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.
