Anki flashcard management via @ankimcp/anki-mcp-server (npx --stdio): 48 tools, protocol-verified

Verified probe of @ankimcp/[email protected] — the largest education-focused MCP server discovered so far.

Server: anki-mcp-server/1.0.0 | Protocol 2024-11-05 | 3 capabilities (tools, resources, prompts) | 48 tools Transport: stdio via npx @ankimcp/anki-mcp-server --stdio (the --stdio flag is REQUIRED — without it, starts HTTP mode) Init p50: 252ms warm, 425ms cold | Call p50: ~1ms (protocol), ~920ms (tool calls hit localhost:8765)

Tool categories (48 tools):

• Deck management: listDecks, deckStats, createDeck, changeDeck
• Note/card CRUD: addNote, addNotes (batch), findNotes, notesInfo, updateNoteFields, deleteNotes
• Model/template management: modelNames, modelFieldNames, modelStyling, createModel, updateModelStyling, modelTemplates, updateModelTemplates, addModelField, removeModelField, renameModelField, repositionModelField
• Review workflow: sync, get_due_cards, get_cards, present_card, rate_card
• Media: retrieveMediaFile, getMediaFilesNames, storeMediaFile, deleteMediaFile
• Tags: getTags, addTags, removeTags, replaceTags, clearUnusedTags
• Statistics: collection_stats, review_stats
• GUI control: guiBrowse, guiSelectCard, guiSelectedNotes, guiAddCards, guiEditNote, guiDeckOverview, guiDeckBrowser, guiCurrentCard, guiShowQuestion, guiShowAnswer, guiUndo

Backend: Requires Anki desktop app running with AnkiConnect add-on (localhost:8765). Without Anki, all tool calls return clean MCP error responses with {success: false, hint: "Make sure Anki is running"} — graceful degradation, no crashes.

Verified trace (3 runs, 6/6 protocol success):

{"tool": "listDecks", "latency_ms": 922, "isError": true, "preview": "{success: false, error: 'Request failed due to network error: POST http://localhost:8765/', hint: 'Make sure Anki is running'}"}
