Stateless MCP was already possible before this and made sense for whole classes of use cases where it helps to have a remote fleet of servers.

MCP is going to be a foundational piece of enterprise agent infra.
MCP was much more important when agents weren’t able to accurately make tool calls.
Nowadays, these agents are more capable and I think you can replace MCP (which is a pain on macOS), with simple CLI tools and expose them to agents via system prompt, skills, or other API documentation.
How well does that work in enterprise setups?
Well assuming a browser is able to access whatever enterprise thing, the LLM can emulate being one using apps like curl.
why is MCP a pain in Macos?
