Stateless Redesign of MCP Specification Aims to Unlock Enterprise Scalability

The Model Context Protocol (MCP), an open standard for connecting AI systems to external tools and data sources, has received its biggest update since launch. The protocol core is now stateless, meaning requests no longer rely on sessions tied to a single server instance. According to lead maintainers David Soria Parra and Den Delimarsky of Anthropic, this change directly addresses key scalability barriers that have hindered enterprise adoption.
