About LINE Bot MCP Server

An official MCP server by LINE that bridges AI agents (such as Claude Desktop or Cline) and the LINE Messaging API. It exposes 12 tools covering messaging (push and broadcast of text and flex messages), user profile retrieval, message quota, rich menu management, and follower ID listing. The server communicates over stdio and authenticates with a LINE Channel Access Token. It can be run via npx (Node.js v22+) or as a Docker container.

Tools & capabilities (12)

push_text_message

Push a simple text message to a user via LINE. Recipient defaults to DESTINATION_USER_ID if userId is not provided.

push_flex_message

Push a highly customizable flex message (bubble or carousel) to a user via LINE, with required alt text.

broadcast_text_message

Broadcast a simple text message to all users who have followed your LINE Official Account.

broadcast_flex_message

Broadcast a highly customizable flex message (bubble or carousel) to all users who have added your LINE Official Account.

get_profile

Get detailed profile information of a LINE user including display name, profile picture URL, status message, and language.

get_message_quota

Delete a rich menu from your LINE Official Account by richMenuId.

set_rich_menu_default

What this server can do

LINE Bot MCP Server provides tools for these capabilities — tap one to see every MCP server that does the same:

Send team messages

When to use it

  • Letting an AI agent send notifications or replies to LINE users directly from a conversation
  • Broadcasting announcements to all followers of a LINE Official Account
  • Building and managing rich menus for a LINE Official Account programmatically
  • Retrieving user profiles and follower IDs to drive personalized messaging
  • Monitoring monthly message quota and consumption for the account

Security notes

Requires a LINE Channel Access Token (CHANNEL_ACCESS_TOKEN) passed as an environment variable; treat it as a secret. The npx config sets NPM_CONFIG_IGNORE_SCRIPTS=true to skip package install scripts. Broadcast tools send messages to all followers of the Official Account, so use with care.

LINE Bot MCP Server FAQ

Is this an official LINE project?

Yes. It is published by the LINE organization on GitHub and distributed as the @line/line-bot-mcp-server npm package. It is currently provided as a preview version.

What credentials do I need?

A LINE Channel Access Token (CHANNEL_ACCESS_TOKEN) is required. A DESTINATION_USER_ID is optional but required when a tool's input does not include a userId.

How can I run it?

Via npx with @line/line-bot-mcp-server (requires Node.js v22+), or via a Docker image you build from the repository. Both are configured as an mcpServers entry in your AI agent.

How do I test it locally?

After cloning, installing, and building, you can run the MCP Inspector with: npx @modelcontextprotocol/inspector node dist/index.js -e CHANNEL_ACCESS_TOKEN=... -e DESTINATION_USER_ID=...
