Development
Install dependencies:
npm installBuild the server:
npm run buildFor development with auto-rebuild:
npm run watchMedia Files
How Media Files Are Handled
When you add cards with images or audio files, the server automatically handles different types of media sources:
-
Local File Paths: If you provide an absolute path to a file on your computer (e.g.,
/Users/mycomputer/Documents/images/prune.jpg), the server will:- Read the file from your disk
- Convert it to base64
- Upload it to Anki's media collection using the
storeMediaFileAPI - Reference it in the card by filename
-
URLs: If you provide a URL (e.g.,
https://example.com/image.jpg), Anki-Connect will download the file automatically when the card is created. -
Existing Media: If you provide just a filename (e.g.,
prune.jpg), it assumes the file already exists in Anki's media folder.
Troubleshooting Image Issues
If images don't show up properly in Anki:
- Check the file path: Make sure the path to your image file is correct and the file exists
- File permissions: Ensure the file is readable by the application
- Supported formats: Anki supports common image formats (JPG, PNG, GIF, SVG, WebP)
- File size: Very large files might cause issues
- Special characters: Avoid special characters in filenames when possible
The server will now automatically handle local file paths, so you don't need to manually copy images to Anki's media folder anymore.

Installation & Configuration
Installation
- Clone or download this repository
- Install dependencies:
npm install - Build the server:
npm run build
Configuration with Claude Desktop
Add the server configuration to your Claude Desktop config file:
MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%/Claude/claude_desktop_config.json
{
"mcpServers": {
"anki-mcp-server": {
"command": "/absolute/path/to/anki-mcp-server/build/index.js"
}
}
}๐ก Tip: Replace
/absolute/path/to/anki-mcp-serverwith the actual full path to where you cloned this repository.
Configuration with Other MCP Clients
This server follows the standard MCP protocol and can be used with any MCP-compatible client. Configure it as a stdio-based server pointing to build/index.js.
Verification
After configuration:
- Restart Claude Desktop (or your MCP client)
- Ensure Anki is running with AnkiConnect installed
- The server should appear in your available MCP servers
- Test with a simple query like "Show me 5 due cards from Anki"
Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:
npm run inspectorThe Inspector will provide a URL to access debugging tools in your browser where you can:
- Test tool calls interactively
- View request/response logs
- Debug connection issues
- Validate tool schemas
Troubleshooting
Server not appearing in Claude Desktop:
- Verify the path in config is absolute (not relative)
- Check that
build/index.jsexists (runnpm run build) - Restart Claude Desktop after config changes
"Connection refused" or timeout errors:
- Ensure Anki is running
- Verify AnkiConnect is installed (Tools โ Add-ons)
- Check AnkiConnect settings allow localhost connections (default)
Cards not updating/creating:
- Close the Anki browser if you have it open (known AnkiConnect limitation)
- Verify the deck and note type names match exactly (case-sensitive)
- Check field names match your note type's field configuration
