Ai MCP Server — l10n-dev/ai-l10n

MCP Server that turns your AI agent into a localization expert with token-efficient i18n translation

What the server does

AI-powered translation for app localization. Automatically translate your i18n files to 165 languages using AI. Supports JSON, JSONC, Flutter ARB, YAML, PO, XLIFF, and all other text-based localization formats with intelligent project structure detection.

• 🤖 165 languages — context-aware AI translation, not word-by-word machine output
• 🎯 Any text-based format — JSON, JSONC, Flutter ARB, Shopify themes, YAML, PO (gettext), XLIFF, and more (full list)
• 📁 Zero setup — target languages are auto-detected from your file and folder layout
• 🔄 Incremental by default — --update translates only new and changed strings and leaves the rest untouched
• 🛠️ Nothing breaks — placeholders, HTML tags, and formatting are preserved; dates and numbers are localized; proper names, URLs, and technical terms are left alone (how it works)
• 🌐 Correct plural forms — every i18next suffix is generated, including complex rules in Russian, Arabic, and Polish
