Based on a tutorial by Việt Nguyễn AI
If you’ve been struggling with the limitations of AI models like ChatGPT, Claude, or Gemini – wondering why they can’t access your local files, browse the web, or connect to your company’s databases – you’re not alone.
This comprehensive guide breaks down Việt Nguyễn’s excellent tutorial on Model Context Protocol (MCP), showing you exactly how to supercharge your AI tools without any programming knowledge required.

Understanding Current AI Model Limitations
Before diving into MCP, Việt Nguyễn explains the fundamental challenges that plague today’s large language models. These aren’t just minor inconveniences – they’re significant barriers that prevent AI from reaching its full potential.
Key Limitations:
- Knowledge Cutoff Dates: ChatGPT O1 Mini’s knowledge stops at October 2023, Claude 3.5’s at November 2024
- No Direct Web Access: Most models can’t browse URLs or access web pages directly
- Local File Restrictions: Cannot access files stored on your computer or cloud storage
- Enterprise System Isolation: No connection to company databases, CRMs, or internal tools
My Take:
These limitations make perfect sense from a security perspective, but they’ve created a massive gap between AI’s potential and its practical utility. It’s like having a brilliant research assistant who’s locked in a room with only old textbooks.
What is MCP and Why We Need It
Model Context Protocol (MCP) is Anthropic’s solution to the fragmentation problem. Think of it as the “USB-C for AI” – a universal standard that lets any AI model connect to any external tool or data source.
The Problem MCP Solves:
- Each AI model has its own integration standards
- Every external service has different connection requirements
- Developers face hundreds of different integration combinations
- Building integrations becomes a nightmare for both developers and users
As Việt Nguyễn brilliantly explains using a laptop analogy: instead of every laptop manufacturer creating their own unique port, and every peripheral requiring its own special cable, MCP standardizes everything into one universal connection type.
My Take:
This standardization is huge. It means developers only need to build one integration instead of dozens, and users can mix and match AI models with tools without worrying about compatibility.
MCP Architecture: How It All Works Together
Understanding MCP’s architecture helps you grasp why it’s so powerful. The tutorial breaks it down into five essential components:
MCP Components:
- MCP Host: The AI model (Claude, ChatGPT) or development tool (VS Code, PyCharm)
- MCP Server: Specialized servers for each external service (GitHub, Google Drive, Notion)
- MCP Client: Maintains 1:1 connections between hosts and servers
- Local Resources: Files, databases, and tools on your machine
- Remote Resources: Internet-accessible services and APIs
The beauty of this architecture is its simplicity. Once you connect an MCP server to your AI model, you immediately gain access to all the capabilities that server provides.
Setting Up MCP with Claude Desktop
Here’s where the tutorial gets practical. Việt Nguyễn walks through the complete setup process, making it accessible even for non-programmers.
Prerequisites:
- Download and install Claude Desktop application
- Install Node.js (required for running MCP servers)
- Access to the MCP servers repository on GitHub
Configuration Steps:
- Open Claude Desktop settings (three-line menu → File → Settings)
- Navigate to Developer tab and click “Edit Config”
- Modify the config file to include your chosen MCP servers
- Restart Claude Desktop to activate the connections
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["@modelcontextprotocol/server-filesystem", "C:UsersYourUsernameDesktop", "C:UsersYourUsernameDownloads"]
}
}
}
My Take:
The configuration process is surprisingly straightforward. The hardest part is remembering to restart Claude Desktop after making changes – a step that’s easy to forget but absolutely crucial.
File System MCP Server Demo
The first practical demonstration shows the transformation from limitation to capability. Before MCP integration, Claude Desktop couldn’t access local files. After? It becomes a powerful file management assistant.
File System Server Capabilities:
- Read and write files
- Create and delete directories
- Move and rename files/folders
- Search for files by name or content
- Extract file metadata and information
The demo shows Claude Desktop successfully listing and describing desktop contents – something that would have been impossible before the MCP integration. The AI can now see folder structures, file types, and even provide summaries of directory contents.
My Take:
This capability alone transforms Claude from a text-based assistant into a genuine productivity tool. Being able to organize, search, and manage files through natural language commands is genuinely game-changing.
Browser Automation MCP Server
The second demonstration tackles web access limitations. By integrating the Puppeteer MCP server, Claude Desktop gains the ability to browse the web, interact with pages, and extract content from any URL.
Browser Automation Features:
- Navigate to any URL
- Take screenshots of web pages
- Click elements and fill forms
- Extract text content from pages
- Interact with dynamic web applications
The tutorial demonstrates this by asking Claude to summarize a YouTube video – a task that was previously impossible. With the browser automation server connected, Claude can access the video page, extract relevant information, and provide a comprehensive summary.
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["@modelcontextprotocol/server-filesystem", "C:UsersYourUsernameDesktop"]
},
"puppeteer": {
"command": "npx",
"args": ["@modelcontextprotocol/server-puppeteer"]
}
}
}
My Take:
This web browsing capability essentially gives Claude “eyes” for the internet. You can now ask it to research topics, compare products, or analyze websites in real-time – capabilities that rival and often exceed traditional web scraping tools.
Conclusion and Next Steps
Việt Nguyễn concludes by highlighting the vast ecosystem of available MCP servers. The demonstrations with file system and browser automation represent just a fraction of what’s possible.
Available MCP Servers Include:
- GitHub and GitLab integration
- Google Drive and cloud storage
- Slack and communication tools
- Database connectors (SQL, MongoDB)
- API integration tools
- Custom business system connectors
The tutorial promises a follow-up video on building custom MCP servers, opening the door for truly personalized AI integrations tailored to specific business needs.
My Take:
MCP represents a fundamental shift in how we think about AI integration. Instead of waiting for AI companies to build every possible integration, we now have a standardized way to connect AI to any tool or data source. This democratizes AI customization in a way we’ve never seen before.
