🔥Model Context Protocol (MCP) Explained | Architecture, Transport Layer & Spring AI Implementation

Model Context Protocol (MCP) is changing how LLMs interact with tools, files, and external systems — and in this video, you’ll understand MCP from absolute basics to real implementation. This 1-hour deep-dive explains: What MCP is and why it exists MCP architecture explained visually and logically How MCP transport layer works (communication mechanism) MCP Host, Client, and Server responsibilities How LLMs interact with MCP internally Real MCP FileSystem implementation using Spring Boot and Spring AI ⏱️ Video Chapters 00:00 – 00:51 Introduction to MCP & why it matters in AI 00:51 – 03:05 Why AI apps can’t access external systems 03:05 – 05:40 Limitations of function & tool calling 05:40 – 07:36 What is MCP? Open standard explained 07:36 – 08:46 Exploring official MCP documentation 08:46 – 10:43 MCP as USB-C for AI (Best analogy) 10:43 – 12:37 What MCP enables & why developers need it 12:37 – 13:42 MCP architecture: Host, Client & Server 13:42 – 14:02 MCP layers: Data & Transport 14:02 – 14:49 Why MCP when HTTP already exists? 14:49 – 21:19 Deep dive: MCP working flow 21:19 – 22:56 MCP implementation plan (Spring Boot) 22:56 – 27:07 Finding MCP servers on GitHub 27:07 – 29:52 Use cases & next steps 29:52 – 32:29 Creating Spring Boot project 32:29 – 34:57 Adding required dependencies 34:57 – 36:31 OpenAI API configuration 36:31 – 38:15 Creating REST controller 38:15 – 39:30 ChatClient demo (without MCP) 39:30 – 41:20 Connecting to MCP server 41:20 – 43:30 Running File System MCP Server 43:30 – 46:00 Verifying MCP server & tools 46:00 – 47:45 MCP client configuration 47:45 – 50:30 Injecting MCP client in Spring Boot 50:30 – 52:00 Enabling tool calling 52:00 – 54:30 Creating files using MCP 54:30 – 56:00 How AI selects tools automatically 56:00 – 58:00 Testing MCP integration 58:00 – 01:00:00 File creation verification 01:00:00 – 01:02:00 Real-world power of MCP 01:02:00 – 01:04:00 Complete MCP flow recap 01:04:00 – 01:06:00 Final thoughts & next learning steps If you’re a Java developer, backend engineer, or exploring LLM infrastructure, this video will give you a clear mental model + practical implementation.
