nutrient-document-processing 是什麼?

此技能整合了 Nutrient DWS Processor API,讓 AI 代理能夠自動化處理文件生命週期中的常見任務。它支援將 DOCX、HTML 或圖片等多種格式轉換為 PDF,並能反向轉換為 DOCX 或 XLSX。技能內建 OCR 功能,可處理掃描文件並轉換為可搜尋的 PDF,支援超過 100 種語言。此外,還能進行模式或正則表達式為基礎的敏感資訊編輯(如 SSN、電子郵件)、添加浮水印、應用數位簽章(CMS),並透過程式填寫 PDF 表單欄位。所有操作通過單一 API 端點 (`https://api.nutrient.io/build`) 以 multipart POST 請求傳送 `instructions` JSON 完成。此技能適用於 Claude Code、Cursor 或 Codex 等支援 shell 命令或 MCP 伺服器整合的代理平台,使用者可選擇使用 `curl` 命令或設定 MCP 伺服器以獲取原生工具支援。

MCP 伺服器(替代方案)

如需原生工具整合,可改用 MCP 伺服器代替 curl:

{
  "mcpServers": {
    "nutrient-dws": {
      "command": "npx",
      "args": ["-y", "@nutrient-sdk/dws-mcp-server"],
      "env": {
        "NUTRIENT_DWS_API_KEY": "YOUR_API_KEY",
        "SANDBOX_PATH": "/path/to/working/directory"
      }
    }
  }
}

使用時機

  • 文件格式轉換(PDF、DOCX、XLSX、PPTX、HTML、圖片)
  • 從 PDF 中擷取文字、表格或鍵值對
  • 對掃描文件或圖片執行 OCR
  • 在分享文件前編輯 PII
  • 為草稿或機密文件添加浮水印
  • 合約或協議的數位簽署
  • 以程式方式填寫 PDF 表單
