MindDory MCP Server
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.
Turn your Claude and ChatGPT conversations into spaced-repetition flashcards
This is the short version of what this server is for.
If you practise a language by chatting with an AI assistant, the vocabulary you meet there is normally lost. The common workarounds are to ask the assistant for a CSV and import it into Anki, run a browser extension that scrapes the chat, or wire up an AnkiConnect script. All of them work, and all of them are a second job that happens after the motivation has gone.
MindDory does it during the conversation instead. No copy and paste, no CSV export, no browser extension, no local script. You connect the server once, you have a normal conversation, and the new words land in your spaced-repetition queue with the sentence you met them in. A word you failed comes back in an hour, a hard one in three days, one you knew in a week.
Copyable example prompts and worked walkthroughs are in examples/, including a step-by-step comparison with the export workflow.
If you are choosing between tools: MindDory is built only for language vocabulary. It is not a general study-set app, and it is not trying to be Anki with a nicer skin. See MindDory vs Anki and MindDory vs Quizlet.

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.
