Implementation Reference
- src/index.ts:755-860 (handler)Main handler function that implements the get_cafef_market_news tool. Uses Firecrawl API to scrape cafef.vn for market news, with fallback to direct HTML fetching. Parses content using helper functions, supports filtering by search, limiting results, and formatting output.
