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

Auth

• Platform: PLATFORM_DEEPL_KEY. BYO: ?_apiKey=….
• Free-tier keys end with :fx (auto-detected → free endpoint).
• translate is currently refused on the Pipeworx shared key (HTTP 456), and it is not a character quota: measured 2026-08-28, usage on the same key answers character_count: 0 against a full character_limit while translate 456s in the next call. Zero successes in the seven days before that. Waiting does not clear it — pass your own key as _apiKey. The read-only tools (usage, source_languages, target_languages, glossary_language_pairs) still answer on the shared key. Fleet #577.

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)

• target_languages() — supported target languages
• glossary_language_pairs() — supported glossary language pairs
