Browser Automation

Claude in Chrome gives Claude Code full browser automation, but blocks 58 domains (banks, Tinder, Reddit, Robinhood, Bloomberg) and only works in Chrome/Edge. I reverse-engineered it from the tool schemas. Same 18 tools, same performance. No blocklist. Any Chromium browser. Open source.

Claude in Chrome gives Claude Code full browser automation: 18 MCP tools for clicking, typing, screenshots, JS eval, accessibility tree, console/network monitoring, and more. But it blocks 58 domains across 11 categories (banks, brokerages, Tinder, Reddit, Robinhood, Bloomberg, Coinbase) and only works in Chrome and Edge. Open Claude in Chrome is a clean-room reverse engineering of the official extension. Same 18 tools, same performance, 100% parity. Claude doesn't know the difference because it was trained on these exact tool schemas. The only differences: - No domain blocklist. Navigate anywhere. - Works in any Chromium browser (Brave, Arc, Opera, Vivaldi, Edge, Chrome). - Fully open source (MIT). ~2,200 lines of JavaScript. Built from the MCP tool schemas, not a fork.

@sebastian_sosa1 why not just block the domains in Claude’s allowed domains list in chrome’s extension settings?

@chrismessina
"open-claude-in-chrome" is designed to remove restrictions not to add them (although since it is open source you are more than welcome to ), the default "Claude in Chrome" blocks domains, "open-claude-in-chrome" removes that constraint (along with the browser constraint).

Sorry maybe I don't understand the premise of the question or I didn't communicate things well.

@chrismessina that would be counterproductive to what he built it for.
