MCP is a shared plug-and-socket standard for connecting AI to the outside world. Instead of every company inventing its own way to hook a model up to files, tools, and services, MCP gives them one common approach. It is a bit like USB for AI: build a connector once, and many different AI apps can use it.
For example, Thanks to MCP, an assistant can connect to your calendar, your notes app, and your files through the same standard.
