Description
Multilingual localization engine that brings i18n automation directly to AI assistants. Lingo.dev MCP translates code, content, and UI strings across frameworks like React, Vue, iOS, and Android. Instead of manually managing translation files, the server handles locale detection, string translation, and synchronization of translation catalogs — all through natural language instructions. Supports JSON, YAML, XLIFF, and other common i18n formats with context-aware translations that preserve placeholders and markup.
✅ Best for
Development teams building multilingual apps who want AI-powered i18n automation
