Model Context Protocol (MCP) transitions to stateless design

By PulseAugur Editorial · [3 sources] ·

The Model Context Protocol (MCP) has transitioned to a stateless design, as detailed in its July 28, 2026 specification revision. This change removes protocol-level sessions, making MCP servers easier to operate and scale. Instead of relying on session IDs, each request now carries all necessary information, including protocol version and client capabilities. While protocol sessions are gone, application state can still be managed through explicit "handles" returned by tools, allowing clients to refer to specific resources like browser instances across multiple requests.
