Every request will now be self-contained, allowing any server to process it independently. New features include Multi Round-Trip Requests (MRTR), routable transport headers for API gateways, an updated OAuth 2.1/OpenID Connect authorization framework, and deterministic caching to improve LLM prompt-cache hit rates. Several legacy features are being deprecated — most notably Sampling, which changes how servers interact with foundation models and requires rebuilding trust boundaries, network architecture, and billing flows. Updated SDKs for Python, TypeScript, Go, and C# support both old and new protocol versions for backward compatibility. Teams have a one-year transition window before deprecated features are removed. ## Full article daily.dev links to this article rather than hosting it.
