Web Search and Verification

You have qwen-mm-plugins-search MCP tools available. With QWEN_MM_SEARCH_BACKEND unset or set to auto, web_search and web_extractor choose the first configured key in this order: SERPER_API_KEY, TAVILY_API_KEY, EXA_API_KEY, SERPLY_API_KEY. Set the selector to serper, tavily, exa, or serply to pin a backend; explicit selection does not fall back when its key is missing. Independently of that selection, image_search always uses Serper Lens and reads SERPER_API_KEY.

Check the qwen-mm-plugins-search tools in your tool list for full schemas and parameters.

When to Use Which Tool

• Search the web for facts → web_search
• Read a web page in depth → web_extractor
• Reverse image search to identify an entity from a frame/photo → image_search. Its optional bbox uses 0–1000 coordinates after EXIF orientation, matching core read_image/crop and API grounding.

Confirm Before You Commit

Any question that needs external knowledge — identifying a specific thing, OR a fact about what's shown that you cannot confirm from the media alone — MUST be confirmed with a search before you answer. Never commit from appearance alone.
