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??

They will wish that you use an official API, follow the funnel they settled for you, and make purchases no matter how

Majority of sites don't even expose accessibility functionalities, and for WebMCP you have to expose and maintain internal APIs per page. This opens the site up to abuse/scraping/etc.

Thats why I dont see this standard going to takeoff.

Google put it out there to see uptake. Its really fun to talk about but will be forgotten by end of year is my hot take.

Rather what I think will be the future is that each website will have its own web agent to conversationally get tasks done on the site without you having to figure out how the site works. This is the thesis for Rover (rover.rtrvr.ai), our embeddable web agent with which any site can add a web agent that can type/click/fill by just adding a script tag.

Not fine if you use Claude. But it's fine if you are Google Flights and the user uses Gemini. The paid version of course.

Sadly I do see this slop taking off purely because something something AI, investors, shareholders, hype. I mean even the Chrome devtools now push AI in my face at least once a week, so the slop has saturated all the layers.

They don't give a fuck about accessibility unless it results in fines. Otherwise it's totally invisible to them. AI on the other hand is everywhere at the moment.

Earlier quoted context omitted.

I want my local dm shop to offer me their product info as copyable markdown, ingredient list, and other health related information. This could be a way to automate it.

Since you didn't say what a "dm shop" is, I'll assume you mean "dungeon master shop" where you buy Dungeons and Dragons-y stuff. Or maybe it's a "direct marketing shop", where you bring flyers to be delivered into people's mail? Yeah, that must be it.

Given that it's about food or medicine somehow, because of the mention of ingredients lists and health-related information, it's probably https://en.wikipedia.org/wiki/Dm-drogerie_markt (usually abbreviated "dm").

(I didn't know about that either before now.)

I suspect people will get pretty riled up in the comments. This is fine folks. More people will make their stuff machine-accessible and that's a good thing even if MCP won't last or if it's like VHS -- yes Betamax was better, but VHS pushed home video.

>Users could more easily get the exact flights they want Can we stop pretending this is an issue anyone has ever had.

He probably means the large German drug store chain called DM.

They wanna let you use the service the way they want.

An e-commerce? Wanna automate buying your stuff - probably something they wanna allow under controlled forms

Wanna scrape the site to compare prices? Maybe less so.

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.

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.
