[Model Context Protocol (MCP) Undergoes Major Upgrade, Fully Transitioning to Stateless Architecture] According to VentureBeat, the Model Context Protocol (MCP) is undergoing its largest update since its launch in November 2024, managed by the Agentic AI Foundation (AAIF) under the Linux Foundation. This update completes the transition to a fully stateless architecture, enabling MCP servers to be deployed behind standard load balancers without relying on 'sticky routing' or shared session states, thereby simplifying large-scale cloud-native and Kubernetes deployments. In terms of security, the new version of MCP enforces validation of the issuer (iss) parameter for OAuth and OpenID Connect to prevent mix-up attacks. It also introduces enterprise-hosted authorization extensions to support unified identity governance for enterprises.
