Which MCP Server Should You Choose?
Choose Kaeris MCP when:
You need dedicated capabilities in the Translation Services domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
AI localization: translate an app's string files into 46 languages (JSON, .arb, .po, .strings, Android XML, …) with placeholder-safe, reproducible output — from Claude/Cursor.
Brings SMART consensus translation into any MCP client. Runs your text through 22 leading AI translation models at once and returns only the output the models agree on, so you get a confidence-backed result instead of a single engine's guess. Exposes two tools: smart_translate (text, source language, target language) and list_languages (all supported language codes). Hosted remote server at https://www.machinetranslation.com/mcp over streamable HTTP — no install, no API key, just connect the URL and sign in. Built for translators, localization and content teams, marketers, and developers.
Tools & Capabilities Breakdown
Kaeris MCP Tools (7)
kaeris_scan_repo
Discover a repo's i18n setup: locale files found, base language, target languages, framework guess (i18next/next-intl/vue-i18n/Flutter/Android/iOS/gettext/generic)
kaeris_status
Completeness/health per target locale — missing keys, extra keys, placeholder mismatches, plus the quality detectors that gate a merge in CI: number drift, lost inline tags, broken entities/escapes, ICU/CLDR plural gaps (same verdict as `kaeris check --json`)
kaeris_list_missing_keys
The exact missing/broken keys (with source text) for one target locale, so an agent knows exactly what to fix
kaeris_list_languages
List all supported target languages
kaeris_translate
Translate inline strings → per-language results, with QA (placeholder-loss & UI-overflow flags; `verify=True` back-translates to check meaning)
