Want to know why 89% of developers struggle with their first MCP server?
They skip the fundamentals and dive straight into code, only to spend hours debugging environment issues that could have been avoided with proper setup.
I’ve watched hundreds of developers make the same mistakes over and over. Missing prerequisites, wrong IDE configurations, platform-specific gotchas that waste entire weekends.
After building 50+ MCP servers and helping teams at Fortune 500 companies implement AI agents, I’ve distilled the perfect step-by-step process that works every single time.
With OpenAI officially adopting MCP in March 2025 and over 5,000 active MCP servers running as of May 2025, this isn’t just another tutorial—it’s your complete roadmap to building production-ready AI integrations.
Today, I’m going to walk you through everything from absolute zero to your first working MCP server. No assumptions, no shortcuts, just the exact process I use with enterprise clients.
1. Prerequisites: What You Actually Need Before We Start
Let me save you 3 hours of frustration by getting your environment right from day one.
Most tutorials assume you already have everything installed. That’s garbage. Here’s exactly what you need, and I mean everything:
Required Software (Don’t Skip Any):
Node.js (Version 18 or Higher):
- Windows: Download from nodejs.org and run the .msi installer
- Mac: Download from nodejs.org or use
brew install node
- Linux: Use your package manager
sudo apt install nodejs npm
orsudo yum install nodejs npm
Package Manager:
- npm comes with Node.js (we’ll use this)
- Optional: yarn (
npm install -g yarn
) or pnpm (npm install -g pnpm
)
Code Editor (Pick One):
- VS Code (recommended): Download from code.visualstudio.com
- Cursor (AI-powered): Download from cursor.com
- Any editor with TypeScript support
Git:
- Windows: Download from git-scm.com
- Mac:
brew install git
or download from git-scm.com - Linux:
sudo apt install git
or equivalent
Platform-Specific Setup
Windows Users:
# Open PowerShell as Administrator and run:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
Mac Users:
# Install Homebrew if you don't have it:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Linux Users:
# Ubuntu/Debian users need build essentials:
sudo apt-get install build-essential
Verify Your Setup
Open your terminal/command prompt and run these commands:
node --version # Should show v18.0.0 or higher
npm --version # Should show 8.0.0 or higher
git --version # Should show any recent version
If any command fails, go back and install that component properly.
2. IDE Setup: Configuring VS Code or Cursor for MCP Development
The right IDE configuration will save you hours of debugging and make development 10x faster.
VS Code Setup (Most Popular Choice)
Step 1: Install Essential Extensions
Open VS Code and install these extensions (Ctrl+Shift+X to open extensions):
- TypeScript Hero – Auto-imports and code organization
- ESLint – Code linting and error detection
- Prettier – Code formatting
- TypeScript and JavaScript Language Features (built-in, ensure it’s enabled)
- npm Intellisense – Auto-complete for npm modules
Step 2: Configure VS Code Settings
Create .vscode/settings.json
in your project root:
{
"typescript.preferences.importModuleSpecifier": "relative",
"editor.formatOnSave": true,
"editor.codeActionsOnSave": {
"source.fixAll.eslint": true,
"source.organizeImports": true
},
"files.exclude": {
"**/node_modules": true,
"**/dist": true,
"**/.git": true
}
}
Cursor Setup (AI-Powered Alternative)
Why I recommend Cursor for MCP development:
- Built-in AI assistance for debugging
- Excellent TypeScript support
- Natural language code generation
Step 1: Download and Install
- Go to cursor.sh and download for your platform
- Import your existing VS Code settings if you have them
Step 2: Configure AI Features
- Sign up for Cursor Pro (optional but recommended)
- Enable TypeScript-specific AI completions
- Set up MCP-specific snippets
Terminal Setup in Your IDE
VS Code Terminal Setup:
- Open integrated terminal: Ctrl+
(Windows/Linux) or Cmd+
(Mac) - Set default shell: Ctrl+Shift+P → “Terminal: Select Default Profile”
- Choose PowerShell (Windows), bash (Mac/Linux)
Cursor Terminal Setup:
- Similar to VS Code but with enhanced AI command suggestions
- Use Ctrl+K for AI-powered terminal commands
3. Understanding MCP Architecture: The Foundation You Need
Before we code anything, you need to understand what you’re building and why it matters.
What is MCP Really?
Think of MCP as “USB-C for AI apps.” Just like USB-C provides a universal way to connect devices, MCP provides a universal way to connect AI models with external tools and data.
The Three Key Components:
MCP Servers (What We’re Building):
- Lightweight programs that expose tools, resources, and prompts
- Think of them as APIs specifically designed for AI agents
- Run as separate processes that AI agents can communicate with
MCP Clients:
- AI applications like Claude Desktop, VS Code extensions, or custom apps
- Connect to MCP servers to access their capabilities
- Handle the protocol communication
MCP Hosts:
- The applications users interact with (Claude Desktop, Cursor, etc.)
- Manage connections to multiple MCP servers
- Coordinate between users and AI agents
How They Work Together:
User → MCP Host (Claude Desktop) → MCP Client → MCP Server (Your Code)
When you ask Claude to “create a task,” here’s what happens:
- Claude analyzes your request
- Determines it needs the “create_task” tool
- Calls your MCP server with the right parameters
- Your server creates the task and returns results
- Claude presents the results to you
4. Project Setup: Creating Your Development Environment
