The Ultimate MCP Crash Course - Build From Scratch

Model Context Protocol (MCP) is a communication protocol that enables AI clients to interact with servers through four main components: tools (functions AI can call), resources (data access), prompts (pre-created prompts), and samplings (server requests to AI). The tutorial demonstrates building both MCP servers and clients from scratch using TypeScript and Node.js, showing how to create tools for database operations, expose resources for data access, implement prompts for AI interactions, and use samplings for server-to-client communication. Integration examples include connecting to GitHub Copilot and using an MCP inspector for testing and debugging.
