New MCP spec update addresses enterprise adoption barriers

Ars Technica reports a specification update for the Model Context Protocol (MCP), the widely-adopted standard for connecting AI models to external tools and data. The update includes a policy ensuring existing features aren't removed suddenly, addressing a key concern for enterprises building on the protocol.

Why it matters: MCP has become a de facto standard for agentic tool use since Anthropic introduced it, and this stability guarantee matters because enterprises need assurance that integrations built today won't break as the spec evolves quickly. It's a sign the protocol is maturing from an experimental convention into infrastructure companies are willing to build production systems on.
