Step-by-Step: Integrate and Translate

1

Connect Xdoc Translation MCP Server

To begin, you must link the translation engine to your Claude environment. Visit the Claude MCP Directory and locate the Xdoc Translation connector. This integration allows Claude to access online AI translation capabilities directly within your chat interface.

Connect Claude MCP

Success: You will see a "Connected" status in your Claude settings. Avoid skipping the OAuth step, as it is required for secure file handling.

2

Generate API Credentials

Navigate to your Xdoc API Management dashboard. Here, you will create a unique API Key and an Authentication User. This is essential for the fastest file translation API performance.

API Management Create API Key

Success: Your API key will be visible in the "My API" section. Ensure you copy the key immediately as it may be hidden for security later.

3

Execute the Translation Workflow

Simply prompt Claude: "I need to translate my PDF from English to Simplified Chinese." Claude will generate a secure upload link. Once you upload the file, the MCP server handles the heavy lifting, ensuring technical documents are translated with AI while preserving every table and image. 

{
  "mcpServers": {
    "xdoc-translation": {
      "type": "streamable-http",
      "url": "https://translation.x-doc.ai/mcp",
      "headers": {
        "x-api-key": "sk_your_api_key_here"
      }
    }
  }
}

Success: Claude will provide a final download link for your translated document. Do not close the chat until the "get_translation_status" returns "complete".
