Anki MCP Server

A Model Context Protocol (MCP) server that enables LLMs to interact with Anki flashcard software through AnkiConnect.

Features

Tools

- anki_check_connection - Check whether AnkiConnect is reachable
- anki_list_decks - List all available Anki decks, optionally with deck IDs
- anki_create_deck - Create a new Anki deck
- anki_list_tags - List all tags currently used in the collection
- anki_add_note_tags - Add tags to one or more notes
- anki_remove_note_tags - Remove tags from one or more notes
- anki_create_note - Create a new note
- anki_batch_create_notes - Create multiple notes at once
- anki_search_notes - Search for notes using Anki query syntax
- anki_get_note_info - Get detailed information about a note
- anki_update_note - Update an existing note's fields and/or tags
- anki_delete_note - Delete one or multiple notes
- anki_list_note_types - List all available note types
- anki_create_note_type - Create a new note type
- anki_get_note_type_info - Get detailed structure of a note type
- anki_sync - Trigger AnkiWeb sync (fire-and-forget; success means Anki accepted the request, not that AnkiWeb received the data; a blocking dialog in Anki can silently keep the sync queued)

Legacy unprefixed tool names such as create_note and list_decks remain callable for existing clients, but new agent integrations should use the anki_* names.

Resources

- anki://tags/all - Complete list of tags
- anki://note-types/all - List of all available note types
- anki://note-types/all-with-schemas - Detailed structure information for all note types

Prerequisites

1. Anki installed on your system
2. AnkiConnect add-on installed in Anki
3. Node.js 20.11 or newer

Configuration

Install via Desktop Extension (.mcpb)

This repository supports Anthropic Desktop Extensions (MCPB). The easiest way to use this server in Claude Desktop is by installing the packaged .mcpb bundle.

1. Generate the .mcpb file locally using the provided script:

npm run mcpb

2. Open Claude Desktop Settings → Extensions and drag the generated .mcpb file in, then click Install.

This validates manifest.json and outputs a .mcpb archive you can install as above. Learn more about Desktop Extensions in Anthropic's announcement: Desktop Extensions: One-click MCP server installation for Claude Desktop.

Usage with Claude Desktop

Add the server to your claude_desktop_config.json:

{
  "mcpServers": {
    "anki": {
      "command": "npx",
      "args": ["--yes", "anki-mcp-server"]
    }
  }
}

Using Custom AnkiConnect Port

If your AnkiConnect is running on a different port, you can specify it using the --port parameter:

{
  "mcpServers": {
    "anki": {
      "command": "npx",
      "args": ["--yes", "anki-mcp-server", "--port", "8080"]
    }
  }
}

Configuration for Cline

Add the server to your Cline MCP settings file inside VSCode's settings cline_mcp_settings.json

{
  "mcpServers": {
    "anki": {
      "command": "npx",
      "args": ["--yes", "anki-mcp-server"]
    }
  }
}

Using Custom AnkiConnect Port

For Cline, you can also specify a custom port:

{
  "mcpServers": {
    "anki": {
      "command": "npx",
      "args": ["--yes", "anki-mcp-server", "--port", "8080"]
    }
  }
}

Agent Skills (Claude Code)

Install the Anki skill to give Claude Code built-in knowledge of all Anki tools and workflows:

npx skills add nailuoGG/anki-mcp-server@anki

Once installed, Claude Code will automatically use the skill when you ask it to create flashcards, manage decks, or batch import notes.

> Note: Do not use the .mcpb packaged version as the MCP server — it outputs Electron metadata to stdout which breaks the MCP stdio protocol. Use npx -y anki-mcp-server instead.

Development

Packaging a Desktop Extension (.mcpb)

Create a distributable Desktop Extension bundle for Claude Desktop:

npm run mcpb

This will build the project and generate a .mcpb archive from the current repository, validating manifest.json. Test by dragging it into Claude Desktop's Extensions settings. Reference: Desktop Extensions: One-click MCP server installation for Claude Desktop.

Publishing to MCP Registry

This server is automatically published to the MCP Registry when a new version is released. The publishing process includes:

1. Automated CI/CD: GitHub Actions automatically publishes to both NPM and MCP Registry on successful releases
2. Schema Validation: The server.json file is validated against the MCP schema before publishing
3. Version Synchronization: Versions are kept in sync between package.json, manifest.json, and server.json
4. Comprehensive Testing: Multi-version Node.js testing, linting, and validation before publishing
5. Beta Support: Automated beta releases for testing new features

Manual Validation

You can validate the MCP server configuration locally:

npm run validate-mcp

This will download the latest MCP schema and validate your server.json file.

Manual Publishing

If you need to publish manually, you can use the MCP Publisher CLI:

```bash
