A Model Context Protocol (MCP) server that provides tools for managing Anki flashcards through AnkiConnect. This server allows AI assistants to create, search, and manage Anki cards and decks programmatically.

• Card Management: Create new flashcards with front/back content
• Deck Operations: List, create, and manage Anki decks
• Search Functionality: Search cards using Anki's powerful search syntax
• Media Support: Add images and audio files to cards
• Model Support: Work with different note types/models
• Sync Integration: Trigger AnkiWeb synchronization
• Configurable: Customizable AnkiConnect URL

1. Anki Desktop: Install Anki desktop application
2. AnkiConnect: Install the AnkiConnect addon in Anki
3. Go: Go 1.21 or later for building from source

git clone https://github.com/ezynda3/anki-mcp.git
cd anki-mcp
go build -o anki-mcp .

go install github.com/ezynda3/anki-mcp@latest

The server can be configured using environment variables:

• ANKI_CONNECT_URL: AnkiConnect server URL (default: http://localhost:8765)

Add the following to your Claude Desktop configuration file:

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

{
  "mcpServers": {
    "anki": {
      "command": "/path/to/anki-mcp",
      "env": {
        "ANKI_CONNECT_URL": "http://localhost:8765"
