How much of this can or can't be done by a Extension or Bookmarklet running JS in a page? What is your biggest dream from standardizing this?

If there's a standard instead of needing to download the Jira mcp server, you just visit their website and all the tools are described and usable from there.
Or put differently, as a company / group / individual, instead of needing to build and distribute an mcp server and public API, you can just support WebMCP.
Another alternative is LLMs / agents operating playwright or the equivalent which will likely be less reliable and consume more tokens. (By a fair margin)
it seems like a cleaner approach to declare a handful of tools that users can approve/ask for granularily, than just say "my website can run any wacky script, here is some bookmarklet, nerds" or the very generic permission model of browser extensions
Couldn't that be solved with a simple bookmarklet permission model? The script would request the same pop-up features as a website?
It's more providing permission granularity on the action level rather than the sandbox level. Your script might not be able to make external api calls, but there is no way to gate the ability to take destructive action within the webpage.
With something like WebMCP you get elicitation and the ability to disable tools from the client.
