next-intl-mcp-server provides MCP-compatible AI clients with deep, deterministic knowledge of next-intl — the leading i18n library for the Next.js App Router.

Instead of relying on boilerplate or expecting the AI to infer the correct API usage, this server offers purpose-built tools to transform components, detect inconsistencies across locale files, validate ICU syntax, and scaffold complete project setups — with or without URL-based routing.
