📋 Prerequisites

1. Install Anki

Download and install Anki if you haven't already.

2. Install AnkiConnect Plugin

Open Anki
Go to Tools → Add-ons
Click Get Add-ons...
Enter code: 2055492159
Restart Anki

📋 Version Requirements: This server requires AnkiConnect version 25.2.25.0 or newer (released 2025-02-25) for full compatibility. Most features work with older versions, but we recommend updating for the best experience.

3. Configure AnkiConnect (Optional)

AnkiConnect works out of the box, but you can customize settings:

Go to Tools → Add-ons
Select AnkiConnect and click Config
Default settings should work fine for most users

🚀 Quick Start

Option 1: Use with Claude Desktop (Recommended)

Install the package

   npm install -g @arielbk/anki-mcp

Configure Claude Desktop

Edit your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

Add this configuration:

   {
     "mcpServers": {
       "anki": {
         "command": "anki-mcp",
         "args": []
       }
     }
   }

Restart Claude Desktop

Start using it!

Make sure Anki is running with AnkiConnect enabled
Ask Claude: _"Show me my Anki decks"_ or _"Quiz me with 5 cards"_

💡 Pro Tip: You can test your setup by asking Claude simple questions like _"How many Anki decks do I have?"_ or _"What's in my largest deck?"_

Option 2: Development Setup

Clone the repository

   git clone https://github.com/arielbk/anki-mcp.git
   cd anki-mcp

Install dependencies

   pnpm install

Build the project

   pnpm build

Test the server

   # Use the MCP inspector to test functionality
   pnpm inspect

Option 3: Use with Other MCP Clients

This server works with any MCP-compatible client. You can also use it with:

MCP Inspector: Interactive debugging tool
Cline: VS Code extension for AI coding
Custom MCP clients: Build your own using the MCP SDK

For stdio transport, run:

node dist/index.js

For localhost HTTP (Streamable HTTP) transport, run:

node dist/index.js --http --host=127.0.0.1 --port=3000
# The MCP endpoint will be at http://127.0.0.1:3000/mcp

Clients that support Streamable HTTP can connect directly. Legacy SSE clients may still work via client-side fallback.

🎮 Usage Examples

Once configured with Claude Desktop, you can have natural conversations like:

📖 Study Sessions

You: "I have a Japanese exam tomorrow. Can you quiz me on Hiragana cards I haven't reviewed in a week?"

Claude: I'll find your Hiragana cards that need review and start a quiz session...

📝 Content Creation

You: "Create flashcards for the major battles of World War II with dates and significance"

Claude: I'll create comprehensive flashcards covering the key WWII battles...

📊 Study Analytics

You: "How am I doing with my medical terminology deck? Show me my weak areas."

Claude: Let me analyze your performance on the medical terminology deck...

🏷️ Organization

You: "Tag all cards about cardiovascular system with 'cardiology' and move them to my MCAT prep deck"

Claude: I'll help you organize those cards...

🔧 Available Tools

The server provides 7 intuitive tools that cover everything you need:

📝 Manage Flashcards

Create, update, delete, and search your flashcards. Perfect for content creation, bulk updates, and organization.

🎯 Study Sessions

Run interactive quiz sessions, manage card scheduling, and track which cards need review.

📚 Manage Decks

Create and organize decks, move cards around, and configure deck settings.

📊 Get Analytics

Dive into your study statistics, review history, and learning patterns.

🎨 Manage Models

Customize note types, add fields, modify templates, and style your cards.

🔧 Anki Operations

Handle sync, media files, imports/exports, and other utility operations.

🖼️ Get Media File

Retrieve media files (images, audio, etc.) from your Anki collection. AI assistants can analyze images directly (though they won't display in the UI).

💡 Pro Tip: Many operations support pagination to prevent overwhelming your context window. Use limit and offset parameters when working with large result sets.

🛠 Development

# Run in development mode with auto-reloading
pnpm dev

# Lint the code
pnpm lint

# Format the code
pnpm format

# Test with MCP inspector
pnpm inspect

🔧 Configuration

AnkiConnect Settings

The server connects to AnkiConnect on localhost:8765 by default. If you've customized your AnkiConnect configuration, you may need to adjust the connection settings.

Important: Make sure Anki is running and AnkiConnect is installed before using the MCP server. The server will fail to connect if AnkiConnect is not accessible.

💡 Note: The underlying yanki-connect library supports auto-launching Anki on macOS, but this feature is not currently exposed in the MCP server configuration. You'll need to start Anki manually.

Claude Desktop Advanced Configuration

For advanced users, you can pass additional parameters:

{
  "mcpServers": {
    "anki": {
      "command": "anki-mcp",
      "args": ["--verbose"],
      "env": {
        "ANKI_CONNECT_HOST": "localhost",
        "ANKI_CONNECT_PORT": "8765"
      }
    }
  }
}

Troubleshooting

Common Issues:

"Failed to connect to AnkiConnect": Ensure Anki is running and AnkiConnect plugin is installed
"No decks found": Make sure you have at least one deck in Anki
Claude doesn't respond: Restart Claude Desktop after configuration changes
Permission errors: Check that the global npm install worked correctly with npm list -g @arielbk/anki-mcp
