Memora

Turn any conversation into an interactive study session, right inside Claude Desktop. Ask Claude to make a deck and it generates the cards, then renders them as an inline review you can click through: flipflashcards, answermultiple-choice quizzes, and fill inclozeblanks. Every answer updates aspaced-repetitionschedule, and your results flow back to Claude so it can drill what you missed.

Keywords: Model Context Protocol, MCP server, MCP Apps, Claude Desktop, flashcards, quizzes, spaced repetition, SRS, FSRS, Anki alternative.

Built on theMCP Apps extension(SEP-1865): core MCP spec2025-11-25plus the Apps extension2026-01-26.

- Flashcards: click to flip, then gradeGot it/Missed it.
- Multiple-choice quizzes: pick an option and the correct/wrong answers reveal instantly.
- Cloze (fill-in-the-blank): the blank reveals in place so the sentence stays intact. Write a blank as[...]in a card front and it becomes a cloze card automatically.

Spaced repetition: every grade updates a per-cardFSRSschedule (viats-fsrs), so weak cards resurface sooner and due cards come first. Ask"what's due today?"for a summary across all your decks.

{ "mcpServers": { "memora": { "command": "npx", "args": ["-y", "@servation/memora-mcp", "--stdio"] } } }

Then fully quit Claude Desktop (from the system tray) and relaunch.memoraappears under Settings > Developer, pre-loaded with a few sample decks.

Your decks are stored in~/.memora/decks.json(override the path with theMEMORA_DECKSenvironment variable). Hand-edit that file or let Claude manage it.

git clone https://github.com/Servation/memora-mcp.git cd memora-mcp npm install npm run build

Point the config at the built entry with an absolute path (decks then live in the repo'sdata/decks.json):

{ "mcpServers": { "memora": { "command": "node", "args": ["C:\\path\\to\\memora-mcp\\dist\\main.js", "--stdio"] } } }

- review my World Capitals deck
- make me a deck of 10 Spanish travel phrases

- Server: TypeScript,@modelcontextprotocol/sdkplus@modelcontextprotocol/ext-apps, stdio transport (Streamable HTTP also available).
- UI: React plus Vite, bundled to a single inlined HTML file viavite-plugin-singlefile.
- Scheduling:ts-fsrs(FSRS).
- Runtime is plainnodeonce built (no bun or tsx needed).

{ "Deck Name": [ { "front": "Capital of France?", "back": "Paris" } ] }

- Stored in~/.memora/decks.jsonwhen installed (ordata/decks.jsonfrom source); override withMEMORA_DECKS.
- Read live (mtime-cached).create_deck,create_quiz, andgrade_cardwrite here atomically.
- Aquizcard adds"options": ["...", "..."]; itsbackis the correct option.
- Aclozecard writes the blank as[...]in the front, with the hidden term as theback.
- Cards gain aduedate and an FSRSsrsblock as you review them; cards without them are treated as new.
- Keep it valid JSON, or the server falls back to a built-in default deck.

For fast local iteration you can also run the app against the MCP Apps reference host (basic-host) from theext-apps repo.

SeeTODO.mdfor the backlog: npm + MCP Registry publishing, cross-client hosting (Streamable HTTP), tests around parsing and scheduling, and a real screen-capture demo GIF.
