  "summary": "LINE Official Account messaging is automatable today through the Messaging API. This record is that API and the preview MCP server in the line GitHub organization. It is not the consumer LINE app, WhatsApp, or Slack. A bot server exchanges HTTPS JSON with the LINE Platform. The reference says a channel access token is required when calling the Messaging API. The overview documents reply and push messages, user profiles, rich menus, and webhooks. Message counts from LINE Official Account Manager are outside the API. Pricing has a free plan and paid plans, and the Japan example on the pricing page is not a worldwide price list. Official SDKs cover Java, PHP, Python, Node.js, Go, and Ruby. line/line-bot-mcp-server is a preview server pushed on 2026-10-15. Its README lists push and broadcast tools, profile, quota, rich menus, and related account calls, authenticated with CHANNEL_ACCESS_TOKEN. A registry search for line-bot-mcp-server returned no servers. That search does not prove the server is absent from every registry. No Messaging API CLI was established. Connector catalogs were not opened. Computer-use viability is unassessed. The API scores 7 and is the best path. The preview MCP server scores 5.\n"
