Gemini web media analysis
Attaches a local image or video to the Gemini web composer and reads the reply. Verified working on gemini.google.com/app, Chrome, signed-in account, 2026-08-15.
Needs the claude-in-chrome MCP server — navigate, find, file_upload, computer, javascript_tool, get_page_text — and a Chrome profile already signed in to Gemini. No API key.
Two different paths. Use the right one:
| Media | Path |
|---|---|
| Video | find Gemini's own hidden input → file_upload into it → real click on the composer. See Video path |
| Image | Helper input → synthetic paste event. See Image path |
Never click "Dateien hochladen" / "Upload files" in the uploads menu. It opens the native OS file dialog, which blocks the whole automation session — no further tool call reaches the browser until a human dismisses it by hand.
