I18n

This server gives Claude native i18n operations through six tools that cover the typical localization workflow. You can detect languages in text with confidence scores, extract hardcoded strings from JSX/HTML/JS that need translation keys, analyze translation JSON files for missing keys and interpolation mismatches across locales, generate CLDR plural rules for 15+ languages, and format numbers, currencies, dates, and relative times using Intl APIs. Reach for this when you're internationalizing a codebase and want Claude to audit your translation files, suggest i18n keys for strings it finds, or help you understand why Russian needs four plural forms while Japanese needs one.
