Installation

Set up this MCP server in your favorite AI agent — copy a ready-made configuration below.

Any MCP-compatible agent

Most agents (Claude, Cursor, Windsurf, VS Code, and more) read a standard mcpServers configuration.

  1. Open your agent's MCP configuration file.
  2. Merge the snippet below into it, filling in the environment variables with your own values.
  3. Restart the agent — the "LINE Bot MCP Server" tools will be available.

Description

This is LINE's own MCP server for driving a LINE Official Account from an agent. It wraps the Messaging API in twelve tools: pushing a plain text or Flex message to a specific user, broadcasting either kind to every follower, fetching a user's profile (display name, picture, status message, language), and checking the account's monthly message quota and current consumption.

Rich menus get first-class treatment, which is the part that is genuinely tedious to do by hand. create_rich_menu takes up to six actions — postback, message, URI, date/time picker, camera, camera roll, location, rich-menu switch or clipboard — then generates and uploads the menu image and sets it as default in one step. Listing, deleting, setting and cancelling the default menu are separate tools. get_follower_ids paginates through the users who have added the account, so a workflow can address people without a hand-maintained list.

Setup needs Node.js 22+, a LINE Official Account with the Messaging API enabled, and a long-lived channel access token in CHANNEL_ACCESS_TOKEN. A DESTINATION_USER_ID can be set as the default recipient for tools that take an optional userId.

LINE describes the repository as a preview release: functionality and support are not yet complete.
