The hope is that the changes, detailed in the protocol’s documentation, will make widespread deployment in an enterprise context much easier. MCP started as something that simply ran on a local machine, connecting models to local apps, so the new spec is a major rethink of some of its foundations. This is again in keeping with the general “let’s make this work better at enterprise scale” theme of the new specification. MCP was originally introduced by Anthropic, just shy of two years ago, and Anthropic still has significant influence over its direction. The buck technically stops with individual maintainers, not any of these companies themselves, but as noted above, some of the principal maintainers currently work at Anthropic.
