What is line-oa-mcp-ultimate?

LINE OA MCP Ultimate is a server that connects AI assistants like Claude or Cursor to your LINE Official Account, letting you operate the account through plain conversation instead of clicking through the LINE dashboard manually. LINE is a messaging app widely used in Asia, particularly in Thailand, Japan, and Taiwan, and businesses use LINE Official Accounts to broadcast messages, run promotions, and communicate with customers at scale. Once the server is set up, you can ask your AI assistant to do things like send a promotional message to a specific audience, summarize last week's engagement statistics, build a rich menu (the custom button panel that appears at the bottom of a chat), or create a coupon and check how many people redeemed it. The AI translates those requests into the appropriate LINE API calls behind the scenes. You provide intent, the server handles the technical details. The package includes 27 tools covering the main areas of LINE OA management: sending messages in several formats, creating and managing rich menus, building Flex messages (highly formatted visual cards) from pre-made templates, constructing retargeting audiences from customer lists or from people who clicked a previous broadcast, pulling analytics reports, and managing coupons. There are also tools for agencies that manage multiple client accounts and need to switch between them or run the same operation across all of them at once. Setup requires Node.js and a LINE Channel Access Token, which you get from the LINE Developers Console. There is no database, no server to host, and no public URL required. You paste a short configuration block into your AI host's settings file, restart the app, and the tools become available. The project notes it is aimed at small business owners and marketers who already rely on LINE as their primary customer channel, as well as developers building LINE-integrated software. The project is independent, not affiliated with LINE Corp, and is licensed under MIT.
