LINE Messaging integration

LINE Messaging API v2 for official accounts: push, multicast, broadcast and narrowcast messages, reply to a webhook event, manage rich menus, read user profiles and group memberships, download the media a user sent, and check the monthly message quota. The channel access token travels as a bearer token.

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Use LINE Messaging from Claude Code, Cursor or Codex

Connect LINE Messaging in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its LINE Messaging operations become tools the client can call, next to every other integration you connected.
