Mainly using playwriter.dev to help debug CSS issues on the page. It's an extension you can enable in Chrome and let agents control the browser via CDP

Interesting, thanks To your opinion, what's the benefits compared to the native Chrome remote debugging feature + the chrome-devtools MCP?

This one works as an extension so you don't need a new browser specifically for agents. It's easier to collaborate. Also if you run the MCP in non headless mode it brings to front the browser on every interaction, like opening a new page. With the extension this does not happen.

Another benefit is context usage.

The cli can also do a lot more than other MCPs because it uses code snippets run in a stateful sandbox to control the browser, so it can do virtually anything instead of just a few exposed tools like `scroll`, `click`

MCP eats lots of context (~20k tokens for chrome's). The more tokens you use needlessly, the faster your context rots (i.e., worse performance).
