analyze_screenshot
Capture a screenshot of any public URL and analyze it with a local vision model to answer questions about the page. Supports full-page captures for detailed inspection.
Instructions
Take a screenshot of a URL in a headless browser and analyze it with a local Ollama vision model. Good for public pages. For pages requiring login, use capture_window instead. Use full_page: true to capture content below the fold — the page is sliced into segments and sent as multiple images so no detail is lost.

|---|---|---|---|
| url | Yes | URL to screenshot (e.g. http://localhost:3004) | |

| wait_ms | No | Milliseconds to wait after page load for JS rendering | |
| question | Yes | What to analyze or look for in the screenshot | |
