• mcp2brave.py:464-474 (handler)

  Handler function for the 'search_news_info' MCP tool. Registered via @mcp.tool() decorator. Takes a query string and delegates to the internal _do_news_search helper.
  @mcp.tool() def search_news_info(query: str) -> str: """使用Brave新闻API搜索新闻 参数: query (str): 新闻搜索关键词 返回: str: 新闻搜索结果，包含标题、来源、日期和描述 """ return _do_news_search(query)
• mcp2brave.py:356-417 (helper)

  Core helper function implementing the news search logic: constructs API request to Brave News API, parses response, formats results with title, source, date, URL, description. Handles language detection, errors.
