Chrome MCP: Debugger detaches on complex pages, breaking screenshot/coordinate actions

Description

The Chrome debugger API connection used by mcp__claude-in-chrome__computer (screenshot, coordinate-based click/scroll/zoom) repeatedly detaches when interacting with complex pages (e.g., Wikipedia articles). Content-script-based tools (read_page, find, form_input, javascript_tool, ref-based clicks) remain stable.

Steps to Reproduce

1. Connect Claude Code CLI to Chrome via the native host MCP bridge
2. Navigate to a complex page like https://en.wikipedia.org/wiki/Raspberry_Pi
3. Use read_page, find, form_input, javascript_tool — all work fine
4. Attempt computer with action: screenshot — fails with:

• "Error capturing screenshot: Detached while handling command."
• Or "Browser extension is not connected."

1. Coordinate-based scroll, zoom, and left_click also fail after detachment
2. Eventually the entire extension connection drops and cannot reconnect without manual intervention (clicking extension icon or restarting Chrome)

Observed Behavior

• Stable tools (content script API): tabs_context_mcp, tabs_create_mcp, navigate, read_page, find, form_input, javascript_tool, get_page_text, read_console_messages, read_network_requests, resize_window, shortcuts_list, switch_browser, ref-based left_click/scroll_to/hover/key/type
• Unstable tools (debugger API): screenshot, coordinate-based left_click/scroll/hover/zoom, gif_creator export
• Simple pages like example.com work fine for screenshots; complex DOMs (Wikipedia) trigger detachment
• After repeated detachments, the extension fully disconnects and tabs_context_mcp also fails
• Reconnection requires manual user action in Chrome

Expected Behavior

Screenshot and coordinate-based actions should work reliably on any page, or gracefully recover/reconnect when the debugger detaches.

Environment

• Claude Code version: 2.1.41
• OS: Ubuntu Linux 6.8.0-100-generic
• Chrome: latest stable
• Extension: Claude browser extension (latest)

Workaround

Use ref-based interactions exclusively from CLI (read_page → find → click by ref), avoiding screenshot and coordinate-based actions entirely.

Feature Request

Consider adding a "relay mode" where MCP tool calls route through the Chrome extension side panel instead of attaching the debugger directly. The side panel's browser automation is reportedly stable even on complex pages. This would allow CLI to delegate visual/debugger-heavy tasks to the side panel and read results back via stable content-script tools.
