@lifeng688/anki-mcp

MCP stdio server for controlling local Anki via AnkiConnect. Enables LLMs (Claude, Cursor, Cline) to manage Anki decks and notes through a standardized tool interface.

v0.1.0 — Initial MVP release. Safety-first, read-heavy toolset with dryRun support for writes.

Quick Install

npm install @lifeng688/anki-mcp

Or try it instantly:

npx @lifeng688/anki-mcp

Related MCP server: Anki MCP Server

Prerequisites

1. Anki desktop installed

2. AnkiConnect add-on (code 2055492159) — install via Tools → Add-ons → Get Add-ons

3. Node.js >= 18.0.0

Verify AnkiConnect is running:

curl -X POST http://127.0.0.1:8765 \
  -H "Content-Type: application/json" \
  -d '{"action":"version","version":6}'
# Expected: {"result":6,"error":null}

Core Features

• Deck management — List and create decks (including hierarchical :: decks)

• Note operations — Add, search, update, and inspect notes

• Batch operations — Add multiple notes with per-item result tracking

• Safety first — dryRun support for batch writes, duplicate prevention, field validation

• Unified responses — Consistent success/error envelope across all tools

• Security-focused — Localhost only, no DB access, no card content logging

MCP Client Configuration

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "anki": {
      "command": "node",
      "args": ["$(npm root)/@lifeng688/anki-mcp/dist/index.js"]
    }
  }
}

With environment variables:

{
  "mcpServers": {
    "anki": {
      "command": "node",
      "args": ["$(npm root)/@lifeng688/anki-mcp/dist/index.js"],
      "env": {
        "ANKI_CONNECT_URL": "http://127.0.0.1:8765",
        "ANKI_CONNECT_VERSION": "6",
        "ANKI_DEFAULT_DECK": "Default::MCP",
        "ANKI_DEFAULT_MODEL": "Basic",
        "ANKI_LOG_LEVEL": "warn"
      }
    }
  }
}

Note: Replace $(npm root)/@lifeng688/anki-mcp/dist/index.js with the actual resolved path. You can find it with:

npm root -g
# or
npm root

Cursor / Cline

Same JSON format — add to your MCP server configuration. Point args to the installed dist/index.js inside the @lifeng688/anki-mcp package directory.

Global Install

npm install -g @lifeng688/anki-mcp

Then configure your client to point to:

<global-npm-root>/@lifeng688/anki-mcp/dist/index.js

Environment Variables

URL Resolution Priority:

1. ANKI_CONNECT_URL — if set, used as-is (must point to localhost)

2. ANKI_CONNECT_HOST + ANKI_CONNECT_PORT — composed as http://{HOST}:{PORT}

3. http://127.0.0.1:8765 — hardcoded default

Security

• This server only connects to http://127.0.0.1:8765 (localhost)

• It does not read/write Anki SQLite databases directly

• It does not upload any data externally

• ANKI_CONNECT_KEY is never logged

• Dangerous operations (delete, sync, import, export) are not in v0.1.0

First-Time Setup

1. Create a Test::MCP deck before making real changes

2. Run ping and check_anki_connection to verify connectivity

3. Use add_notes with dryRun: true to preview before writing

4. Never expose port 8765 to the network
