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
