FAQ

Frequently asked questions

01

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.

02

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.

03

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.

04

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.

05

How does Windsurf discover MCP tools?

Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.

06

Can Cascade chain multiple MCP tool calls?

Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.

Does Windsurf support multiple MCP servers?
