MCP Just Hit Release Candidate. Here's What Builders Actually Get.

The Model Context Protocol just reached its release candidate, with the final spec landing July 28. Three things matter for anyone building on Claude.

A stateless core

MCP servers no longer have to hold a session open. That means cheaper hosting, easier scaling, and configs that survive restarts — exactly what you want when you self-host your stack.

Tasks and MCP Apps

Long-running jobs become first-class, and servers can ship their own UI. Your "research bot" or "scraper" stops being a script and becomes a real, reusable tool.

Why it matters

With 97M+ SDK downloads a month, MCP isn't a bet anymore — it's the standard. The builders who set up their MCP stack now will be the ones not paying for ten SaaS tools next year.
