What can the browser show about your own demo page?

Developer tools can show when a page loads a file and what happened during the load. You can use that information to explain a slow demo without guessing from the appearance alone. Check that the trace belongs to your owned page and compare it with what you observe in the browser.

What does attaching a browser expose?

Chrome’s project says an MCP client may inspect and modify data in the connected browser and its developer tools. Choose a clean browser profile reserved for the demo. Check the server’s data collection settings, which may include usage statistics or separate features. Avoid personal tabs and sign-ins.
