When does this happen?

IF When connecting a browser instance to chrome-devtools-mcp, the MCP client gains full inspect, debug, and modify capability over all content in the browser and DevTools.

How others solved it

THEN Avoid sharing sensitive or personal information in the browser that you do not want exposed to the MCP client. This includes passwords, session tokens, private data displayed in DevTools panels, or browsing activity. Consider using isolated browser profiles for sensitive work.
