## Description

This Connector bridges your account with your AI agent to handle high-quality translations without switching tabs or manual data entry. Instead of copy-pasting blocks of text into a browser and hoping for the best, you can just ask your agent to translate a paragraph, a marketing slogan, or a complex technical document. It handles the heavy lifting of neural machine translation while respecting specific nuances like formal versus informal tones, which is critical for maintaining a professional image. If you need to stick to specific brand terms, the Connector pulls from your custom glossaries to ensure that "Dashboard" always stays "Tableau de Bord" and never gets swapped for a generic term. You can manage these glossaries, check your character usage, and monitor document translation progress right from your chat interface. It's a huge time saver for anyone who needs to move content across languages quickly without losing the soul of the original message. This is especially helpful for companies that need to scale their presence into new markets while keeping their brand identity intact. By adding this to your setup via the Vinkius catalog, you get a professional-grade translation pipeline that feels like a natural part of your conversation with your agent. You no longer have to worry about inconsistent terminology or tone shifts that can happen with generic tools.

## Frequently Asked Questions

**Can DeepL MCP handle different tones for my content?**
Yes, it can. You can specifically ask your agent to use formal or informal tones, which is helpful for making sure your social media posts sound friendly while your business documents stay professional.

**How does the DeepL glossary feature work?**
It allows you to set specific translations for your brand terms. For example, you can ensure your product names always stay the same in every language, preventing the AI from using generic alternatives.

**Can I see my DeepL API usage through the Connector?**
Yes, you can ask your agent to check your character usage at any time. It will show you how much of your quota you have left and when your billing period resets.

**Does DeepL MCP support many languages?**
It supports over 30 languages, including major global languages and many others. You can ask your agent to list all available target languages whenever you need to check.

**How do I check the status of a large document translation?**
When you submit a large document for translation, you can ask your agent to check the status. It will tell you how far along the process is so you don't have to wait around wondering.

**Is this good for keeping brand consistency?**
It is specifically designed for that. By using the glossary tools, you ensure that your unique brand terms are never lost or changed during the translation process.

**Can I control the formality of translations (formal vs. informal)?**
Yes! Use `translate_formal` for professional communications (e.g., contracts, official correspondence) or `translate_informal` for casual content (e.g., social media, chat). The standard `translate_text` tool also accepts an optional formality parameter ('more', 'less', or 'default'). Note: formality control is available for select target languages including DE, FR, ES, PT-BR, and others.

**Can I create custom glossaries to ensure consistent terminology?**
Yes. Use `create_glossary` with a name, source language, target language, and TSV entries (tab-separated source→target pairs). Then use `translate_with_glossary` to apply the glossary during translation. Use `list_glossaries` to see all glossaries, `get_glossary_entries` to inspect term pairs, and `list_glossary_language_pairs` for supported combinations.

**How does DeepL authentication differ from standard Bearer tokens?**
DeepL uses a custom Authorization header format: `DeepL-Auth-Key YOUR_KEY` (not Bearer). Your API key is generated from the DeepL account dashboard. Free accounts use `api-free.deepl.com`, while Pro accounts use `api.deepl.com`. Use `get_usage` to check your current character consumption and plan limits.
