Chrome DevTools MCP gives coding agents access to Chrome's inspection and debugging capabilities. It helps an agent examine the running website, connecting what the code says with what the browser actually displays and requests.
Investigate browser-side problems
Inspect console output, network activity, and page state when a feature works differently in the browser than expected from the source code.
Check a change against the running page
Use browser inspection and performance tools to evaluate a product change. This is useful for UI bugs and slow interactions that require runtime evidence.
