MCP: The Simple Protocol to Make AI Actually Useful
"Let's be honest. AI assistants are smart, but they're mostly stuck inside a chat window. They can write an email, but they can't send it. They can plan a trip, but they can't book it. To do real things, they need to connect to other apps and services - what developers call "tools." And right now, that connection is a mess."
"You had a different cable for your keyboard, your mouse, your printer... it was a tangled nightmare. Then USB came along and created one standard plug that just worked for everything. MCP aims to be the USB for AI. It's a proposed set of rules( by Anthropic, the company behind Claude) - a standard language - that lets any AI agent talk to any tool without needing a custom-built connector. It's a simple, universal agreement on how to ask for things and get a response."
AI assistants can perform tasks in chat but lack direct integrations with external apps and services, requiring developers to build custom connectors for each tool. The Model Context Protocol (MCP) proposes a standard, universal interface that lets AI agents discover and call tools without bespoke glue code. An MCP server handles a handshake, shares a menu of available tools and required parameters, and accepts requests from agents to invoke those tools. MCP reduces integration complexity, promotes interoperability across APIs and services, and enables agents to perform real-world actions like booking flights or adding calendar events more reliably.
