2. **安裝 AutoHotkey v2**
   - 下載並安裝：https://www.autohotkey.com/

3. **設定 Claude Desktop**
   - 開啟 Claude Desktop 設定檔
   - 在 `mcpServers` 中加入以下設定：

```json
{
  "mcpServers": {
    "line-desktop-mcp": {
      "command": "npx",
      "args": ["line-desktop-mcp@latest"]
    }
  }
}
```

#### macOS

1. **安裝 Node.js**
   - 使用 Homebrew：`brew install node`
   - 或從官網下載：https://nodejs.org/

2. **（選擇性）安裝 cliclick**
   - 如果有安裝 Homebrew，會於啟動時自動安裝
   - 或手動安裝：`brew install cliclick`

3. **設定 Claude Desktop**
   - 開啟 Claude Desktop 設定檔
   - 在 `mcpServers` 中加入以下設定：

```json
{
  "mcpServers": {
    "line-desktop-mcp": {
      "command": "npx",
      "args": ["line-desktop-mcp@latest"]
    }
  }
}
```

### 進階設定

#### Streamable HTTP 模式

除了預設的 stdio 模式外，本專案也支援透過 Streamable HTTP 方式運行。此模式特別適合在 **n8n** 等支援 MCP 的平台中使用。

**啟動 Streamable HTTP 模式：**

```bash
# 本機使用（僅 localhost）
npx line-desktop-mcp@latest --http-mode --port 3000

# 開放外部連線（需搭配 token）
npx line-desktop-mcp@latest --http-mode --host 0.0.0.0 --port 3000 --token YOUR_SECRET
```

**參數說明：**
- `--http-mode`：啟用 Streamable HTTP 模式，使用 HTTP streaming 而非 stdio
- `--port <port>`：指定 HTTP 伺服器的 port（預設：3000）
- `--host <host>`：指定綁定的網路介面（預設：`127.0.0.1`）
- `--token <secret>`：設定 Bearer Token 驗證密鑰。當 `--host` 設為非 loopback 位址時為必填，以確保安全性

**MCP 端點配置：**

本機連接：
```
http://127.0.0.1:3000/mcp
```

Docker 中的 n8n 連接（同一台機器）：
```
http://host.docker.internal:3000/mcp
```

**傳輸方式：**
- POST 請求：發送 JSON-RPC 訊息並透過 SSE stream 接收回應
- 支援 session 管理，每個連接會獲得唯一的 session ID

**n8n 工作流程範例：**

如果您想在 n8n 中使用 LINE Desktop MCP，可以下載我們提供的範例工作流程檔案：
- 📥 [下載 n8n 工作流程範例](doc_media/LINE-Desktop-MCP-Demo-chatbot-sample.json)

此範例展示如何在 n8n 中整合 LINE Desktop MCP 建立聊天機器人工作流程。

### 使用方式

在 Claude Desktop 的對話中，您可以使用以下方式操作 LINE：

#### 1. 讀取聊天內容

```
請幫我讀取 LINE 群組『專案討論』的訊息，並作出總結
```

#### 2. 發送訊息（手動確認）

```
請幫我撰寫一個問候，發送到 LINE 群組『專案討論』中
```

Claude 會先撰寫訊息內容，等待您確認後再發送。

#### 3. 發送訊息（自動送出）

```
請幫我撰寫一個問候，發送到 LINE 群組『專案討論』中，並自動發送
```

Claude 會撰寫訊息並自動完成發送動作。

### 使用注意事項

#### 重要提醒

1. **避免干擾自動化操作**  
   本工具透過圖形使用者介面（GUI）進行自動化操作。在自動化程式執行期間，請勿同時使用滑鼠進行其他操作，以免干擾程式運作。

2. **LINE Desktop 視窗配置要求**  
   請確保 LINE Desktop 使用「展開聊天視窗」模式。在此模式下，聊天視窗會固定顯示在聊天室清單的右側，而非以獨立視窗方式開啟。

3. **多顯示器環境配置**  
   若您使用多個顯示器,請將 LINE Desktop 應用程式放置於主要顯示器（第一個顯示器）上,以確保自動化功能正常運作。

**Start Streamable HTTP Mode:**

```bash
# Local use (localhost only)
npx line-desktop-mcp@latest --http-mode --port 3000

# Allow external connections (token required)
npx line-desktop-mcp@latest --http-mode --host 0.0.0.0 --port 3000 --token YOUR_SECRET
```

**Parameters:**
- `--http-mode`: Enable Streamable HTTP mode, using HTTP streaming instead of stdio
- `--port <port>`: Specify the HTTP server port (default: 3000)
- `--host <host>`: Specify the network interface to bind (default: `127.0.0.1`)
- `--token <secret>`: Set Bearer Token authentication secret. Required when `--host` is set to a non-loopback address for security

**MCP Endpoint Configuration:**

Local connection:
```
http://127.0.0.1:3000/mcp
```

n8n in Docker (same machine):
```
http://host.docker.internal:3000/mcp
```

**Transport Method:**
- POST requests: Send JSON-RPC messages and receive responses via SSE stream
- Supports session management with unique session IDs for each connection

### Usage

In Claude Desktop conversations, you can interact with LINE in the following ways:

#### 1. Read Chat Messages

```
Please read the messages from LINE group 'Project Discussion' and summarize them
```

#### 2. Send Messages (Manual Confirmation)

```
Please write a greeting and send it to LINE group 'Project Discussion'
```

Claude will compose the message and wait for your confirmation before sending.

#### 3. Send Messages (Automatic)

```
Please write a greeting and send it to LINE group 'Project Discussion', and send it automatically
```

Claude will compose the message and automatically complete the sending action.

### Usage Precautions

#### Important Reminders

1. **Avoid Interfering with Automation**  
   This tool performs automation through the graphical user interface (GUI). During automated operations, please refrain from using the mouse for other tasks to prevent interference with the program's execution.

2. **LINE Desktop Window Configuration**  
   Please ensure that LINE Desktop is configured in "Expanded Chat Window" mode. In this mode, the chat window remains docked to the right side of the chat list, rather than opening as a separate independent window.

3. **Multi-Monitor Setup**  
   If you are using multiple monitors, please ensure that the LINE Desktop application is positioned on the primary display (first monitor) for the automation to function correctly.
