Env: Claude Code 2.1.143 · Chrome 148.0.7778.168 · macOS 26.3.1 (25D771280a) · claude-in-chrome extension

Repro: Authenticate (Entra SSO+MFA) to a SharePoint Online site (*.sharepoint.com). From Claude Code, call mcp__claude-in-chrome__navigate or get_page_text on the authenticated tab.

Expected: page navigates / text returns. Actual: entire Chrome process tree crashes ("extension disconnected mid-operation"); Chrome must be relaunched. Reproducible 5/5 including on a freshly restarted clean profile with ample free RAM (66%).

Notes: tabs_context_mcp (tab-metadata only, no debugger attach) never crashes. Only operations that attach the Chrome debugger to the SharePoint page crash. Same failure on the site landing page and on a SitePages .aspx. Not memory-related (Chrome process tree collapses to ~5 MB / 0 helpers post-crash).
