Overview

This server acts as a bridge between the Model Context Protocol and the LINE Messaging API. It enables AI agents to interact with LINE Official Accounts by sending text and customizable flex messages, either to specific users or via broadcast to followers.

Our verdict

With a security score of 45/100, this server is classified as high-risk. The evaluation highlights that critical security components, specifically OAuth and read-only mode support, have not yet been editorially reviewed. Because the repository explicitly warns that this is a preview version with potentially incomplete functionality, it should only be utilized in experimental environments rather than mission-critical production systems.

  • Supports customizable flex message layouts
  • Small footprint with only five direct dependencies
  • Provides access to account-level metrics like message quotas
  • Active development with recent commits
  • OAuth and read-only mode support are not reviewed
  • Labeled as a preview version with incomplete support
  • No official vendor maintenance

Setup

Claude Desktop
{
  "mcpServers": {
    "line-bot-mcp-server": {
      "args": [
        "-y",
        "@line/line-bot-mcp-server"
      ],
      "command": "npx"
    }
  }
}

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Some servers require API keys or tokens as environment variables — check the project's README and add an "env" object if needed.

  • No read-only mode — running this grants full read/write access.
  • No built-in authentication — anyone with access to this config can invoke every tool it exposes.
