With that being said, it tells you that the HN algorithm is either broken, gamed or both.
That is to say, I don't think this is a consumption issue - it's a production issue.
Also, with social media becoming increasingly broken, the distribution of non-hype AI blog posts is entirely dead outside of the coin flip of getting the post to the top of Hacker News, which is less rewarding. It's a chicken-and-egg problem.
But as always in times of lots of hype, this get no attention and no-one cares.
They also look to be selling the kind of filtering/guardrails solution that I argue in my talk doesn't actually work. (Update: that's a little unfair, I had a look and a bunch of their rules are at least deterministic, like making sure DELETE isn't present in a call made to a database MCP.)
If you're looking for credible sources on MCP and prompt security that aren't my blog, I strongly recommend https://embracethered.com/blog/
