# Chrome DevTools MCP Cleanup

> Diagnose + clean up the recurring chrome-devtools-mcp wedge — multiple stale chrome-devtools-mcp@latest parent processes colliding on the shared ~/.cache/chrome-devtools-mcp/chrome-profile directory. Use when state-changing tools (newpage, navigatepage, selectpage, takesnapshot) error with "The browser is already running for /Users/.../chrome-profile. Use --isolated to run multiple browser instances." while listpages still works. Card 223 (CvjIx0qZ).