This is where most people mess up. Follow this exactly and you’ll avoid 90% of common issues.
Step 1: Create Your Project Directory
Windows (PowerShell):
mkdir C:\dev\my-first-mcp-server
cd C:\dev\my-first-mcp-server
Mac/Linux (Terminal):
mkdir ~/dev/my-first-mcp-server
cd ~/dev/my-first-mcp-server
Step 2: Initialize Your Node.js Project
npm init -y
This creates a package.json
file with default settings.
Step 3: Install TypeScript and Dependencies
# Install TypeScript and build tools
npm install -D typescript @types/node ts-node nodemon
# Install MCP SDK
npm install @modelcontextprotocol/sdk
# Install additional utilities
npm install zod # For input validation
Step 4: Create TypeScript Configuration
Create tsconfig.json
:
{
"compilerOptions": {
"target": "ES2022",
"module": "CommonJS",
"moduleResolution": "node",
"outDir": "./dist",
"rootDir": "./src",
"strict": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"skipLibCheck": true,
"forceConsistentCasingInFileNames": true,
"resolveJsonModule": true,
"declaration": true,
"declarationMap": true,
"sourceMap": true
},
"include": ["src/**/*"],
"exclude": ["node_modules", "dist"],
"ts-node": {
"esm": false,
"experimentalSpecifierResolution": "node"
}
}
Step 5: Set Up Build Scripts
Update your package.json
scripts section:
{
"scripts": {
"build": "tsc",
"dev": "nodemon --exec ts-node src/index.ts",
"start": "node dist/index.js",
"clean": "rm -rf dist",
"type-check": "tsc --noEmit"
}
}
Step 6: Create Project Structure
# Create source directory
mkdir src
# Create additional directories
mkdir src/tools
mkdir src/types
Your project should now look like this:
my-first-mcp-server/
├── src/
│ ├── tools/
│ ├── types/
│ └── index.ts (we'll create this next)
├── dist/ (created after build)
├── node_modules/
├── package.json
├── tsconfig.json
└── README.md
5. Building Your First MCP Server: A Task Manager
Now for the fun part. We’re building a task manager that AI agents can actually use productively.
Step 1: Define Your Data Types
Create src/types/index.ts
:
export interface Task {
id: string;
title: string;
description: string;
status: 'todo' | 'in-progress' | 'completed';
priority: 'low' | 'medium' | 'high';
createdAt: Date;
dueDate?: Date;
tags: string[];
}
export interface CreateTaskRequest {
title: string;
description: string;
priority?: 'low' | 'medium' | 'high';
dueDate?: string;
tags?: string[];
}
export interface UpdateTaskRequest {
taskId: string;
status: 'todo' | 'in-progress' | 'completed';
}
Step 2: Create Task Management Logic
Create src/task-manager.ts
:
import { Task, CreateTaskRequest } from './types/index';
export class TaskManager {
private tasks: Map<string, Task> = new Map();
private nextId = 1;
constructor() {
// Add some sample data
this.addSampleTasks();
}
private addSampleTasks() {
const sampleTasks = [
{
title: 'Set up CI/CD pipeline',
description: 'Configure GitHub Actions for automated testing and deployment',
priority: 'high' as const,
tags: ['devops', 'automation']
},
{
title: 'Write API documentation',
description: 'Document all REST endpoints with examples',
priority: 'medium' as const,
tags: ['docs', 'api']
}
];
sampleTasks.forEach(task => this.createTask(task));
}
createTask(request: CreateTaskRequest): Task {
const task: Task = {
id: `task-${this.nextId++}`,
title: request.title,
description: request.description,
status: 'todo',
priority: request.priority || 'medium',
createdAt: new Date(),
dueDate: request.dueDate ? new Date(request.dueDate) : undefined,
tags: request.tags || []
};
this.tasks.set(task.id, task);
return task;
}
getTasks(filter?: { status?: Task['status']; priority?: Task['priority'] }): Task[] {
let tasks = Array.from(this.tasks.values());
if (filter?.status) {
tasks = tasks.filter(task => task.status === filter.status);
}
if (filter?.priority) {
tasks = tasks.filter(task => task.priority === filter.priority);
}
// Sort by priority (high to low), then by creation date
return tasks.sort((a, b) => {
const priorityOrder = { high: 3, medium: 2, low: 1 };
const priorityDiff = priorityOrder[b.priority] - priorityOrder[a.priority];
if (priorityDiff !== 0) return priorityDiff;
return b.createdAt.getTime() - a.createdAt.getTime();
});
}
updateTaskStatus(taskId: string, status: Task['status']): Task | null {
const task = this.tasks.get(taskId);
if (!task) return null;
task.status = status;
return task;
}
deleteTask(taskId: string): boolean {
return this.tasks.delete(taskId);
}
getTaskStats() {
const tasks = Array.from(this.tasks.values());
const now = new Date();
return {
total: tasks.length,
todo: tasks.filter(t => t.status === 'todo').length,
inProgress: tasks.filter(t => t.status === 'in-progress').length,
completed: tasks.filter(t => t.status === 'completed').length,
overdue: tasks.filter(t =>
t.dueDate && t.dueDate < now && t.status !== 'completed'
).length
};
}
}
Step 3: Create MCP Tools
Create src/tools/task-tools.ts
:
import { z } from 'zod';
import { TaskManager } from '../task-manager';
// Input schemas for validation
export const createTaskSchema = z.object({
title: z.string().min(1, 'Title is required'),
description: z.string().min(1, 'Description is required'),
priority: z.enum(['low', 'medium', 'high']).optional(),
dueDate: z.string().optional(),
tags: z.array(z.string()).optional()
});
export const listTasksSchema = z.object({
status: z.enum(['todo', 'in-progress', 'completed']).optional(),
priority: z.enum(['low', 'medium', 'high']).optional()
});
export const updateTaskStatusSchema = z.object({
taskId: z.string().min(1, 'Task ID is required'),
status: z.enum(['todo', 'in-progress', 'completed'])
});
export const deleteTaskSchema = z.object({
taskId: z.string().min(1, 'Task ID is required')
});
export function createTaskTools(taskManager: TaskManager) {
return {
create_task: {

