The Model Context Protocol (MCP) is explained in detail, focusing on its internal workings for developers. The article breaks down how MCP servers are launched, often using Node.js and tools like `npx`, and highlights a common issue on Windows where servers fail to start due to shell differences. It details two primary transport mechanisms: STDIO for local communication and Server-Sent Events (SSE) for remote connections, both utilizing JSON-RPC 2.0 for message formatting. The process involves a six-step loop where the client initializes servers, assembles a prompt with a tool catalog for the LLM, and the model then decides on the appropriate tool call. AI
