The open-source Model Context Protocol (MCP), known as a standard for the interaction of AI systems with peripheral tools and data sources, has seen its largest update since its introduction.
The most significant change in this version is the core of the MCP protocol becoming Stateless. With this change, requests are no longer dependent on specific sessions tied to a single server instance. This key development has high potential to remove long-standing barriers in the path of AI scalability and facilitates its use across large-scale organizations.
