FAQs

Q: Does this send my browser data to a third-party server?
A: No, the server operates completely on your local machine. All communication happens directly between the Chrome extension and the AI client on your computer, ensuring your data stays private.

Q: Why is the mcp-chrome-bridge package necessary?
A: The bridge serves as a local intermediary. Chrome extensions have security restrictions that prevent them from directly opening network ports that other applications can connect to. The bridge listens for connections from your AI client and safely relays commands to the extension.

Q: How is this better than a Playwright-based MCP server?
A: The main advantage is that Chrome MCP Server uses your personal browser instance. Playwright-based servers launch a new, clean browser process for each session. This means you have to log in to websites every time. With this server, the AI can automate tasks on sites where you’re already logged in, using your existing cookies and settings.

Q: Can I use this with AI assistants other than Claude?
A: Yes, any AI system that supports the Model Context Protocol can connect to this server. The server is model-agnostic and works through the standard MCP interface.
