It's an MCP (Model Context Protocol) server that connects LINE to your AI, giving the agent tools to act on your data — through a single remote link.

Which AI clients does it work with?

Any MCP-compatible client: Claude (web, desktop and mobile), Cursor, ChatGPT with connectors, OpenClaw and other agents.

No. Paste the remote URL into your client, authenticate once, and you're done — no packages to install, no code to write.

Is it secure? Can the AI change my data?

Access is authorized by you and can be revoked anytime. Permissions follow what LINE exposes; you approve them when connecting.

How much does it cost?

You start free and upgrade when you need more usage. Billing and limits are managed in your mcp.ai account.

Can I cancel anytime?

Yes. Plans are monthly and can be cancelled at any time, with no lock-in.

LINE

Tools (13)

line_create_rich_menuCreate 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.

line_create_rich_menu_with_imageCreate 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

line_delete_rich_menuPermanently delete a rich menu by ID. Delete only a menu the caller owns or explicitly intends to remove.

line_download_message_content_previewDownload LINE's reduced-size preview image for a retained image or video message whose contentProvider.type is line.

line_get_message_delivery_countGet 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.

line_get_rich_menuGet one Messaging API rich-menu definition by ID, including its canvas, tappable areas, and actions.

line_link_or_unlink_user_rich_menuLink 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 accept

line_list_chat_member_idsReturn 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.

line_list_follower_idsReturn 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

line_list_rich_menusList all rich menus created through the Messaging API. Menus created in LINE Official Account Manager are not included.

line_mark_messages_as_readMark 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.

line_set_or_clear_default_rich_menuSet 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.

line_upload_rich_menu_imageUpload 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.
