Getting Started

1. Add the server to your MCP client. For Claude Code: `claude mcp add babelize -e ANTHROPIC_API_KEY=sk-ant-... -- npx -y @babelize/mcp` 2. Open your app's repo and ask your agent: "Make this app global-ready in German and Japanese." 3. The agent runs `babelize_analyze` → `babelize_translate` → `babelize_check` and reports what changed. Analyze, check and review need no key. Translate needs one of ANTHROPIC_API_KEY, OPENAI_API_KEY, GEMINI_API_KEY, GROQ_API_KEY, OPENROUTER_API_KEY, or a free-tier BABELIZE_API_KEY (https://app.babelize.co/api-keys).

Functions this server exposes to AI clients

babelize_analyze

Localization readiness report: framework, i18n setup, hardcoded strings (file:line), hardcoded dates/currencies/plurals, locale coverage, unused keys. Dry run, changes nothing.

babelize_translate

Extracts strings, wires them to next-intl or react-i18next, translates into target locales and writes locale files. Incremental via a lockfile.

babelize_check

QA of locale files: missing, stale or empty keys, untranslated values, lost placeholders, invalid ICU, wrong plural forms.

babelize_review

The same QA, limited to locale entries changed in the git diff.
