Kudos again to the @prefect.io crew on doing documentation right for the AI era. I love everything about this -- mcp server, llms.txt and copy as markdown shortcut behavior

This is the most compelling argument I've seen thus far for MCP.
In a recent post, @chris.blue argues that MCP is an unnecessary and temporary kludge on the decline and facing an uncertain future.
IMO it standardizes how agents have stateful, identity-aware conversations.

As an open-source maintainer, one of the hardest things is saying "no" to well-designed features that are simply not a good fit.
With LLMs able to generate volumes of code without context, the maintainer's role as a thoughtful curator has never been more important.

I can't emphasize this👇 too much. Our job is not to build the most sparkly "innovative" pie-in-the-sky "unicorn" idea. Maybe one in 10,000 of those take off, and I'm being conservative. Instead, address the pain.
