MCP SERVER · OFFICIAL PROJECTSend LINE messages from your Official Account — to one person or to everyone following it — and change the rich menu they see.
LABSCO SUMMARY
Broadcast and quota sit in the same surface, which is the pairing that matters: get_message_quota tells you what a broadcast costs against the monthly limit before it goes. create_rich_menu goes further than an API wrapper — it generates and uploads the menu image from the actions you describe, so the buttons people tap can change from inside the conversation.
LINE's own MCP server for a LINE Official Account, 12 tools: push and broadcast text and Flex messages, read a user's profile, check the monthly message quota, list follower IDs, and create, set and delete rich menus.
A LINE Official Account and its channel access token — the server reads CHANNEL_ACCESS_TOKEN, plus DESTINATION_USER_ID for the default recipient — and Node.js on the machine. Apache-2.0.
One command plus a key — npx @line/line-bot-mcp-server, then supply credentials
USE CASES
Check what is left of the monthly allowance, then send it as text or as a card.
Look up who they are, then send the bubble or carousel that answers them.
Build the menu from the actions it should offer and make it the default.
Read the quota and the follower count before committing to a campaign.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
broadcast_flex_messageBroadcast a highly customizable flex message via LINE to all users who have added your LINE Official Account. Supports both bubble (single container) and carousel (multiple swipeable bubbles) layouts. Please be aware that this message will be sent to all users.
