URI Let your Coding Agent debug the browser session with Chrome DevTools MCP

I have been using Playwright for a fairly long time now. Do checkout
JKolios wrote 2 min ago:
Now that there's widespread direct connectivity between agents and
browser sessions, are CAPTCHAs even relevant anymore?
tonyhschu wrote 6 min ago:
Very cool. I do something like this but with Playwright. It used to be
a real token hog though, and got expensive fast. So much so that I
built a wrapper to dump results to disk first then let the agent query
instead. [1] Will check this out to see if theyâve solved the token
burn problem.

I tell Claude to use playwright so I don't even need to do the setup
myself.

Similarly, cursor has a built in browser and visit localhost to see
the results in the browser. Although I don't use it much (I probably
should).

chrome-cli with remote developer port has been working fine this entire
time.

I donât do any serious web development and havenât for 25 years
aside from recently vibe coding internal web admin portals for back end
cloud + app dev projects. But I did recently have to implement a web
crawler for a customerâs site for a RAG project using Chromium +
Playwrite in a Docker container deployed to Lambda.
I ran the Docker container locally for testing. Could a web developer
test using Claude + Chromium in a Docker container without using their
real Chrome instance?

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.

I found this one working amazingly well (same idea - connect to
existing session):

Interesting. MCP APIs can be useful for humans too.
Chrome's dev tools already had an API [1], but perhaps the new MCP one
is more user friendly, as one main requirement of MCP APIs is to be
understood and used correctly by current gen AI agents.

Also works nicely together with agent-browser ( [1] ) using
--auto-connect

Was already eye rolling about the headline. Then I realized it's from
chrome.
Hoping from some good stories from open claw users that permanently run
debug sessions.

Someone already made a great agent skill for this, which I'm using
daily, and it's been very cool! [1] 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.
Do note that it only works for Chrome browsers rn, so you have to edit
the script to point to a different Chromium browser's binary (e.g. I
use Helium) but it's simple enough

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.
sheepscreek wrote 38 min ago:
As long as itâs gated and not turned on by default, itâs all
good. They could also add a warning/sanity check similar to
âallow pastingâ in the console.

Not the person you're replying to, but: I just use a separate,
dedicated Chrome profile that isn't logged into anything except
what I'm working on. Then I keep the persistence, but without
commingling in a way that dramatically increases the risk.
edit: upon rereading, I now realize the (different) prompt
injection risk you were calling out re: the handoff to yt-dlp.
Separate profiles won't save you from that, though there are other
approaches.
sofixa wrote 3 min ago:
Even without the bash escape risk (which can be mitigated with
the various ways of only allowing yt-dlp to be executed), YT
Music is a paid service gated behind a Google account, with
associated payment method. Even just stealing the auth cookie is
pretty serious in terms of damage it could do.

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 â 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.

What can you do? I mentioned the use of AI on another thread,
asking essentially the same question. The comment was flagged,
presumably as off topic. Fair enough, I guess. But about 80%
(maybe more) of posted blogs etc that I see on HN now have very
obvious signs of AI. Comments do too. I hate it. If I want to
see what Claude thinks I can ask it.
HN is becoming close to unusable, and this isnât like the
previous times where people say itâs like reddit or
something. It is inundated with bot spam, it just happens the
bot spam is sufficiently engaging and well-written that it is
really hard to address.
