Manage Anki Flashcards Programmatically

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.

Running locally via npx

If you only wish to use the tool and not develop the tool,
you may launch an MCP STDIO server locally using npx:

npx -y github:nietus/anki-mcp

This can be used in Desktop MCP clients such as Msty Studio or others.

Running locally via source code

Alternatively, you can run locally via source code using these instructions:

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"
       ]
   }
   

6. Integrate with Claude Desktop using an .mcpb bundle:

   The recommended way to use this server with Claude Desktop is to install it as an MCP extension bundle (.mcpb file).

   1. Build and package the extension:

      npm install
      npm run build
      npm run pack:mcpb
      

      This will produce a file at dist/anki-mcp.mcpb.

   2. Install the bundle in Claude Desktop:

      • Open Claude Desktop.
      • Go to Settings → Extensions.
      • Drag and drop the dist/anki-mcp.mcpb file into the Extensions panel.

      Claude will handle launching the server automatically when needed.

   3. Configure environment variables:

      When prompted during installation, provide your AZURE_API_KEY and ANKI_MEDIA_DIR (the path to your Anki collection.media folder). These are required for audio features and media file handling.

   That’s it! No manual configuration is needed-Claude Desktop will manage the server for you once the .mcpb bundle is installed.
   macOS / Linux:

 "anki": {
       "command": "bash",
       "args": [
         "-c",
         "node /Users/YOUR_USERNAME/Downloads/anki-mcp/build/client.js"
       ]
     }

Create a Claude Desktop extension bundle (.mcpb)

If you want one-click installation inside Claude Desktop, you can package this server as an MCP bundle:

1. Install dependencies and build the project:

   npm install
   npm run build
   

2. Generate the .mcpb bundle (requires the @anthropic-ai/mcpb CLI, which expects Node.js 18+):

   npm run pack:mcpb
   

The script stages the compiled server (build/), copies runtime dependencies, and produces dist/anki-mcp.mcpb. Drag that file into Claude Desktop's Settings → Extensions panel to install. When prompted, provide the Azure Speech API key and Anki media directory so audio tools can save files in your collection.media folder.

Available Tools

To debug the tools, use

npm run inspector

The server provides the following tools for interacting with Anki:

• update_cards:
