From the repository
1. Make sure Anki is running with AnkiConnect installed
2. Run the MCP server:
npm start
For testing, a separate configuration file .env.test is provided:
cp .env.example .env.test
Edit .env.test to set test-specific values:
ANKI_CONNECT_URL=http://localhost:8765
ANKI_CONNECT_VERSION=6
ANKI_MOCK_MODE=true
To run in test mode:
npm run start:test
To use this MCP server with Claude Desktop:
1. Open Claude Desktop
2. Edit the Claude Desktop configuration file located at:
- macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
- Windows: %APPDATA%\Claude\claude_desktop_config.json
- Linux: ~/.config/Claude/claude_desktop_config.json
3. Add the following configuration to the mcpServers section:
{
"mcpServers": {
"anki": {
"command": "node",
"args": ["path/to/anki-mcp-server/dist/index.js"]
}
}
}
Replace "path/to/anki-mcp-server" with the actual path to where you cloned this repository.
Once configured, you can use the following tools in Claude:
Could you analyze my Anki leech cards and suggest ways to improve my study?
Claude will use the MCP server to retrieve your leech cards and analyze them.
get_leech_cards
Retrieves cards tagged as leeches from Anki. Parameters: detailed (optional, boolean, default: true), count (optional, number): Number of random cards to return (defaults to all cards)
tag_reviewed_cards
Adds a date-stamped 'reviewed' tag to specified cards. Parameters: card_ids (required, array of numbers): Array of card IDs to tag as reviewed, custom_tag_prefix (optional, string, default: '見直し'): Custom prefix for the tag

Connects to Anki via AnkiConnect to retrieve leech-tagged flashcards for use in Claude Desktop.
An MCP (Model Context Protocol) server for Claude Desktop that connects to Anki via AnkiConnect and retrieves leech-tagged cards.
- Connects to Anki via AnkiConnect API
- Retrieves cards with "leech" tags
- Adds date-stamped review tags to cards
- Provides comprehensive card data for analysis by Claude
- Can be used with Claude Desktop
- Ankiinstalled and running
- AnkiConnectadd-on installed in Anki
- Node.js and npm
git clone https://github.com/yourusername/anki-mcp-server.git cd anki-mcp-server
The server can be configured using environment variables. Copy the provided example file to create your own configuration:
Then edit the.envfile to customize your settings:
If the environment variables are not set, the server will use the default values.
Finding Your Local IP Address for AnkiConnect
If connecting tolocalhostdoesn't work, you'll need to use your computer's local IP address instead. Configure your.envfile with:
ANKI_CONNECT_URL=http://YOUR_LOCAL_IP:8765
- macOS: Open Terminal and runifconfigoripconfig getifaddr en0(for WiFi)
- Windows: Open Command Prompt and runipconfig
- Linux: Open Terminal and runip addr showorhostname -I
Look for IPv4 addresses like192.168.x.xor10.x.x.xin the output.
For testing, a separate configuration file.env.testis provided:
Edit.env.testto set test-specific values:
ANKI_CONNECT_URL=http://localhost:8765 ANKI_CONNECT_VERSION=6 ANKI_MOCK_MODE=true
- Make sure Anki is running with AnkiConnect installed
- Run the MCP server:
npm start
To use this MCP server with Claude Desktop:
Edit the Claude Desktop configuration file located at:
- macOS:~/Library/Application Support/Claude/claude_desktop_config.json
- Windows:%APPDATA%\Claude\claude_desktop_config.json
- Linux:~/.config/Claude/claude_desktop_config.json
Add the following configuration to themcpServerssection:
{ "mcpServers": { "anki": { "command": "node", "args": ["path/to/anki-mcp-server/dist/index.js"] } } }
Replace"path/to/anki-mcp-server"with the actual path to where you cloned this repository.
Once configured, you can use the following tools in Claude:
Could you analyze my Anki leech cards and suggest ways to improve my study?
Claude will use the MCP server to retrieve your leech cards and analyze them.
Retrieves cards tagged as leeches from Anki.
- detailed(optional, boolean, default: true): Whether to return comprehensive card data or just IDs
- count(optional, number): Number of random cards to return (defaults to all cards)
Adds a date-stamped "reviewed" tag to specified cards. This allows you to track which cards you've reviewed with Claude.
- card_ids(required, array of numbers): Array of card IDs to tag as reviewed
- custom_tag_prefix(optional, string, default: "見直し"): Custom prefix for the tag
The tag will be in the format見直し::YYYYMMDD(or your custom prefix if specified).
I've reviewed these cards, please tag them as reviewed: [1234567890, 1234567891]
- "Could not connect to Anki"- Make sure Anki is running and AnkiConnect is properly installed
- "No leech cards found"- You don't have any cards tagged as "leech" in Anki
- Connection issues with localhost- If you're unable to connect usinglocalhost:
- Find your local IP address as described in the Configuration section
- Update your.envfile to useANKI_CONNECT_URL=http://YOUR_LOCAL_IP:8765
- Make sure AnkiConnect is configured to allow connections from your IP address
- Restart the MCP server after making these changes
For testing without affecting actual Anki data, you can use the mock mode:
- SetANKI_MOCK_MODE=truein your.envfile or use the provided.env.testfile
- Run the server withnpm run start:test
In mock mode, the server will simulate all Anki operations without actually connecting to Anki. This is useful for testing Claude integrations without risking data changes.
