Google describes a stateless release candidate for the Model Context Protocol
2026-08-05 · Source
Google announced that the Model Context Protocol release candidate dated July 28, 2026 removes transport-level session management from the protocol core. The post describes the resulting design as stateless and says the handshake and logical session identifier have been removed. Google states that requests can be routed across ordinary HTTP load-balanced infrastructure without preserving protocol session state. The change is presented as a way to scale MCP-based agent infrastructure using conventional web deployment patterns. Agent developers will need to account for the revised request model when implementing clients, servers, and infrastructure around the release candidate.
Why it matters: The stateless design lets MCP services operate behind standard HTTP load balancers without transport-level session affinity, reducing infrastructure constraints for agent commerce deployments.
