MCP Is the USB Port for AI Tools

Before USB, connecting a mouse to a computer was a lottery. PS/2 ports, serial ports, proprietary connectors from every vendor. Then USB showed up and the whole problem disappeared. One standard. Everything just worked. That is exactly what Model Context Protocol is doing for AI right now. What MCP Actually Is MCP is an open protocol, originally created by Anthropic in November 2024, that defines a standard way for AI models to connect to external tools, data sources, and systems. Built on JSON-RPC 2.0 and inspired by the Language Server Protocol that powers every modern code editor, it gives you three core primitives: Tools, Resources, and Prompts. Instead of every AI product needing a custom integration with every other tool, MCP gives you one interface that works everywhere. Think of it as the difference between writing a separate driver for every printer versus having a USB port that any printer can plug into. The numbers back this up. The MCP ecosystem has grown to over 97 million
