L10n.dev AI Localization Agent MCP

An MCP server that integrates AI-powered localization into coding agents, enabling format-safe translation of i18n files across 165 languages. It preserves keys, placeholders, and terminology using persistent glossaries and custom instructions, while performing server-side format checks and incremental updates to save quota and maintain consistency.
