Earlier quoted context omitted.

On one hand, cool demo, on the other, this is horrifying in more ways than I can begin to describe. You're literally one prompt injection away from someone having unlimited access to all of your everything.

Of course I still watch it and have my finger on the escape key at all times :)

For now you are. All these things fall with time, of course. You will stop caring once you start feeling safe, we all do.

Also. AAarrgh, my new thing to be annoyed at is AI drivel written slop.

"No browser automation framework, no separate browser instance, no re-login."

Oh really, nice. No separate computer either? No separate power station, no house, no star wars? No something else we didn't ask for? Just one a toggle and you go? Whoaaaaaa.

Edit: lol even the skill itself is vibe coded:

Lightweight Chrome DevTools Protocol CLI. Connects directly via WebSocket — no Puppeteer, works with 100+ tabs, instant connection.

I feel like there's nothing fucking left on the internet anymore that is not some mean of whatever the LLM is trained to talk like now.

Someone already made a great agent skill for this, which I'm using daily, and it's been very cool! https://github.com/pasky/chrome-cdp-skill For example, I use codex to manage a local music library, and it was able to use the skill to open a YT Music tab in my browser, search for each album, and get the URL to pass to yt-dlp.

As long as it’s gated and not turned on by default, it’s all good. They could also add a warning/sanity check similar to “allow pasting” in the console.

Been using this one for a while, mostly with codex on opencode. It's more reliable and token efficient than other devtools protocol MCPs i've tried.

Favourite unexpected use case for me was telling gemini to use it as a SVG editing repl, where it was able to produce some fantastic looking custom icons for me after 3-4 generate/refresh/screenshot iterations.

Also works very nicely with electron apps, both reverse engineering and extending.
