The Model Context Protocol (MCP) has released its largest update to date, with the July 28, 2026 specification focusing on transforming the protocol from a research prototype into robust infrastructure. Key changes include making the core protocol stateless by removing session pinning and handshake requirements, allowing any server instance to handle requests. This revision also rebuilds server-to-client communication to function without persistent connections, ensuring that all requests are self-contained and traceable to a client-initiated action. AI
