The Model Context Protocol (MCP) project has released a candidate for its 2026-07-28 specification, marking a significant infrastructure upgrade for remote coding agent servers. This update removes protocol-level sessions, allowing any server instance to handle requests, which simplifies scaling with round-robin load balancers. It also introduces Multi Round-Trip Requests to manage user interactions mid-process without sticky sessions and adds routing-friendly headers for better gateway integration and observability. AI
IMPACT Simplifies scaling and improves reliability for AI agent infrastructure, enabling more robust production deployments.
RANK_REASON This is an infrastructure update for a protocol used by AI agents, not a new AI model release or core research.
