inoh-mcp

The remote MCP server for Inoh — the vocabulary app for the articulate. Connect it to Claude, ChatGPT, Cursor or any MCP-capable client and your AI can look words up in the Inoh dictionary and build flashcards for you, in your own account, while you are talking to it.

Ask for a word you just met in an article and it becomes a card with a definition, an example sentence, audio, an image and quiz options, ready to review in the Inoh app on your phone.

Connecting

You need a free Inoh account. Sign-in happens in your browser through Inoh's normal email flow, so your AI client never sees your password, and you can revoke access at any time from your Inoh account settings.

Step-by-step instructions for Claude, Cursor, ChatGPT, Gemini, VS Code and more are at docs.inoh.app. The address and troubleshooting are also in docs/installation.md.

Things people actually say:

• "Add serendipity to my Inoh deck."
• "I keep seeing runway in startup writing. Make me a card for that meaning, not the airport one."
• "Make cards for every word I got wrong in that article."
• "Is my platitudinous card ready yet?"
• "Do I already have serendipity in my deck?"
• "Give me ten random words from my deck."
• "What have I added to my deck lately?"
• "What should I review today?"
• "Quiz me on today's words."
• "Which words do I keep forgetting?"
• "Have I got any get phrasal verbs in my deck?"
• "Take banyan out of my deck, I know it now."
• "My moat card explains the wrong thing - redo it for the business sense."
• "That picture on my runway card is useless. Make the card again."
• "Delete the moat card I made earlier."
• "Put the banyan card back in my deck."
• "Inoh hasn't got enshittification. Can you get it added for everyone?"
• "Did that word I suggested ever make it into the dictionary?"

Ask for a word and the AI looks it up first, adding the public dictionary's card when Inoh already has one and generating a fresh one only when it does not.

search_deck looks through the words you hold rather than the ones you could add, so it answers "do I have this already?" without the dictionary's 45,000 entries drowning your own cards out. It forgives a typo the same way the app's search does, and it tells you which deck a word is in.

browse_deck is the one to reach for when there is no word to search for. Ask for a random handful and you get a different draw every time; ask for the newest or the oldest and you get them in the order you added them; ask what is due and you get today's review session, the same one the app would deal: the words due by the end of your day, most overdue first, then a few you have never reviewed; ask what you keep forgetting and you get the cards you have missed in review, the worst first. Reading your deck this way never touches a card's review schedule.

Reviewing in a conversation

Ask the AI to quiz you and it works through today's session however suits the conversation: it might say a word and ask what it means, give you a meaning and ask for the word, or use it in a sentence. After each answer it judges how well you remembered it (you had it, you half had it, or you didn't) and record_review saves that straight away, so stopping halfway loses nothing.

A review here counts exactly like one in the app. The word is scheduled by the same rules and won't come back until it is due again. Each review counts toward your streak: a day counts once you have reviewed 15 words, across the app and every AI client together, or once you have finished the day's session, with nothing already due left and five new words (or all you have) done.

A session is up to 15 words: the ten most overdue, then five new ones. When more are due than one session holds, the AI says so and can start another once you finish.

Your weekly allowance

Your plan includes a weekly allowance of MCP tool calls. A tool call is one thing your AI assistant does in Inoh for you: taking today's session, recording one answer, adding or looking up a word. Recording each answer is one call and taking the session is one more, so a full session of 15 words uses 16. Checking which account you're signed in as is free. The allowance resets on Monday at midnight where you are.

Plan	Tool calls a week	About
Free	50	3 review sessions a week (~6 reviews a day)
Plus	150	a review session every day (~20 a day)
Pro	500	several review sessions a day (~70 a day)

Adding, searching and browsing use tool calls too. When only a few are left the AI mentions it, and once they're gone it tells you when they come back and where to upgrade.

Removing versus deleting

These are different things, and the tools keep them apart.

Removing a card from your deck ends your review of it and nothing more. A public dictionary card stays in Inoh for everyone; a card you made stays in your own private dictionary. Either way you can add it back whenever you like, though you start its review progress over. This is what remove_card_from_deck does, for both kinds of card.

Deleting applies only to cards you made, and it is permanent: the card leaves your private dictionary, and its image and audio are destroyed with it. There is no undo. Asking for the word again later makes a brand new card, spending another of your monthly allowance, so the AI will check with you before deleting anything. If the card is simply wrong rather than unwanted, update_private_card remakes it in place and keeps your review progress.

