Proposed fix: [Chrome 136+ / agents attaching to 'my Chrome'] --remote-debugging-port ignored on the default profile: 'DevTools remote debugging requires a non-default data directory. Specify this usi
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Launch Chrome with --remote-debugging-port=<port> --user-data-dir=<separate dir> (sign in there once), or use Chrome for Testing/Chromium; for attaching to the live default profile use Chrome 144+'s chrome://inspect/#remote-debugging permission flow (chrome-devtools-mcp --autoConnect) or a browser extension bridge (e.g. Playwright MCP --extension).
Option: Use a dedicated user-data-dir for the debug Chrome [evidence: documented_workaround]
Applies when: Any CDP attach flow
Steps:
1. Quit Chrome
2. Start: chrome --remote-debugging-port=9222 --user-data-dir=<new dir>
3. Point the agent at http://127.0.0.1:9222
Expected: CDP endpoint available
