How to Use the Duolingo MCP in Cursor

Q: How do I install the Duolingo MCP server in Cursor?

Add the configuration to your .cursor/mcp.json file in your project root. Cursor will automatically detect the tools and make them available to your agent.

Q: What is the difference between the two Duolingo user lookup tools?

The getuserbyusername tool queries profiles using standard display names, while getuserbyid uses numeric identifiers. Both return the same payload format.

Write language learning apps and track your Duolingo stats directly from the Cursor editor.

Query the Duolingo MCP Server in Agent Mode

The `get_user_by_username` tool pulls real-time profile statistics and skill progress into your active Cursor session. This allows the editor's Agent mode to write code using actual JSON structures instead of placeholder mock data. If you need to build lookup functions, `get_user_by_id` gets identical profile schemas via numeric IDs. Cursor reads this live payload to write accurate data parsers and UI components on your first try.

Build Flashcard Apps with Live Translations

The `get_dictionary_hints` tool translates specific word tokens across major language codes directly inside your editor. Your Cursor MCP client uses these live translation pairs to populate local database seeds and test suites. You can also run `get_version_info` to check supported API capabilities before writing your translation logic. This ensures your code handles language codes correctly without runtime exceptions.

Integrate Social Features and Leaderboards

The `get_friends` tool gets usernames, active streaks, and XP totals for any specified user ID. Cursor uses this live connection to help you write and test social widgets without manually copying test profiles. To build competitive features, `get_daily_leaderboard` and `get_leaderboard` pull current standings and weekly tiers. This lets your agent generate complete ranking tables and sorting algorithms using live production data.

Setup guide

Set up Duolingo MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Duolingo MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Duolingo transactions." If the MCP tools are loaded correctly, Cursor will call the Duolingo tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "duolingo-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }

Common questions about Duolingo MCP in Cursor

Add the configuration to your `.cursor/mcp.json` file in your project root. Cursor will automatically detect the tools and make them available to your agent.

No, the tools are strictly read-only for progress data. While `get_store_items` lists shop inventory, the server cannot execute purchases or modify your account state.

The token is only required if you want to pull detailed skill trees or private profile data. Public metrics like your current streak and total XP do not require any credentials.

The `get_user_by_username` tool queries profiles using standard display names, while `get_user_by_id` uses numeric identifiers. Both return the same payload format.

Your credentials reside strictly in your local environment variables or project config files. Cursor transmits these tokens directly to the API endpoints and never exposes your streak or XP data to external logging services.
