Earlier quoted context omitted.

you mean this one? https://github.com/vercel-labs/agent-browser

It is 2 months old! My excuse for not keeping up is that I'm in so deep that Claude Code can predict the stock market. I'll still publish mine and see if has any value but agent browser looks very complete. Thank you for sharing!

I use Playwright to intercept all requests and responses and have Claude Code navigate to a website like YouTube and click and interact with all the elements and inputs while recording all the requests and responses associated with each interaction. Then it creates a detailed strongly typed API to interact with any website using the underlying API. Yes, I know it likely breaks everybody's terms of service but at the…

Id like to see this published as well thx!

I assume you're not logged into those sites, in order to avoid bans and the risk of hitting the wrong button like, say, "Delete Account".

I asked Claude to use this with the new scheduled tasks /loop skill to update my Oscar picks site every five minutes during tonight’s awards show. It simply visited the Oscars' realtime feed via Chrome DevTools, and updated my picks and pushed to gh pages. It even handled the tie correctly.

I know I could just use claude --chrome, but I’m used to this excellent MCP server.

I love how HN is loving this idea when it's the exact same thing Anthropic and OpenAi (and every other llm maker) did. It's God's gift to them when it lets them bypass ads and dl copyrighted material. But it's Satan's curse on humanity when the Zuck does it to train his llm and dl copyrighted material.

I would love to pay for content. I'm _paying_ for YouTube Premium.

But heck. Do I hate the YouTube interface, it degraded far past usability.

Very cool idea and site! I wish claude and others could parse video streams then you could even create your own feed.

It turns any authenticated browser session into a fully typed REST API proxy — exposing discovered endpoints as local Hono routes that relay requests through the browser, so cookies and auth are automatic.

The point is that it creates an API proxy in code that a Typescript server calls directly. The AI runs for about 10 minutes with codegen. The rest of the time it is just API calls to a service. Remove the endpoint for "Delete Account" and that API endpoint never gets called.

This 100% breaks everyone's terms of service. I would not recommend nor encourage using.

i wish more people knew or cared about web standards vs proprietary protocols. the webdriver bidi protocol took the good parts of cdp and made it a w3c standard, but no one knows about it. some of the people who do know about it, find one thing they don't like and give up. let's not keep giving megacorporations outsized influence and control over the web and the tools we use with it. let's celebrate standards and make them awesome.
