"Every time a developer wants their AI agent to use a new tool, like a weather API or a flight booking system, they have to build a custom bridge. It's like needing a different, clunky adapter for every single device you own."
"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."
"The Handshake: An AI agent connects to an MCP server and asks, "Hey, what can you do?" The Menu: The server sends back a simple list of its available tools and what information each one needs. For example: get_current_weather(location: string) book_flight(destination: string, date: string) add_to_calendar(event_name: string, time: string)"
AI assistants can perform language tasks but lack direct access to external apps and services, so they cannot complete actions like sending emails or booking trips. Developers currently build custom adapters for each tool, creating fragmentation and engineering overhead. The Model Context Protocol (MCP) defines a standard handshake and menu system enabling an MCP server to advertise available tools and parameters. AI agents query the server, discover available functions, and invoke tool operations without bespoke glue code. MCP aims to create plug-and-play interoperability across APIs, simplifying integration for weather, booking, calendar, and similar services.
