The MCP protocol is undergoing a significant revision, moving away from its session-based model to a server-rendered UI approach. This change aims to address issues like stalled tool calls experienced when MCP is used behind a load balancer, which were previously attributed to the protocol's youth. The updated spec, set to finalize on July 28, 2026, removes session IDs and enhances transport, error handling, and authorization. AI
