MCP (Model Context Protocol)[1] is all the rage now. Introduced by Anthropic about four months ago, it has already been accepted as an open standard and has seen widespread adoption, including by major AI companies and prominent AI tool makers. There is even a directory[2] listing over 13,000 MCP implementations. Technically, it is a very simple API spec that facilitates RPC-like (Remote procedure call) communication between an AI and an external system. It enables any external system to advertise its capabilities—returning information or performing various actions—allowing AI systems to dynamically and “automagically” use those capabilities via API calls.
