Claude in Chrome: `save_to_disk` screenshots produce no file; `resize_window` no-op on maximized windows; no way to activate a tab
Environment: Claude Code desktop app on Windows 11 (Claude Fable 5.1), Claude in Chrome extension, Chrome 141.
mcp__claude-in-chrome__computerwithaction: "screenshot"andsave_to_disk: truereturns the image to the
model but no saved path and no file on disk (checked the session folders and Downloads). Same inside
browser_batch. The tool description says a path is returned.
mcp__claude-in-chrome__resize_windowreturns "Successfully resized window ... to 1400x985" but the window stays
maximized (window.innerWidth still 1920). Resizing only works once the window is restored via the OS.
- There is no tool to activate/select a tab in the MCP tab group.
navigate/tabs_create_mcpdo not bring the tab to
the front, so document.visibilityState stays "hidden".
Why it matters: to obtain PNG screenshots (plugin listing images for wordpress.org) the only working path was an OS-level
screen capture, which requires the tab to be the active tab of a visible window sized precisely; the user cannot use
Chrome meanwhile and has to click the tab manually. Some sites (Google Business Profile "Add update") only render
their forms when the tab is visible, so a "bring tab to front" tool would also unblock those flows.
Expected: save_to_disk writes the debugger-captured PNG (which already works on background tabs) and returns the path;resize_window restores a maximized window before resizing (or reports that it could not); a tabs_select tool (or anactive: true option on navigate) exists.
