Common questions about connecting and running Chrome DevTools.
What is the Chrome DevTools MCP server?
It's an MCP server that exposes Chrome DevTools Protocol capabilities, allowing you to control and inspect Chrome browsers programmatically. You can automate testing, capture screenshots, execute scripts, and debug web applications through Claude or other AI assistants.
How do I install and run this server?
Install via npm with `npx chrome-devtools-mcp@0.25.0`. The server uses stdio transport, so it communicates with your MCP client through standard input/output streams.
Do I need Chrome running before connecting?
Yes, you need a Chrome instance running with DevTools Protocol enabled. The server connects to an existing Chrome process; it does not launch Chrome itself.
What can I automate with this server?
You can take screenshots, execute JavaScript, inspect the DOM, monitor network requests, control navigation, and interact with page elements—essentially anything DevTools Protocol supports.
Is there a cost or rate limit?
This is an open-source MCP server with no built-in rate limits or costs. Limitations depend on your Chrome instance and the DevTools Protocol itself.
