The Model Context Protocol specification release candidate (locked May 21, stable July 28, 2026) makes the protocol fully stateless — no handshakes, no session IDs, no sticky routing. Alongside that headline change, it graduates the extensions framework to first-class status, introduces MCP Apps for server-rendered UI, formalizes the Tasks extension for long-running work, adds production-grade observability headers, upgrades to full JSON Schema 2020-12, and hardens OAuth 2.0 authorization through multiple SEPs. Three features — Roots, Sampling, and Logging — are deprecated under a new lifecycle policy with a one-year sunset window.

AI coding tools are great at boilerplate, but they still hallucinate web API details, browser support, and even whether a feature exists at all. MDN's new MCP Server tackles that problem by letting MCP-compatible editors and agents pull current MDN documentation and browser compatibility data straight from the source.

When your product is an AI assistant, using AI to build it feels natural — but doing it well is harder than it sounds. The AI-Assisted Development section describes these patterns in the abstract. This post is what they look like after a year in production on a real Aliz frontend: a React + TypeScript chat-based AI assistant with theming, 18-language internationalization, MCP integrations, and multi-environment deploys. The codebase is large enough that no single prompt can reason about it coherently, which is the whole reason the team stopped reaching for a tool and started building a system — the same shape described in Multi-Agent Orchestration. Three layers of AI setup, a team of specialist agents, and a workflow called QRSPI hold it together.
