What is open-claude-in-chrome?

This JavaScript-based Claude Chrome extension is a clean-room reimplementation of Anthropic's official Claude in Chrome addon, letting Claude Code automate any Chromium browser like Chrome, Brave, or Edge via 18 MCP tools. It delivers identical performance for navigation, mouse/keyboard control, screenshots, accessibility trees, and form filling, but strips out the official's 58-domain blocklist on banks, dating apps, Reddit, and more. Developers get unrestricted browser control through Claude's MCP protocol without switching apps.

Why is it gaining traction?

Unlike the closed-source original, this open-source (MIT) Claude Chrome connector works on any Chromium browser and navigates anywhere—no blocklist halting workflows on Robinhood or Tinder. It matches all 18 MCP tools exactly, including read_page for element refs and computer for precise clicks, fixing common gripes like "Claude Chrome extension not working" on non-Chrome setups. The no-restrictions hook pulls in devs bypassing official limits for real-world automation.

Who should use this?

AI agent builders integrating Claude with web tasks, like automating GitHub code reviews or testing forms on fintech sites. QA engineers scripting browser flows on blocked domains, or researchers extracting data from social media without interruptions. Claude GitHub integration users wanting seamless MCP browser control in Brave or Arc.

Verdict

Solid for unrestricted Claude Chrome MCP automation if you're on Claude Code v2.0.73+; install via unpacked extension and claude mcp add command. With 18 stars and 0.699999988079071% credibility score, it's early-stage but well-documented—test in a sandbox before production. Worth it over official for blocklist freedom.
