LINE Bot MCP Server is maintained by LINE and integrates its Messaging API with MCP; it exposes 12 tools covering message push and broadcast, user profiles, message quota, rich menu management and follower ID retrieval, and the repository is explicitly marked as a preview version. It suits users who already have a LINE Official Account and want an AI Agent to handle messaging and account operations, but the Channel Access Token must be protected carefully and broadcast or rich menu operations directly affect the live account.

LINE Bot MCP Server is an official LINE implementation of a Model Context Protocol server that integrates the LINE Messaging API to connect an AI Agent to a LINE Official Account. It exposes capabilities for pushing and broadcasting messages, retrieving user profiles, checking message quota, managing rich menus, and fetching follower user IDs. The repository is marked as a preview version offered for experimental purposes, and it may not include complete functionality or comprehensive support.

Setup

Create or prepare a LINE Official Account: if you do not have one, create it following the LINE instructions; if you already have one, enable the Messaging API for it.
Using npx (requires Node.js v22 or later): add an mcpServers entry to your AI Agent such as Claude Desktop or Cline, with command "npx", args ["@line/line-bot-mcp-server"], and env containing NPM_CONFIG_IGNORE_SCRIPTS set to "true", CHANNEL_ACCESS_TOKEN (required) and DESTINATION_USER_ID (optional; required when the Tool's input does not include userId).
Using Docker: clone the repository, build the image with docker build -t line/line-bot-mcp-server ., then configure command "docker" with args ["run", "-i", "--rm", "-e", "CHANNEL_ACCESS_TOKEN", "-e", "DESTINATION_USER_ID", "line/line-bot-mcp-server"] and put CHANNEL_ACCESS_TOKEN and DESTINATION_USER_ID in env.
Local development with Inspector: clone the repository and cd into it, run npm install and npm run build, then run npx @modelcontextprotocol/inspector node dist/index.js -e CHANNEL_ACCESS_TOKEN="..." -e DESTINATION_USER_ID="..." to start the MCP Inspector for testing.
Notes: CHANNEL_ACCESS_TOKEN can be confirmed via the LINE long-lived channel access token instructions; DESTINATION_USER_ID can be confirmed via the LINE get-user-IDs instructions.

Generate and validate client config

Fit and risk

Best for

Developers or operations teams that already have a LINE Official Account with the Messaging API enabled
Teams that want an AI Agent to automate LINE messaging and account operations
Users of MCP-capable clients such as Claude Desktop or Cline who need LINE integration

Not for

Users without a LINE Official Account or without the Messaging API enabled
Scenarios needing stable, fully supported production functionality beyond a preview release
Environments stuck below Node.js v22 that cannot use Docker

Required permissions

Requires CHANNEL_ACCESS_TOKEN (Channel Access Token) to call the LINE Messaging API
Optionally requires DESTINATION_USER_ID as the default recipient
Requires network access to the LINE Messaging API

Risks and side effects

CHANNEL_ACCESS_TOKEN is a sensitive credential; if leaked, others could send messages or read data on behalf of the Official Account
Broadcast messages reach all followers, so misuse can cause spam or an irreversible mass send
Operations such as create_rich_menu, delete_rich_menu and set_rich_menu_default directly change the Official Account's rich menu configuration
The repository is a preview version and may not include complete functionality or comprehensive support

Troubleshooting

Confirm Node.js is v22 or later
Confirm CHANNEL_ACCESS_TOKEN is set correctly; if the tool input omits userId, also set DESTINATION_USER_ID
When using npx, confirm NPM_CONFIG_IGNORE_SCRIPTS is set to "true" in env
When using Docker, confirm the image was built with docker build and the environment variables are passed to the container correctly
For local debugging, run npm run build first, then load dist/index.js with the MCP Inspector to verify the tools are available

Use cases

Let an AI Agent push text or flex messages to a specific user on behalf of the Official Account

Broadcast notices, announcements or campaigns to all followers

Retrieve user profiles to personalize replies

Check the monthly message quota and current usage of the Official Account

Create, set as default, or delete rich menus to manage the chat interface

Fetch follower user IDs in bulk for later messaging
