Frequently asked questions
Do I need a Duolingo account to use this?
No! Public endpoints like user profiles, version info and dictionary hints work without authentication. Just provide a username to look up. For private data (your own progress, store items), you'd need to be logged into Duolingo.
What languages are supported?
Duolingo supports 40+ languages including English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese, Hindi and many more. Use get_version_info to see the full list of supported language codes.
Can I get my full learning progress?
The public API returns limited profile data. For full progress including individual skill levels and detailed stats, you need to be authenticated with your Duolingo session. The username-based endpoint returns basic info like total XP, streak and current language.
Can I get translation hints for vocabulary?
Yes! Use get_dictionary_hints with target and source language codes plus a list of words. It returns common translations for each word, useful for building flashcards or studying vocabulary.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