}
]
};
}
}
}
};
}
Step 4: Create the Main Server
Create src/index.ts
:
#!/usr/bin/env node
import { Server } from '@modelcontextprotocol/sdk/server/index.js';
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';
import {
CallToolRequestSchema,
ListToolsRequestSchema,
ListResourcesRequestSchema,
ReadResourceRequestSchema
} from '@modelcontextprotocol/sdk/types.js';
import { TaskManager } from './task-manager';
import { createTaskTools } from './tools/task-tools';
// Initialize task manager
const taskManager = new TaskManager();
// Create MCP server
const server = new Server(
{
name: 'task-manager-server',
version: '1.0.0'
},
{
capabilities: {
tools: {},
resources: {}
}
}
);
// Get tool definitions
const tools = createTaskTools(taskManager);
const toolList = Object.values(tools);
// Handle tool listing
server.setRequestHandler(ListToolsRequestSchema, async () => {
return {
tools: toolList.map(tool => ({
name: tool.name,
description: tool.description,
inputSchema: tool.inputSchema
}))
};
});
// Handle tool calls
server.setRequestHandler(CallToolRequestSchema, async (request) => {
const { name, arguments: args } = request.params;
const tool = tools[name as keyof typeof tools];
if (!tool) {
throw new Error(`Unknown tool: ${name}`);
}
return await tool.handler(args);
});
// Handle resource listing
server.setRequestHandler(ListResourcesRequestSchema, async () => {
return {
resources: [
{
uri: 'tasks://summary',
name: 'Task Summary',
description: 'Overview of all tasks and statistics'
}
]
};
});
// Handle resource reading
server.setRequestHandler(ReadResourceRequestSchema, async (request) => {
const { uri } = request.params;
if (uri === 'tasks://summary') {
const stats = taskManager.getTaskStats();
const recentTasks = taskManager.getTasks().slice(0, 5);
const summary = {
statistics: stats,
recentTasks: recentTasks.map(task => ({
id: task.id,
title: task.title,
status: task.status,
priority: task.priority,
createdAt: task.createdAt.toISOString(),
dueDate: task.dueDate?.toISOString()
}))
};
return {
contents: [
{
uri,
mimeType: 'application/json',
text: JSON.stringify(summary, null, 2)
}
]
};
}
throw new Error(`Resource not found: ${uri}`);
});
// Start the server
async function main() {
const transport = new StdioServerTransport();
await server.connect(transport);
console.error('Task Manager MCP Server running on stdio');
}
// Handle graceful shutdown
process.on('SIGINT', async () => {
console.error('Shutting down...');
process.exit(0);
});
process.on('SIGTERM', async () => {
console.error('Shutting down...');
process.exit(0);
});
main().catch((error) => {
console.error('Fatal error:', error);
process.exit(1);
});
6. Testing Your MCP Server
Testing is where 90% of developers skip steps and end up with broken servers in production.
Step 1: Build Your Server
npm run build
If you see any TypeScript errors, fix them before proceeding.
Step 2: Test with Development Mode
npm run dev
This should start your server. You’ll see:
Task Manager MCP Server running on stdio
Step 3: Test with MCP Inspector
The MCP Inspector is a web-based tool for testing MCP servers:
# Install the inspector globally
npm install -g @modelcontextprotocol/inspector
# Test your server
npx @modelcontextprotocol/inspector node dist/index.js
This opens a web interface where you can:
- View all available tools
- Test tool execution with different parameters
- Debug any issues
- View resource content
Step 4: Manual Testing Scenarios
Test these scenarios to ensure everything works:
- Create a task:
- Tool:
create_task
- Parameters:
{"title": "Test task", "description": "This is a test", "priority": "high"}
- Tool:
- List tasks:
- Tool:
list_tasks
- Parameters:
{}
- Tool:
- Update task status:
- Tool:
update_task_status
- Parameters:
{"taskId": "task-1", "status": "completed"}
- Tool:
- Get statistics:
- Tool:
get_task_stats
- Parameters:
{}
- Tool:
7. Connecting to AI Clients
Now for the exciting part—watching AI agents actually use your tools.
Claude Desktop Setup
Go to File > Settings > Developer Tab

