The Model Context Protocol (MCP): A Beginner's Guide to AI's USB-C Moment

Short summary

The Model Context Protocol (MCP) is an open standard that lets any AI app connect to any tool or data source through a unified interface, solving the N×M integration problem. It defines three roles—Host (AI app), Server (capability provider), and Client (connector)—plus tools, resources, and prompts as primitives. MCP is spreading fast because tool builders write one server and instantly work with every compatible AI app, while users get assistants that can safely access their real files and data.
