Last month, I was building an AI assistant for an e-commerce system. The idea was simple: let users ask natural-language questions about orders and products through a chat interface. I used the Model Context Protocol (MCP) to connect my AI agent to internal tools -- inventory lookup, order tracking, customer history.
It worked. Until the WebSocket connection dropped at 2 AM, the server ran out of file descriptors under load, and I realized my stateful SSE transport could not scale across multiple instances behind a load balancer.
If that sounds familiar, the news from July 28, 2026 is exactly what you have been waiting for. MCP just went stateless.
I am a Software Engineer from Bangladesh. I work with Spring Boot daily and run my own AI agent infrastructure on the side. Here is what the MCP 2026-07-28 spec means for Java developers, and how to build a production-ready stateless MCP server with Spring AI 2.0.
What MCP Is (And Why the Change Matters)
