Prerequisites (What You Need)
Accounts
A valid Claude.ai account and an Xdoc account with API access enabled.
Files

Step-by-Step: Translate English to Chinese
Step 1: Setup Xdoc Translation MCP Server in Claude
Begin by integrating the professional translation engine into your Claude environment.
- Open Claude settings and navigate to the Connectors tab.
- Click on Add Custom Connector to initiate the setup.
- Enter the MCP server URL:
https://translation.x-doc.ai/mcp. - Complete the OAuth authorization using your Xdoc credentials.
Success: You will see "Xdoc Translation" listed as an active connector.
Common Mistake: Forgetting to create an "Authentication User" in the Xdoc API management dashboard before trying to log in via Claude.
Step 2: Execute Document Translation
Once connected, you can translate entire files using natural language prompts.
- Claude will provide a secure upload link via
get_upload_page_url. - Upload your file in the browser window that opens.
- Claude automatically triggers
translate_documentwithsource_language="en"andtarget_language="zh-cn". - The system polls the status until the high-accuracy translation is ready for download.
Success: A download link for the translated .docx file appears in the chat.
Common Mistake: Closing the Claude chat window before the translation status reaches 100%.
Step 3: Programmatic Configuration (Optional)
For developers using Claude Desktop or Claude Code, use the API key for local configuration.
{
"mcpServers": {
"xdoc-translation": {
"type": "streamable-http",
"url": "https://translation.x-doc.ai/mcp",
"headers": {
"x-api-key": "sk_your_api_key_here"
}
}
}
}
Success: Claude Desktop will now have the translation tools available in every session.
Common Mistake: Using the standard account password instead of the specific API Key in the headers.
Validation Checklist (Make Sure It Worked)
Common Issues & Fixes
| Problem | Cause | Fix |
|---|---|---|
| Authentication Failed | Incorrect credentials or expired token. | Re-generate the Authentication User in Xdoc API Management. |
| File Upload Error | File size exceeds 20MB limit for standard mode. | Use the "Deep Translation" mode or compress the file. |
| Terminology Inconsistency | Glossary not attached to the task. | Ask Claude to "use my Medical Terms glossary" during the prompt. |
Best Practices (Do It Right Long-Term)
Leverage Glossary Management: Always create a terminology library for domain-specific projects to ensure "cardiovascular" is always "心血管" across all files.
Use Translation Memory: Enable memory libraries to reuse previously translated sentence pairs, which significantly reduces costs and improves consistency.
Optimize for Technical Documents: When you translate technical documents with AI, use the "Deep" mode for better contextual understanding.
Verify with Typesetting: For publication-ready files, utilize the best translation API for product manuals which includes format preservation.
