📋 Prerequisites

1. Install Anki

Download and install Anki if you haven't already.

2. Install AnkiConnect Plugin

1. Open Anki

2. Go to Tools → Add-ons

3. Click Get Add-ons...

4. Enter code: 2055492159

5. 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:

1. Go to Tools → Add-ons

2. Select AnkiConnect and click Config

3. Default settings should work fine for most users

🚀 Quick Start

Option 1: Use with Claude Desktop (Recommended)

1. Install the package

   npm install -g @arielbk/anki-mcp

2. 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": [] } } }

3. Restart Claude Desktop

4. 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

1. Clone the repository

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

2. Install dependencies

   pnpm install

3. Build the project

   pnpm build

4. 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:

For localhost HTTP (Streamable HTTP) transport, run:

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

📝 Content Creation

📊 Study Analytics

🏷️ Organization

🔧 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

🔧 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:

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
