Google Cloud engineers Kurtis Van Gent and Alan Blount announced the release of a new Model Context Protocol (MCP) specification on 2026-07-28.[^1]

The new 2026-07-28 specification transitions the Model Context Protocol from a stateful session model to a stateless core to support millions of concurrent queries on cloud infrastructure.[^3] The Model Context Protocol Transports Working Group was co-founded by Google, Hugging Face, and other industry partners to decouple the protocol from stateful transport constraints.[^2]

Google DeepMind and Google Cloud AI are joining the Agent Plugins Technical Steering Committee (TSC) as Core Maintainers to build support for the specification in their own products.[^7] Google Cloud described the model routing feature as part of its broader AI gateway spectrum, which includes Apigee for API and tools management and Agent Gateway in the Gemini Enterprise Agent Platform for agent governance.[^8] Cisco supports open standards including Agent2Agent and the Model Context Protocol to allow Webex agents to work alongside third-party systems.[^4]
