MCP 服务器（替代方案）

对于原生工具集成，可以使用 MCP 服务器代替 curl：

json
{
  "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"
      }
    }
  }
}

何时使用

  • 在不同格式之间转换文档（PDF, DOCX, XLSX, PPTX, HTML, 图像）
  • 从 PDF 中提取文本、表格或键值对
  • 对扫描文档或图像进行 OCR
  • 在共享文档前脱敏个人身份信息（PII）
  • 为草案或机密文档添加水印
  • 为合同或协议进行数字签名
  • 以编程方式填充 PDF 表单
