Summary
Plugs translation management directly into Claude and other AI coding tools via MCP. Exposes operations like find_orphan_keys, translate_missing, add_translations, and rename across all locale files at once. Particularly useful when your agent is building features that span multiple locales: it can write new keys, detect what's untranslated, and kick off translation sampling with your project's glossary and tone rules already loaded as context. Auto-detects Nuxt, Laravel, or generic JSON/PHP setups. Pairs with a CLI for terminal use. Handles layered translation architectures and includes a reportOutput mode that writes large responses to disk instead of flooding context windows.

A GitHub Action and a GitLab CI template ship from this repository too.
Quick Start
npm install -g @the-i18n-kit/cli
the-i18n-cli init # write a config from what it detects
