MCP (Model Context Protocol)
Definition
A shared standard that lets AI tools connect to outside services, like your calendar, your files, or a company database, in a consistent way. Before it, every connection between an AI and another tool had to be custom-built. MCP is closer to a universal adapter: build once to the standard, and many AI tools can use it. It was introduced by Anthropic and has been taken up more widely since.
Why It Matters
It's part of how AI is moving from a clever chat box to something that can actually do things with your other tools. Expect to hear the term more as that shift continues.
What does that look like in practice?
With MCP set up, you can ask one AI tool 'what's on my calendar Friday?' and it reads your actual calendar to answer.
What people actually mean when they say this
When someone says an AI 'connects to your tools,' MCP is often how: a shared standard that saves building every connection by hand.
