Feature Request: Support Capturing Network Requests Across Page Navigation

[thoughtentity]

Chrome DevTools MCP should support capturing network requests across page navigations. This would allow the MCP to capture network requests that occur during a redirect. This would enable additional debugging scenarios, such as allowing the LLM to observe and debug logout flows where the authentication cookies are cleared in a transient redirect response.

The current network tools only allow listing network requests for the currently loaded page, which means that transient network requests, such as redirects across pages, get missed.

Your point is valid nevertheless classic workaround is to use evaluate script or build an extension and use console message

Thank your for the feature request.

This could work similar as https://github.com/ChromeDevTools/chrome-devtools-mcp/blob/main/docs/tool-reference.md#performance_start_trace, but for the network.

Edit: What would be the prompt you would use in your MCP client/AI agent to start such journey? Do you have example workload?

Nice issue. I think it would also be great if we could also persist console.log() messages across page navigation / redirections, as well as persisting network logs.
