MindDory Brain

The official Model Context Protocol server for MindDory, an AI flashcard and vocabulary-learning app.

Connect MindDory to Claude (or any MCP-compatible client) and your AI becomes a language study partner: as you chat in a language you are learning, it captures the new words and phrases you meet into spaced-repetition flashcards, logs grammar mistakes for review, and can quiz you on whatever is due today — all scoped to your CEFR level and target language. Everything syncs with the MindDory apps (iOS, Android, and web at app.minddory.com).

It is transparent and opt-in: you connect MindDory yourself, and on its first reply the assistant tells you it is connected and will add new vocabulary as you chat. It never captures silently, and it answers honestly if you ask what it has saved.

Built on the proven SM-2 spaced-repetition algorithm. Free to connect; advanced spaced-repetition writes are part of MindDory Premium.

Troubleshooting

• No sign-in email / can't authorize. Connecting sends a one-time magic link to your MindDory account email. Check spam, and use the same email as your MindDory account. Links expire after a short window; reconnect to get a fresh one.
• "This tool requires an active MindDory Premium subscription" (HTTP 402). The write tools (capture_word, capture_grammar_mistake, mark_demonstrated, mark_struggled, log_interaction) require MindDory Premium. Read tools work on the free tier. Upgrade in the app or at https://app.minddory.com.
• Tools don't appear after connecting. MCP clients cache the tool list; disconnect and reconnect the connector to refresh it.
• Captured words aren't in the app. New words sync to the "Chat Discoveries" folder. Re-open or pull-to-refresh the app, and confirm you're signed into the same account.
• Wrong language captured. Capture is scoped to a language code; if a word lands under the wrong language, tell the assistant the correct language and it will recapture.
