Earlier quoted context omitted.

In my opinion sites that want agent access should expose server-side MCP, server owns the tools, no browser middleman. Already works today. Sites that don’t want it will keep blocking. WebMCP doesn’t change that. Your point about selenium is absolutely right. WebMCP is an unnecessary standard. Same developer effort as server-side MCP but routed through the browser, creating a copy that drifts from the actual UI. For…

So... an API? Most sites don't want to expose APIs or care enough about setup and maintenance of said API.

Can someone explain what the hell is going on here? Do websites want to prevent automated tooling, as indicated by everyone putting everything behind Cloudfare and CAPTCHAs since forever, or do websites want you to be able to automate things? Because I don't see how you can have both. If I'm using Selenium it's a problem, but if I'm using Claude it's fine??

i’m seeing this at my corporate software job now. that service that you used to have security and product approval for to even read their Swagger doc has an MCP server you can install with 2 clicks.

Well I have had the problem of "I want to find the cheapest flight that leaves during this range of dates, and returns during this range of dates, but isn't early in the morning or late at night, and includes additional fees for the luggage I need in the price comparison" and current search tools can't do that very well. I'm not very optimistic WebMCP would solve that though.
