Open Claude in Chrome drops blocklist
Open Claude in Chrome is a clean-room, open-source reimplementation of Anthropic’s Claude in Chrome browser automation stack. It keeps the same 18 MCP tools and performance profile, but removes the 58-domain blocklist and runs on any Chromium browser.
// ANALYSIS
This is a sharp example of product cloning by protocol archaeology: the value isn’t just “open source,” it’s that the exact workflow can be reproduced without Anthropic’s policy constraints.
- –The project targets a real pain point for power users: Anthropic’s browser automation is useful, but the blocklist makes it less general-purpose than it first appears.
- –Supporting Brave, Arc, Opera, and other Chromium browsers makes the tool feel more like infrastructure than a one-off hack.
- –The repo’s claim of identical tool coverage and performance is the key risk and the key appeal; if it holds up, this becomes a credible alternative for advanced users.
- –It also raises a prompt-injection and safety question: removing site restrictions increases capability, but also increases exposure when agents browse the open web.
