Background & analysis
The MCP protocol introduced a stateless variant this year, with changes delivered in the 2026-07-28 specification. This event is currently covered by a single report, published on 2026-11-06 15:00 by the AI section of DEV Community. The report argues that the shift has made the 'supports MCP' label ambiguous: the claim used to mean one specific thing, but the report says there are now effectively two MCPs, and most vendors are not saying which one they mean. As a result, the report advises anyone building or buying agent-adjacent products to confirm with the counterparty which of the two implementations is supported, and to plan for migration. It adds that no one has scheduled this migration. No further developments have been reported since.
