glot-i18n MCP

An AI-native internationalization (i18n) server that provides deterministic validation, lockfiles, and glossary-as-code for SaaS applications. It allows coding agents like Claude Code, Cursor, or Codex to access translation keys, usage contexts, and glossaries, while enforcing strict rules on placeholders, ICU syntax, and pixel width to ensure high-quality, safe translations.
