Built-in capabilities (8)
Shows top users by XP for the current day. Optionally specify language code and timezone. Get daily leaderboard for a language
Returns translation pairs for the given tokens. Useful for building flashcards or vocabulary tools. Target and source are language codes (e.g. "es", "fr", "de", "en"). Get dictionary hints for word translations
Optionally provide a user ID. Returns friend usernames, IDs, streaks and XP totals. Get Duolingo friends list
Optionally provide a user ID to get leaderboard info for a specific user. Returns rankings with usernames, XP totals and positions. Get Duolingo leaderboard data
Requires authentication for full details. Returns item IDs, names, prices and descriptions. Get Duolingo store items
Returns the same data as get_user_by_username but uses the numeric ID instead. Get a Duolingo user profile by user ID
Returns username, user ID, avatar, current language, total XP, streak, skills and progress. Note: Full profile data (detailed progress, skill trees) requires authentication and only works for your own account. Get a Duolingo user profile by username
Useful for understanding available language codes and API capabilities. Get Duolingo API version information
Why CrewAI?
When paired with CrewAI, Duolingo becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Duolingo tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

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 does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
