MCP Architecture | Model Context Protocol Architecture | CampusX

In this video, we dive deep into the Model Context Protocol (MCP) Architecture and break it down from first principles. We’ll cover: The core building blocks of MCP → Host, Client, and Server How they communicate and why the Client is essential Real-world examples (GitHub, Slack, Google Drive) The power of primitives: Tools, Resources, and Prompts Standard operations like tools/list, resources/read, and more The role of the Data Layer (JSON-RPC 2.0) and why it’s better than REST The Transport Layer and how messages actually move between systems By the end of this video, you’ll have a crystal-clear understanding of how MCP enables AI chatbots to seamlessly connect with external tools, scale across multiple services, and maintain safe, decoupled communication. ============================ Did you like my teaching style?
