How to Set Up and Use LINE Desktop
The LINE Desktop MCP Server integrates AI tools like Claude Desktop with the LINE Desktop messaging application, enabling AI assistants to read chat messages and send messages on your behalf through GUI automation — without requiring a LINE developer account or API tokens. It works by controlling the already-logged-in LINE Desktop client using platform-native automation (AutoHotkey on Windows, accessibility APIs on macOS), making it accessible to anyone with a LINE account. This is ideal for automating LINE workflows, summarizing group chats, or building AI-powered LINE bots without touching LINE's official API.
Prerequisites
- LINE Desktop v9.10 or later installed and logged in
- Windows 10+ with AutoHotkey v2 installed (https://www.autohotkey.com/), OR macOS Ventura 13.0+
- Node.js and npx available in your PATH
- Claude Desktop (Pro plan) or another MCP-compatible client
- Single-monitor primary display setup recommended for reliable automation
Install LINE Desktop and log in
Download LINE Desktop from https://line.me/en/download and log in with your LINE account. The MCP server controls the logged-in desktop app directly, so you must be signed in before starting.
Install Node.js and AutoHotkey (Windows only)
On Windows, install Node.js from https://nodejs.org and AutoHotkey v2 from https://www.autohotkey.com/. On macOS, install Node.js via Homebrew.
# macOS
brew install node
# Windows: Download installers from official sitesAdd the LINE Desktop MCP server to your client configuration
Open your MCP client config file and add the line-desktop-mcp entry. No API keys are required — the server communicates with LINE Desktop directly.
{
"mcpServers": {
"line-desktop": {
"command": "npx",
"args": ["line-desktop-mcp@latest"]
}
}
}Restart Claude Desktop
Quit and reopen Claude Desktop so it connects to the LINE Desktop MCP server. Ensure LINE Desktop is also running and visible on your screen.
Test with a simple message read
Ask Claude to read messages from a LINE chat. The server will use GUI automation to bring LINE Desktop to focus, extract chat content, and return it to Claude.

Example natural-language commands to use in Claude Desktop after setup.

Server cannot find or control LINE Desktop window
Make sure LINE Desktop is running and visible on your primary monitor before starting Claude. The server relies on the LINE window being accessible to the OS accessibility layer.
On Windows, AutoHotkey scripts fail to run
Ensure AutoHotkey v2 (not v1) is installed. Right-click the AutoHotkey installer and run as Administrator if needed. Also check that LINE Desktop is not minimized to the system tray.
Messages are read incorrectly or from the wrong chat
Specify the exact chat or group name in your prompt. Keep LINE Desktop on the primary display with single-monitor setup and avoid switching windows while automation is running.
