What is MCP?
MCP (Model Context Protocol) is a standard way to connect AI models to data sources and tools. It allows AI to access information and capabilities beyond what they were originally trained on.
MCP works like a universal connector for AI systems. Just as standard ports let different devices work together, MCP lets different AI models connect to the same tools and data sources. This means developers can build a tool once and have it work with any AI model that supports MCP. It's like the USB-C port of AI applications.
AI models are good at generating content and reasoning, but they're limited by their training data. MCP solves this problem by giving them access to external resources when they need them.
How MCP Works
MCP uses a client-server design where applications can connect to multiple resources. The system has three main parts:
The Client Side: Making Requests
MCP Clients/Hosts are where requests begin. These include:
- AI models like Claude or GPT that need external tools
- Applications like Claude Desktop or code editors
- Any system that connects an AI model to external resources
The client sends requests through MCP to access tools or information—similar to how your web browser requests a webpage.
The Communication Layer: The Standard Protocol
The Protocol itself is the core of MCP. This standard:
- Defines the format for requests and responses
- Makes different models and tools compatible
- Handles security, errors, and data formatting
This protocol ensures all parts of the system can work together regardless of which AI model or tool is being used.
The Server Side: Providing Resources
MCP Servers connect to the resources AI models need. These lightweight programs:
- Make specific capabilities available through the standard protocol
- Provide access to tools and data
- Connect to databases for information
- Work with services like YouTube, weather data, or stock prices
- Access files for reading and writing
- Perform specialized tasks
Servers receive requests, perform the needed actions, and send results back to the AI model.
This design creates a system where AI models can access the digital world when needed. Let's look at why this matters in practice.
Why MCP Matters
Without MCP, AI models can only use what they learned during training. They can't:
- Get current information from the internet
- Query databases for specific answers
- Use specialized services like video processing
- Save information to files
- Access external tools that extend their abilities
MCP bridges this gap by giving models access to tools beyond themselves. This turns AI from isolated systems into connected applications that can solve real problems.
MCP offers three key benefits:
- Ready-to-use integrations your AI can connect to immediately
- The ability to switch between different AI providers without rewriting your connections
- Security features that keep your sensitive data protected
MCP in Action
Here's a simple example from the video:
- An AI model receives a YouTube URL
- Through MCP, it connects to a service that gets YouTube transcripts
- The service returns the transcript to the model
- The model summarizes the content
- Using another MCP service, it saves the summary to a file
Without MCP, each step would require custom code and integration. With MCP, it's a standard process that works across different AI systems.

MCP supports multiple programming languages including Python, TypeScript, Java, and others. Whether you're creating new services or using existing ones, there's a path for you.
Core Capabilities
MCP provides several key features:
- Resources: Share data and content with AI models
- Prompts: Create reusable templates for consistent AI interactions
- Tools: Let AI models perform actions through your services
- Sampling: Allow your services to request information from AI models
- Transports: Connect clients and servers efficiently
The Future of AI Integration
MCP represents an important step forward in AI development. It enables:
- AI applications that can interact with real-world systems
- Easier development across different AI models
- Standard ways to extend AI capabilities
- A growing collection of specialized tools any AI can use
As AI continues to develop, connecting models to external tools and data will become increasingly important. MCP provides the foundation for this integration.
Wrapping Up
MCP changes how we think about AI capabilities by connecting models to specialized tools and resources.
Understanding MCP helps you see how AI can work with the digital world around it. It's about making AI more useful by giving it access to the tools and information it needs.
With our platform, you can build AI applications with expanded capabilities. I look forward to seeing what you'll create.
