Lantis

Lets a coding agent find, translate, validate and review an app's existing localization files (Android strings.xml, Apple String Catalogs, gettext) directly in the repo, supplying code usage, comments, glossary and voice notes as context. Placeholders, plural forms, escaping and markup are checked in code before any translation is written, and results land as reviewable drafts that never overwrite hand edits or approved work.

This MCP gives you full control over your translation projects from start to finish. You can log in anytime to see what stage your project is in — whether it’s being translated, reviewed, or completed.

The i18n cycle of a JavaScript project as tools: extract the texts written in code, list missing translations and write machine translations as drafts that a person approves. Works with React, Vue, Svelte, Next.js, Nuxt, SvelteKit and Astro.

Translates text, detects languages, and compares translations across multiple languages using a built-in phrase dictionary.
