Anki MCP Server

anki-mcp

MCP server for Anki. This server allows interaction with Anki through the Model Context Protocol (MCP). It enables users to manage flashcards, decks, and review processes programmatically.

Prerequisites

• Node.js and npm installed.
• AnkiConnect plugin installed and running in Anki.
• For audio features: Azure API key (set in .env file as AZURE_API_KEY) and Anki Media Directory (set as ANKI_MEDIA_DIR).

Setup and Execution

Highly recommended to run locally, since AnkiConnect only works locally.

Was only tested on windows.

To run locally:

1. Clone the repository:
   git clone https://github.com/nietus/anki-mcp
2. Install dependencies:
   npm install
3. Build the project
   npm run build
4. Setup for Audio Features (If you want to use audio tools):Create a .env file in the root directory with your Azure API key and Anki media directory:
   AZURE_API_KEY=your_azure_api_key_here ANKI_MEDIA_DIR=path/to/your/anki/media/directory
   For Anki media directory, use the path to your Anki collection.media folder. This is where audio files will be stored. If you have trouble, paste it directly into the code.
   • Windows example: C:\Users\username\AppData\Roaming\Anki2\User 1\collection.media
   • macOS example: /Users/username/Library/Application Support/Anki2/User 1/collection.media
   • Linux example: /home/username/.local/share/Anki2/User 1/collection.media

   Note: The ANKI_MEDIA_DIR is required for audio generation to work properly as Anki needs to find the audio files in its media collection.

5. Integrate with Cursor settings (for local execution):To run your local build of anki-mcp with Cursor, you need to tell Cursor how to start the server. Below are example configurations which you can access on cursor settings. Replace YOUR_USERNAME and adjust the path if you cloned anki-mcp to a different location than Downloads.Windows:
   "anki": { "command": "cmd", "args": [ "/c", "node", "c:/Users/YOUR_USERNAME/Downloads/anki-mcp/build/client.js" ] }
   macOS / Linux:
   "anki": { "command": "bash", "args": [ "-c", "node /Users/YOUR_USERNAME/Downloads/anki-mcp/build/client.js" ] }

Available Tools

To debug the tools, use

The server provides the following tools for interacting with Anki:

• update_cards:
  • Description: After the user answers cards you've quizzed them on, use this tool to mark them answered and update their ease.
  • Input: An array of answers, each with cardId (number) and ease (number, 1-4).
• add_card:
  • Description: Create a NEW flashcard in Anki. Use ONLY for creating new cards, NOT for updating existing ones (will throw an error if the card already exists). For updating existing cards, use update_note_fields with the noteId instead. Note content uses HTML.
    • Line breaks: <br>
    • Code: <pre style="background-color: transparent; padding: 10px; border-radius: 5px;">
    • Lists: <ol> and <li>
    • Bold: <strong>
    • Italic: <em>
  • Input:
    • fields: (object) An object where keys are field names (e.g., "Hanzi", "Pinyin") and values are their HTML content.
    • modelName: (string) The name of the Anki note type (model) to use.
    • deckName: (optional string) The name of the deck to add the card to. Defaults to the current deck or 'Default'.
    • tags: (optional array of strings) A list of tags to add to the note.
• add_card_with_audio:
  • Description: Create a NEW flashcard in Anki with automatically generated audio from Azure TTS. Use ONLY for creating new cards, NOT for updating existing ones (will throw an error if the card already exists). For updating audio on existing cards, use update_card_with_audio with the noteId instead.
  • Input:
    • fields, modelName, deckName, tags: Same as add_card.
    • sourceField: (string) Field name containing the text to generate audio from.
    • audioField: (string) Field name where the generated audio will be stored.
    • language: (optional string) Language code for TTS (e.g., 'en', 'es', 'fr'). Defaults to 'en'.
  • Supported languages: en, es, fr, de, it, ja, ko, pt, ru, zh, ar, nl, hi, tr, pl, sv, fi, da, no, cs, hu, el, he, th, vi, id, ms, ro.
• update_card_with_audio:
  • Description: Update an EXISTING card by generating audio from a specified field and adding it to an audio field. Use ONLY for cards that already exist (you must have the noteId). For creating new cards with audio, use add_card_with_audio instead.
  • Input:
    • noteId: (number) The ID of the Anki note to update.
    • sourceField: (string) Field name containing the text to generate audio from.
    • audioField: (string) Field name where the generated audio will be stored.

• get_due_cards:
  • Description: Returns a given number of cards due for review.
  • Input: num (number).
• get_new_cards:

  • Description: Find cards using a raw Anki search query. Returns detailed card information including fields.
  • Input: query (string, e.g., 'deck:Default -tag:test', or '"deck:My Deck" tag:important'). To filter for empty fields, use '-FieldName:_*' (e.g., '-Hanzi:_*').
• update_note_fields:
  • Description: Update specific fields of an EXISTING Anki note. Use ONLY when you already have the noteId of an existing card. For creating new cards, use add_card instead.
