Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| web_fetchB | Read one public HTTP(S) URL and return clean LLM-friendly Markdown. render='auto' starts with a lightweight static fetch, escalates to Crawl4AI for JavaScript rendering when content appears incomplete, then uses Scrapling stealth as the final fallback. Use render='always' for known JavaScript-heavy pages. |
| web_crawlC | Crawl a bounded set of internal pages from one public website. Uses Crawl4AI breadth-first crawling. External links are not followed. The server enforces hard caps on depth/pages regardless of the requested values. |
| web_extractA | Extract repeated elements from a public webpage using a CSS selector. If attribute is omitted, visible text is returned. In auto mode Scrapling tries static HTTP first, then a dynamic browser, then stealth browser retrieval. |
| web_searchA | Search the public web through Firecrawl. Requires FIRECRAWL_API_KEY. category can target GitHub/research/PDF/developer sources; time_filter limits results to the past hour/day/week/month/year. |
