LINE maintains this official preview MCP server for the Messaging API. Its 13 tools send messages through a LINE Official Account, inspect profiles and quotas, list followers and groups, and create or manage rich menus.

Not for: A production support guarantee or an embedded LINE client. LINE labels the repository a preview, and the server exposes tools without an inline chat UI.

>Questions

Is the LINE Bot MCP server official?

Yes. It is published by LINE, but the README labels it a preview with incomplete functionality or support.

Is DESTINATION_USER_ID required?

Only when a tool call does not supply userId. It is useful as the default recipient but is otherwise optional.

Does it show LINE inside the MCP client?

No. The server calls the LINE Messaging API through tools; it does not register an MCP App UI.
