What is MCP?
The Model Context Protocol: one open standard that lets any AI app plug into your systems.
Every AI app needs to reach your other software. Your database. Your files. Your repo. And every one of those connections used to be custom glue code.
What it is
MCP, the Model Context Protocol, is an open standard that fixes that. Think of it like a USB-C port for AI. One plug shape. Any app.
How it works
There are two sides. The client lives inside the AI app. Like Claude Code. The server wraps your software, and lists what it offers: tools the AI can run, and data it can read. They talk in JSON, on your machine or over the web.
Why it matters
So you build one server, and every app that speaks MCP can use it. Claude. ChatGPT. VS Code. Cursor.
