“It's like giving your website an API of how you expect it to be used. That's what both MCP and WebMCP are. I would wager that WebMCP is a little easier to get out, because you're not building your own authenticated server.”

Coyier was summing up the state of WebMCP, a proposed browser standard that lets pages register tools AI agents can call directly. He says many developers he's asked are curious about it as a simpler way to make sites agent-friendly.

cool, though. It's like, hey, there's a command for formatting. I should call that. You kind of don't blame it in a way. We exposed that tool. So it called the tool. That's pretty cool. And the confetti is great. I'm so used to that. That's a better thing. Confetti.js.
Yeah. This is a direct canvas drawing approach that they
just did it itself. It didn't even pull in a dependency. No, that's hilarious. That's nicer than Confetti.js, I think. That looks like very colorful. Anyway, you'll have to watch the YouTube video, all you car commuters. Come on. Pretty cool. So there's the ChatGPT implementation. There's the agent browser implementation. There's Google's own web extensions that you can put into Chrome. And that's about it. That's what I mean while I started the show saying this is very cutting edge stuff. There's not that much implementation of this yet, but it's cool, you know. And I've asked around people, like, how are you feeling about this? A lot of people are like, hey, I'm WebMCP curious. You know, I'm thinking about putting into my app because it does feel like, and there's certainly a good amount of rhetoric around like websites should be better at letting agents use them. Like there's just a lot of people doing AI stuff. It's just the way it is. So if you can help them do that on your website, it's kind of like…
well, it's kind of meeting users where they're at. Like users aren't necessarily going to go to ChatGPT to ask it to, you know, like go add something to their Google Calendar. But if they're on Google Calendar and they can open up a drawer that just lets them use natural language and create all…
pretty cool. I'd love it to see. Oh, look at that. Look at that. You're making stuff happen here. This is really cool. I'd love to see if you try it. Try it in the ChatGPT app. Pretty chill way to do it. And we'll let you know. And MCP is coming as well, which is just powerful in another way. It's…
Yeah. Enjoy.
