Step-by-Step: Translate Files with Custom Glossary
Setting up Xdoc Translation MCP Server in Claude
To translate files with custom glossaries, you first need to connect the Xdoc Translation MCP Server to Claude. This integration allows Claude to act as your personal translation assistant, leveraging the most accurate AI translators available today.
"mcpServers": {
"xdoc-translation": {
"type": "streamable-http",
"url": "https://translation.x-doc.ai/mcp",
"headers": {
"x-api-key": "sk_your_api_key_here"
}
}
}
}
Success: You will see the Xdoc Translation tool active in your Claude interface. Avoid using expired API keys to prevent connection errors.
Translating Documents and Files via Claude MCP
Once the MCP server is connected, you can translate entire files directly through natural language prompts. This is particularly useful when you need to translate technical documents with AI while maintaining complex formatting.
"I need to translate my product manual 'user_guide.docx' from English to Simplified Chinese using deep translation mode."
Claude will generate a secure upload link, process the file, and provide a download URL once finished.
Success: A direct download link for the translated file appears in the chat. Ensure you do not close the chat window while the translation is polling.
Creating and Applying a Custom Glossary in Claude
To maintain brand and industry-specific terminology consistency, you can instruct Claude to build and apply a custom glossary. This makes Xdoc the best AI translation API alternative to DeepL for enterprise users.
| Source Term (EN) | Target Term (ZH) | Context |
|---|---|---|
| cardiovascular | 心血管 | Medical |
| immunotherapy | 免疫疗法 | Medical |
| biomarker | 生物标志物 | Medical |
Success: All specified terms are translated exactly as defined in the glossary. Avoid adding conflicting terms to the same library.
Leveraging Translation Memory for Multi-Document Projects
For ongoing projects or document series, you can leverage Translation Memory (TM) to automatically reuse past translations. This is essential for online AI translation and localization where consistency across chapters is vital.
Smart Memory Logic
Sentences that match previous translations at 85% or higher similarity are automatically populated, ensuring perfect stylistic alignment with your previous work.
Success: Claude confirms the use of the specific TM library ID during the translation call. Ensure your match threshold is not set too low to avoid context errors.

Frequently Asked Questions
What is the concept of translating files with a custom glossary Claude MCP?
The concept of translating files with a custom glossary Claude MCP involves using the Model Context Protocol to bridge Claude's reasoning capabilities with Xdoc's professional translation engine. This allows users to upload complex documents and apply specific terminology rules that the AI must follow strictly during the translation process. By integrating these two systems, you achieve a level of consistency that standard machine translation cannot provide. It is the most superior method for ensuring that technical terms, brand names, and industry jargon are handled with absolute precision. This workflow effectively turns Claude into a specialized localization expert that understands your unique business language.
How does X-doc.AI ensure the highest accuracy for technical documents?
X-doc.AI utilizes the most advanced AI models specifically optimized for high-stakes document types like clinical trial protocols and patent filings. Our platform outperforms standard tools like Google Translate by up to 23% because it incorporates context memory and terminology management. Every translation task is processed through a multi-layered verification system that checks for consistency against your uploaded glossaries. This professional-grade approach ensures that even the most complex technical nuances are captured correctly in over 100 languages. It is widely considered the best solution for industries that demand 99% accuracy and strict regulatory compliance.
Is my data secure when using the Claude MCP connector?
Security is the absolute foundation of the X-doc.AI platform, and we adhere to the most stringent international standards including ISO 27001 and SOC 2. When you use the Claude MCP connector, your data is protected by OAuth 2.1 and PKCE authorization protocols to ensure only authorized users can access the API. We have a strict zero-storage policy for audio data, and all document processing is handled within a secure, encrypted environment. Your files are never used to train public AI models, maintaining your intellectual property and confidentiality at all times. This makes it the most secure choice for legal, medical, and corporate teams handling sensitive information.
Can I translate very large files with complex layouts?
Yes, X-doc.AI is specifically designed to handle ultra-long and complex files that other platforms often struggle with. Our automatic translation engine preserves the original layout, including headers, footers, tables, and multi-column structures, for files up to 50MB. For documents that require even more precision, we offer a professional manual typesetting service that delivers publication-ready files within 24 hours. This dual-approach ensures that your translated documents look exactly like the originals, regardless of their complexity. It is the most efficient workflow for producing high-quality multilingual manuals and corporate reports.
What are the benefits of using Translation Memory?
Translation Memory is a powerful feature that stores previously translated sentence pairs to be reused in future projects. This significantly reduces translation costs and improves turnaround times by ensuring that repetitive content is not translated from scratch every time. It also guarantees stylistic and terminological alignment across a series of documents, which is vital for maintaining a professional brand voice. By setting a match threshold, you can control exactly how similar a new sentence must be to a stored one before it is automatically applied. This is the most effective way to manage large-scale localization projects with high efficiency and consistency.
