DeepL API MCP — high-quality machine translation. Free tier 500k chars/mo.

Auth

• Bring your own key (Bruce, 2026-11-02, fleet #3861): pass your DeepL key as ?_apiKey=…. Pipeworx does not supply one; without a key every tool refuses with “DeepL requires an API key”. Free keys at DeepL’s API page.
• Free-tier keys end with :fx (auto-detected → free endpoint).
• For translation with no key of your own, call mymemory_translate (the mymemory pack) — keyless outright. The gateway also falls back to it automatically on a DeepL quota error (fleet #3862).

Tools

• translate(text, target_lang, source_lang?, split_sentences?, preserve_formatting?, formality?, glossary_id?, tag_handling?, outline_detection?, non_splitting_tags?, splitting_tags?, ignore_tags?) — translate text (one or many strings)
• usage() — current month’s usage + limits
• source_languages() — supported source languages
• target_languages() — supported target languages
• glossary_language_pairs() — supported glossary language pairs

text accepts a string or array of strings. target_lang: e.g. EN-US, DE, JA, ES, FR. formality: default | more | less | prefer_more | prefer_less.
