The Model Context Protocol, Explained for Builders
MCP is becoming the USB-C of AI tooling. Here's what it is, why it matters, and how to build your first server.
Every AI app was reinventing the same glue code to connect models to tools and data. The Model Context Protocol standardizes that boundary, so a tool you write once can be used by any MCP-aware client. In this guide I demystify the protocol—resources, tools, and prompts—and build a small MCP server that exposes a Postgres database to an assistant. I also cover the security model, why you should think hard about what you expose, and how MCP changes the way I architect AI features in full-stack apps.
