# LINE MCP

Vendor: LINE  
Category: communication  
Auth: API_KEY  
Composio slug: `line`

Use a LINE Official Account's Messaging API channel to manage messages, audiences, and rich menus.

## Tools

- **Create Rich Menu** — Create a rich-menu definition and return its ID. Creation alone does not display it: upload an image, then set it as default or link it to a user.
- **Create Rich Menu with Image** — Create a rich-menu definition and upload its JPEG or PNG image in one call. If image upload fails, the newly created definition is deleted automatically. The finished menu must still be set as default or linked to a user to display.
- **Delete Rich Menu** — Permanently delete a rich menu by ID. Delete only a menu the caller owns or explicitly intends to remove.
- **Download Message Content Preview** — Download LINE's reduced-size preview image for a retained image or video message whose contentProvider.type is line.
- **Get Message Delivery Count** — Get the number of reply, push, multicast, or broadcast messages sent on one UTC+9 calendar date. A result can be unready, unavailable_for_privacy, or out_of_service instead of containing a count.
- **Get Rich Menu** — Get one Messaging API rich-menu definition by ID, including its canvas, tappable areas, and actions.
- **Link or Unlink User Rich Menu** — Link or unlink a per-user rich menu. WARNING: LINE can return HTTP 200 even when nothing changed for a nonexistent, deleted, blocked, non-friend, or cross-channel user; success confirms request acceptance, not the assignment effect.
- **List Chat Member IDs** — Return one page of member user IDs for a group or legacy room containing the bot. Requires a verified or premium LINE Official Account; room applies only to legacy multi-person chats.
- **List Follower IDs** — Return one page of user IDs for friends of the LINE Official Account. This endpoint requires a verified or premium LINE Official Account and excludes blockers, deleted users, and users without profile consent.
- **List Rich Menus** — List all rich menus created through the Messaging API. Menus created in LINE Official Account Manager are not included.
- **Mark Messages as Read** — Mark all messages through a webhook-issued read token as read. The token must have been received by this exact bot; this operation cannot be undone.
- **Set or Clear Default Rich Menu** — Set or clear the Messaging API default rich menu. Setting requires an image-backed rich menu; clearing does not delete the menu and does not clear a default managed in LINE Official Account Manager.
- **Upload Rich Menu Image** — Upload a JPEG or PNG image for a rich menu. An image cannot be replaced for the same rich-menu ID; create a new menu to use another image.
