Anki Connect MCP Server

A Model Context Protocol (MCP) server that provides seamless integration with Anki through the AnkiConnect add-on. This server enables AI assistants and other MCP clients to interact with your Anki flashcard collection programmatically.

What is Anki Connect?

AnkiConnect is a powerful Anki add-on that exposes Anki's functionality through a REST API. It allows external applications to:

• Create, modify, and delete flashcards
• Manage decks and their configurations
• Control Anki's GUI programmatically
• Search and retrieve card information
• Manage tags and note types
• Perform bulk operations on cards and notes

What is MCP (Model Context Protocol)?

The Model Context Protocol is a standardized way for AI assistants to connect to external data sources and tools. This MCP server acts as a bridge between MCP clients (like Claude Desktop) and AnkiConnect, allowing AI assistants to help you manage your Anki flashcards naturally through conversation.

Features

This MCP server provides comprehensive access to AnkiConnect functionality through the following tools:

Flashcard Management

• create_flashcard() - Create new flashcards with front and back content
• add_note() - Add notes with custom fields and tags
• add_notes() - Bulk add multiple notes
• update_note_fields() - Update existing note fields

MCP Client Configuration

Claude Desktop

To use this MCP server with Claude Desktop, add the following configuration to your MCP settings file:

Location of MCP configuration file:

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

Configuration Options:

Option 1: Using Node.js (Local Installation)

{
  "mcpServers": {
    "anki-connect-mcp": {
      "command": "node",
      "args": [
        "dist/index.js"
      ],
      "env": {},
      "disabled": false,
      "alwaysAllow": [
        "deck_names",
        "cards_info",
        "deck_names_and_ids",
        "gui_deck_browser"
      ]
    }
  }
}

Option 2: Using npx (NPM Package)

Then configure your MCP client:

{
  "mcpServers": {
    "anki-connect": {
      "command": "npx",
      "args": [
        "@spacholski1225/anki-connect-mcp"
      ],
      "env": {},
      "disabled": false,
      "alwaysAllow": [
        "deck_names",
        "cards_info",
        "deck_names_and_ids",
        "gui_deck_browser"
      ]
    }
  }
}

Option 3: Using Docker

{
  "mcpServers": {
    "anki-connect": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--network=host",
        "-e", "ANKI_CONNECT_URL=http://host.docker.internal:8765",
        "spacholski/anki-connect-mcp:latest"
      ],
      "env": {},
      "disabled": false,
      "alwaysAllow": [
        "deck_names",
        "cards_info",
        "deck_names_and_ids",
        "gui_deck_browser"
      ]
    }
  }
}

Docker-Specific AnkiConnect Configuration:

When using the Docker option, you must configure AnkiConnect with specific settings to allow Docker container access:

1. Go to Tools → Add-ons in Anki
2. Select AnkiConnect and click Config
3. Update the configuration with the following settings:

{
    "apiKey": null,
    "apiLogPath": null,
    "ignoreOriginList": [],
    "webBindAddress": "0.0.0.0",
    "webBindPort": 8765,
    "webCorsOriginList": [
        "http://localhost",
        "http://host.docker.internal",
        "http://host.docker.internal:3000"
    ]
}

Key Docker Configuration Points:

• webBindAddress: "0.0.0.0" - Allows AnkiConnect to accept connections from any IP address (required for Docker containers)
• webCorsOriginList - Must include "http://host.docker.internal" and related origins to allow cross-origin requests from Docker containers
• Restart Anki after making these configuration changes

Important Notes:

• For Node.js option: Replace the path in args with the actual path to your built index.js file
• For npx option: Uses the published NPM package @spacholski1225/anki-connect-mcp - no local installation required
• For Docker option: Uses the pre-built Docker image spacholski/anki-connect-mcp:latest
• The alwaysAllow array contains tools that won't require confirmation each time
• Make sure Anki is running with AnkiConnect enabled before using the MCP server
• For Docker option, the --network=host flag allows the container to access AnkiConnect on the host machine

Usage Examples

Once configured with an MCP client like Claude Desktop, you can interact with your Anki collection naturally:

• "Create a flashcard about the capital of France"
• "Show me all my deck names"
• "Find all cards tagged with 'vocabulary'"
• "Suspend all cards in the 'Difficult Words' deck"
• "Open the deck browser in Anki"

Troubleshooting

Common Issues

1. Connection refused: Make sure Anki is running and AnkiConnect is installed
2. Port conflicts: Check if port 8765 is available or configure AnkiConnect to use a different port
3. Permission errors: Ensure the MCP server has proper file system permissions
4. Tool not found: Verify the MCP client configuration and restart the client
