LibreTranslate MCP — thin abstraction over any LibreTranslate-compatible instance.

Tools

• translate(text, target, source?, format?)
• detect_language(text)
• list_languages()

Auth / endpoint

LibreTranslate’s free public instances have largely shut down or migrated to paid. You must provide an instance:

• Self-host: https://github.com/LibreTranslate/LibreTranslate
• Paid: https://libretranslate.com (BYO their API key)
• Community instance that’s still up

Configure via:

• Platform: gateway env vars PLATFORM_LIBRETRANSLATE_ENDPOINT (URL) and optionally PLATFORM_LIBRETRANSLATE_KEY.
• BYO: pass ?_endpoint=https://your-instance/&_apiKey=... on the gateway URL.

Public instances (verified 2026-08-06)

Every free public instance this pack could have defaulted to is gone, so there is no keyless path. Checked on the date above:

Unconfigured, every tool now returns {found: false, reason: "requires_endpoint"} naming deepl_translate — rather than throwing, which booked as a tool error and was indistinguishable in the logs from the upstream being down. The pack is in the gateway’s BYO_ONLY_KEY_PACKS so routing sinks it below the translation tool that can answer without the caller’s key.

Tools

• translate — Translate text. Source can be “auto” to auto-detect. Returns translated text and the detected source (if applicable).
• detect_language — Detect the source language of a piece of text. Returns ranked language candidates with confidence.
• list_languages — List languages supported by the configured LibreTranslate instance.
