谷歌發佈開源Python庫LangExtract，利用Gemini等大模型從非結構化文本中提取結構化信息。核心功能包括精準溯源、可靠結構化輸出、長文檔優化、交互式可視化和多模型支持。適用於醫療、文學研究和商業情報等領域，如從病歷提取關鍵信息、分析文學作品人物關係等。該工具無需微調即可適配不同領域，顯著降低技術門檻。項目地址：github.com/google/langextract
LangExtract MCP Server是一個基於FastMCP的服務器，通過Google Gemini模型從非結構化文本中提取結構化信息，為Claude Code等AI助手提供文本信息提取能力，支持智能緩存和持久連接。
