MCP
MCP is a standard way to connect an AI agent to an outside service, so it can read from that service or act in it.
Also called: Model Context Protocol, connector
MCP stands for Model Context Protocol. It plugs your agent into a service, your store, your calendar, a set of files, so it can look things up there instead of guessing. Think of it as a plug shape: the service builds one socket, and any agent with the matching plug can use it.
You will meet it the first time you want your agent to answer a question about real data, not about the files in front of it.
The thing people get wrong is hearing MCP and thinking intelligence. It is plumbing. A connection carries exactly the permission you handed it, and one that can change an order can change an order.