Step 1: Locate Configuration File
Windows:

%APPDATA%\Claude\claude_desktop_config.json
Mac:
~/Library/Application Support/Claude/claude_desktop_config.json
Linux:
~/.config/Claude/claude_desktop_config.json
Step 2: Add Your Server
Create or edit the configuration file:
{
"mcpServers": {
"task-manager": {
"command": "node",
"args": ["/absolute/path/to/your/project/dist/index.js"],
"env": {}
}
}
}
Step 3: Restart Claude Desktop
Close and reopen Claude Desktop. You should see your tools available.

VS Code with MCP Extension
Step 1: Install MCP Extension
Search for “Model Context Protocol” in the VS Code extensions marketplace.
Step 2: Configure in Workspace Settings
Add to .vscode/settings.json
:
{
"mcp.servers": {
"task-manager": {
"command": "node",
"args": ["./dist/index.js"],
"cwd": "${workspaceFolder}"
}
}
}
Cursor IDE Setup

Step 1: Open MCP Settings
Go to Settings → Extensions → MCP
Step 2: Add Server Configuration
{
"task-manager": {
"command": "node",
"args": ["./dist/index.js"]
}
}
8. What to Write in Claude to Test Your MCP Server
Once Claude Desktop restarts, try these commands:
1. Check if MCP Server is Connected

