Nutrient文書処理

Nutrient DWS APIを使用して、文書の変換、OCR、データ抽出、編集、署名、フォーム入力を実行します。PDF、DOCX、XLSX、PPTX、HTML、画像などを処理できます。

Nutrient文書処理 とは?

このスキルは、Nutrient DWS Processor APIを利用して文書処理タスクを実行するためのものです。PDFと主要なOffice形式(DOCX、XLSX、PPTX)、HTML、画像など幅広い入力をサポートし、形式変換やテキスト/表抽出、OCRによる検索可能なPDF生成、PII(個人識別情報)の編集、透かし追加、CMSデジタル署名、PDFフォームのデータ入力といった多様な操作が可能です。APIキーを環境変数に設定し、REST APIにマルチパートPOSTリクエストを送信する形で利用します。また、代替手段としてMCPサーバーを使ったネイティブツール統合もサポートしています。開発者にとっては、コマンドラインから簡単に文書処理を自動化できる強力なツールです。

MCPサーバー(代替方法)

ネイティブツール統合には、curlの代わりにMCPサーバーを使用します:

{
  "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"
      }
    }
  }
}

使用すべき場面

  • 文書の形式変換(PDF、DOCX、XLSX、PPTX、HTML、画像)
  • PDFからのテキスト、表、キー・バリューペアの抽出
  • スキャン文書や画像のOCR
  • 文書共有前のPII編集
  • 下書きや機密文書への透かし追加
  • 契約書や同意書へのデジタル署名
  • PDFフォームのプログラムによる入力
