integration

// Weather integration example
server.tool('get-weather', 'Get current weather', {
  city: { type: 'string' }
}, async (args) => {
  const response = await fetch(
    `https://api.openweathermap.org/data/2.5/weather?q=${args.city}&appid=${API_KEY}`
  );
  const data = await response.json();
  return `Weather in ${args.city}: ${data.weather[0].description}`;
});

Option C: Database Connection

import sqlite3 from 'sqlite3';

// Simple database integration
server.tool('query-db', 'Query database', {
  query: { type: 'string' }
}, async (args) => {
  return new Promise((resolve, reject) => {
    db.all(args.query, (err, rows) => {
      if (err) reject(err);
      else resolve(JSON.stringify(rows, null, 2));
    });
  });
});

✅ Integration Success:

• Server connects to external data/service
• Error handling for network issues
• You see the real power of MCP!