Cards you create

A card you make here is yours alone. It goes into your private dictionary, which only you can see: it never joins the public Inoh dictionary, and never shows up in anyone else's feed or search. Two people asking for the same word each get their own.

It is a complete card rather than a stub: definition, example sentence, three audio clips, an image, phonetic transcription and both sets of quiz options. That means you can review it in the app the moment it appears, alongside the public dictionary's cards — and it shows up in the app's Dictionary tab under Private, badged as yours. Making one takes about 20 seconds.

Tell the AI which sense you mean when a word has several. "Runway" as months of cash is a different card from "runway" at an airport, and nothing reviews the result before it reaches you.

If Inoh already has the word — or you made a card for it before — generating stops before it starts and points you at that card. A public dictionary card is written and checked by Inoh, and adding one costs nothing against your monthly allowance, so it is the better choice nearly always. When you really do want your own card for a sense the existing one does not cover, say so and the AI can go ahead anyway.

How many you can make, per calendar month:

Plan	Cards per month
Free	50
Plus	300
Pro	1,000

When a card comes out wrong

Ask for it again rather than deleting it. update_private_card regenerates the definition, example sentence, image, audio and quiz options and writes them over the same card, so the card keeps its place in your deck and everything Inoh knows about how well you remember it. Deleting and remaking would throw that away and start the word over.

Say which sense you meant and it teaches that instead. Say nothing and it simply has another go at the sense it already had, which is what you want when the meaning was right but the sentence was flat or the picture unhelpful.

A redo costs one card from your monthly allowance, because it generates a new image - the expensive part of a card. It cannot change which word the card teaches: that is a different card, so delete this one and make that one.

Deleting

Deleting a card removes it completely: the card, its place in your deck, and its image and audio files. It does not give back the monthly allowance it used. Removing one of your own cards from a deck inside the Inoh app also deletes it, a few minutes later, once the undo window has passed.

Contributing to the public dictionary

Everything above is about your own cards. The public dictionary — the 45,000 entries every Inoh user shares — is the other half, and you can add to it. Say the dictionary ought to have a word and the AI sends it in for you, with the sense you described.

What happens then is different from making your own card in one important way: a person at Inoh reads it before anything is published. Inoh builds the card as usual, then it waits for a reviewer, so this takes days rather than a minute, and it can be turned down. If it is published, the card belongs to everyone who uses Inoh — and it is added to your deck too, so you are not waiting on your own suggestion to study the word.

Suggestions spend none of your monthly private-card allowance, so suggesting a word never uses up a card you might want for yourself. (One ceiling does apply: 100 requests a day across everything you ask Inoh to make, which exists to stop a runaway script rather than you.)

Which one to ask for:

You want	Ask for	You get it
The word in your deck today	A card of your own	In about a minute, guaranteed
The word in Inoh for everyone	A request	In a few days, if it is agreed

Nothing stops you doing both — make yourself a card now, and suggest the word as well. If the dictionary already has the word there is nothing to contribute, and the AI will offer you the existing card instead; say you mean a different sense and it can send the request anyway.

Ask "where did my suggestion get to?" and check_card_status answers for both kinds at once: your own cards read as ready, a suggestion reads as with a reviewer, published, or declined. The app's My Requests screen shows the same list.

Privacy and data handling

• The server stores nothing of its own. It acts on your Inoh account using your access token, and everything it reads or writes is scoped to you by the database's row level security.
• It holds no administrator credentials. There is no service-role key here, so a bug in a tool cannot reach past your own data.
• It logs no card content, no request bodies and no tokens. The only things written to the log are the startup line, rejected origins, and unexpected errors.
• Creating a card sends the word and the sense you described to Inoh's card pipeline, which uses OpenAI for the text, Google Cloud for the speech, and Google Gemini for the image. Nothing else about you is sent.
• A word you suggest for the public dictionary is read by a person at Inoh, along with the sense you wrote, because that is what reviewing it means. The published entry carries no trace of who asked for it.
• Your cards stay yours. Deleting a card deletes the underlying media too, unless another card legitimately shares the same file.
• You can revoke access at any time from your Inoh account, and nothing here survives it.

Security

Requests are authenticated with OAuth 2.1 bearer tokens; an unauthenticated request gets a 401 pointing at the server's protected-resource metadata, which is how MCP clients discover the sign-in flow. The /mcp endpoint also validates the Origin header, so a web page cannot drive the server from your browser.
