I actually think webmcp is incredibly smart & good (giving users agency over what's happening on the page is a giant leap forward for users vs exposing APIs).
But this post frustrates the hell out of me. There's no code! An incredibly brief barely technical run-down of declarative vs imperative is the bulk of the "technical" content. No follow up links even!
I find this developer.chrome.com post to be broadly insulting. It has no on-ramps for developers.
