MCP Protocol Status and Stateless Specification Update
August 31, 2026
The Model Context Protocol is moving toward a stateless specification (version 2026-07-28) that eliminates initialize handshakes and session IDs. Support for elicitation via JSON-schema forms and URL dialogs is available in SDK 2.x, though some providers like Bedrock and Vertex remain on v1.
