Lets Claude, Cursor and other assistants send LINE messages and manage your LINE Official Account.

This is the LINE Messaging API server from LINE's own GitHub organization. It lets your assistant send text and rich messages to one person or to every follower, look up profiles, and create or change rich menus. It runs on your computer and needs a channel access token from your LINE Official Account. LINE calls this a preview, and the broadcast tools message all your followers at once.

Good for

  • Shop and service owners who message customers through a LINE Official Account
  • Developers testing LINE Messaging API calls from their assistant
  • Teams that run LINE rich menus and need to create or swap them quickly

Install LINE Bot MCP

Claude Desktop

  1. 1

    Have these values ready, then replace the placeholders in the snippet.

    CHANNEL_ACCESS_TOKENRequiredLong-lived channel access token for your LINE Official Account.
    DESTINATION_USER_IDOptionalDefault recipient user ID when a tool call has no userId.
    NPM_CONFIG_IGNORE_SCRIPTSOptionalREADME sets it to true so npm skips install scripts.
  2. 2

    Open this file. Create it if it does not exist.

  3. 3

    Add this entry. If the file already lists servers, add it next to them.

    json
    {
  "mcpServers": {
    "line-bot": {
      "command": "npx",
      "args": [
        "@line/line-bot-mcp-server"
      ],
      "env": {
        "NPM_CONFIG_IGNORE_SCRIPTS": "true",
        "CHANNEL_ACCESS_TOKEN": "FILL_HERE",
        "DESTINATION_USER_ID": "FILL_HERE"
      }
    }
  }
}
  4. 4

    Quit and reopen Claude Desktop to load it.

Requires Node.js 22 or later, LINE Official Account with Messaging API.

The README sets NPM_CONFIG_IGNORE_SCRIPTS=true, which stops npm from running install scripts for this package and its dependencies. The first method is the README snippet as written. The second adds -y so npx does not wait for a prompt, which makes it generated. Our reading: puppeteer downloads its browser in an install script, so with scripts ignored create_rich_menu may need a Chrome you point to with PUPPETEER_EXECUTABLE_PATH (the source reads that variable).

Tools

  • Sends a text message to one LINE user

    Sends a plain text message from your Official Account to one user. The user ID comes from the call or from the default recipient you set in the config.

    Try: “Send "Your order has shipped" to user U1234.”

  • Sends a rich card message to one LINE user

    Sends a flex message, a card or carousel layout with buttons and images, to one user. It needs fallback text for devices that cannot show it.

high risk · 5 things to watch

High risk

It can message every follower of your LINE Official Account and delete rich menus, and it has no read-only mode. Use it on a test account first, and have the assistant show you any broadcast text before it sends.

What it can do

  • Read your data
  • Create and change things
  • Delete things
  • Read-only mode

Watch out for

  • It can message every follower at once

    broadcast_text_message and broadcast_flex_message send to everyone who has added your Official Account. Ask the assistant to show you the text first (our advice). github.com

  • It sends messages as your account

    push_text_message and push_flex_message send real messages to a user you name. A wrong user ID reaches the wrong person. github.com

  • It can delete and replace rich menus

    delete_rich_menu removes a menu, and create_rich_menu sets the new menu as the default for everyone. Check the menu list first. github.com

  • The token has full access to the account

    The channel access token sits in your MCP config in plain text. Our advice: keep that file out of shared repos. github.com

  • Rich menu images are drawn with a headless browser

    create_rich_menu renders its image with Puppeteer and writes a temporary HTML file to your temp folder, then deletes it. github.com

Questions

Is the LINE Bot MCP server official?

Yes. It is published by LINE's own GitHub organization (line) for the LINE Messaging API. The README calls it a preview version for experimental use, with possibly incomplete functionality and support.

What do I need to use it?

A LINE Official Account with the Messaging API turned on, a channel access token for it, and Node.js 22 or later. Put the token in CHANNEL_ACCESS_TOKEN.

What is DESTINATION_USER_ID for?

It sets a default recipient. Without it, you have to give a user ID each time you ask for a push message or a profile.

Can it send to all my followers?

Yes. The two broadcast tools send a text or a flex message to everyone who has added your Official Account.

Can I use it read-only?

No read-only switch is documented. Four tools only read (get_profile, get_message_quota, get_rich_menu_list, get_follower_ids), and the other eight send messages or change rich menus. Use a test account if you want to try it safely.

Can it run with Docker?

Yes, but you build the image yourself from the repository with docker build -t line/line-bot-mcp-server ., then point your config at it. The README shows the full config. The npx route in the install box needs no build.

Is it free?

The server is open source under Apache-2.0 and free. Sending messages follows your LINE Official Account's own plan and monthly message limit, which the quota tool reads.