Just ask:
Do you have access to any task management tools?
You should see Claude mention the available tools.
2. Create Your First Task

Create a task titled "Learn MCP Development" with description "Build my first MCP server with TypeScript" and set priority to high

3. List All Tasks
Show me all my current tasks

4. Update a Task Status
Update task-1 to completed status

5. Get Task Statistics
Give me statistics about all my tasks

6. Create Tasks with Due Dates
Create a task "Deploy to production" with description "Deploy the MCP server to production environment" with high priority and due date 2025-01-15

7. Filter Tasks
Show me only high priority tasks

Show me only completed tasks

9. Where is Your Data Stored?
Current Setup (In-Memory Storage)
With your current setup, data is stored in memory only. This means:
- During the session: All tasks persist while the MCP server is running
- After restart: All data is lost when you restart Claude Desktop or your computer
- Location: RAM memory only
Sample Data Location
Your server automatically creates these sample tasks when it starts:
- Task ID:
task-1
- Title: “Set up CI/CD pipeline”
- Description: “Configure GitHub Actions for automated testing and deployment”
- Priority: High
- Tags: [“devops”, “automation”]
- Task ID:
task-2
- Title: “Write API documentation”
- Description: “Document all REST endpoints with examples”
- Priority: Medium
- Tags: [“docs”, “api”]
How to View Raw Data
You can also ask Claude:
Show me the task summary resource
This will display the raw JSON data including statistics and recent tasks.
10. Troubleshooting Common Issues
Here are the exact solutions to problems 95% of developers encounter.
“Command not found” Errors
Problem: node: command not found
Solution:
# Check if Node.js is in PATH
echo $PATH
# Add Node.js to PATH (adjust path as needed)
# Windows (PowerShell)
$env:PATH += ";C:\Program Files\nodejs"
# Mac/Linux (bash)
export PATH="$PATH:/usr/local/bin"
TypeScript Compilation Errors
Problem: Cannot find module '@modelcontextprotocol/sdk'
Solution:
# Reinstall dependencies
rm -rf node_modules package-lock.json
npm install
# Verify TypeScript can find modules
npx tsc --showConfig
Port Already in Use
Problem: Server won’t start due to port conflicts
Solution: MCP servers use stdio, not HTTP ports. If you see port errors, you’re likely running a different type of server.
Permission Denied
Problem: Cannot execute the server
Solution:
# Make the file executable (Mac/Linux)
chmod +x dist/index.js
# Windows: Run PowerShell as Administrator
MCP Client Can’t Connect
Problem: Claude Desktop or VS Code can’t connect to your server
Solution:
- Verify the file path is absolute
- Check that the built file exists:
ls dist/index.js
- Test manually:
node dist/index.js
- Check the client logs for specific errors
Debugging Tips
Enable Debug Logging:
Add to your src/index.ts
:
// Add at the top
const DEBUG = process.env.DEBUG === 'true';
// Add logging function
function debug(message: string, data?: any) {
if (DEBUG) {
console.error(`[DEBUG] ${message}`, data ? JSON.stringify(data, null, 2) : '');
}
}
// Use throughout your code
debug('Tool called', { name, args });
Run with debugging:
DEBUG=true node dist/index.js
Final Results
Building your first MCP server with TypeScript sets you up for unlimited automation possibilities.
What you’ve accomplished:
- Built a production-ready task management MCP server
- Learned proper TypeScript development workflows

The MCP ecosystem is exploding. With OpenAI, Google DeepMind, and Microsoft all adopting the protocol, the servers you build today will work with tomorrow’s AI breakthroughs.
Conclusion
TypeScript + MCP is the winning combination for building AI integrations in 2025.
You now have the complete foundation to build MCP servers that AI agents can actually use productively. The patterns you’ve learned scale from simple utilities to enterprise-grade automation platforms.
The most successful developers aren’t waiting for the “perfect” moment to start building. They’re shipping MCP servers every week, learning from real usage, and iterating quickly.
Your competitive advantage comes from building tools that AI agents love to use. And with this guide, you have everything you need to start building today.
Remember: The AI revolution isn’t coming—it’s here. The teams building the best MCP servers will have the biggest competitive advantages in the months ahead.
Over to You
What’s the first MCP server you’re going to build? Are you planning to extend this task manager, or do you have a completely different automation challenge in mind?
