MCP (Model Context Protocol)
An open standard for connecting AI models to external tools and data sources in a consistent way, so one tool works across many apps.
It is becoming the universal plug for agents, the way a USB port standardized devices.
Frequently asked questions
What is MCP in simple terms?
MCP, the Model Context Protocol, is an open standard for connecting AI models to outside tools and data in a consistent way. The payoff is that one tool built for MCP can work across many different AI apps.
Why do people compare MCP to a USB port?
Because just as USB gave every device one standard plug, MCP aims to be the universal plug between agents and tools, so builders do not have to create a custom connection for every combination. It is becoming a common standard for hooking agents up to data and services.
Do I need to understand MCP to use AI?
Not to use everyday AI tools, no; MCP is mostly a behind-the-scenes plumbing standard for connecting agents to tools. It is worth knowing the name because it is shaping how AI systems get wired together.
