The “USB-C for AI” comparison gets used constantly to describe MCP. Is that the best way to think about it?
It gets the most important part right: one standard connector instead of a different custom cable for every device. Before something like MCP existed, connecting an AI agent to a new system meant custom integration work for that specific agent and that specific system, every single time.
MCP means an AI agent that already knows how to speak MCP can plug into any system that also speaks MCP, including ours, without custom glue code built just for that pairing.
Where the analogy runs out is that USB-C just moves electricity and data. MCP moves understanding, since it’s the format that lets an agent understand what’s on the other end of the wire well enough to use it correctly and safely, which is a much bigger job than a physical connector has to do.
I’d actually point to HTTP as the better analogy, both from the problem it solves and for how it works. HTTP standardized how browsers and servers talk to each other across the web. MCP does the same job for AI, it standardizes how agents discover, understand and interact with external systems and tools.
