Claude in Chrome (serveur MCP)
The `claude-in-chrome` MCP server built into Claude Code and switched on by the `--chrome` flag: it goes through the Claude in Chrome extension and lets Claude navigate, click, fill forms, read the console and take screenshots in your browser, with the sessions you are already signed into. It is the tool side of the concept of the same name, which describes the feature.
Strengths
- Automates visual verifications, Claude screenshots and validates the UI without human intervention
- Full DOM access, can read states, attributes, and contents for precise validation
- Plugs naturally into a plan step that asks for human visual verification
Limitations
- Requires a Chromium browser open with the extension and a direct Anthropic plan: unavailable under WSL and through Bedrock, Google Cloud or Microsoft Foundry
- Risk of unintended actions if Claude misinterprets navigation instructions
Best for
- Automating visual verifications in a milestone-based workflow
- UI acceptance tests without maintaining a separate Playwright suite
- Interactive debugging of a web application directly from Claude Code
