## What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.
With Composio Connect, Cowork can securely access apps like LINE through MCP without you sharing account credentials directly with the agent.

## What is the LINE MCP server, and what's possible with it?

The LINE MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your LINE account. It provides structured and secure access so your agent can perform LINE operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `LINE_CREATE_RICH_MENU` | 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. |
| `LINE_CREATE_RICH_MENU_WITH_IMAGE` | 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. |
| `LINE_DELETE_RICH_MENU` | Delete Rich Menu | Permanently delete a rich menu by ID. Delete only a menu the caller owns or explicitly intends to remove. |
| `LINE_DOWNLOAD_MESSAGE_CONTENT_PREVIEW` | Download Message Content Preview | Download LINE's reduced-size preview image for a retained image or video message whose contentProvider.type is line. |
| `LINE_GET_MESSAGE_DELIVERY_COUNT` | 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. |
| `LINE_GET_RICH_MENU` | Get Rich Menu | Get one Messaging API rich-menu definition by ID, including its canvas, tappable areas, and actions. |
| `LINE_LINK_OR_UNLINK_USER_RICH_MENU` | 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. |
| `LINE_LIST_CHAT_MEMBER_IDS` | 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. |
| `LINE_LIST_FOLLOWER_IDS` | 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. |
| `LINE_LIST_RICH_MENUS` | List Rich Menus | List all rich menus created through the Messaging API. Menus created in LINE Official Account Manager are not included. |
| `LINE_MARK_MESSAGES_AS_READ` | 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. |
| `LINE_SET_OR_CLEAR_DEFAULT_RICH_MENU` | 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. |
| `LINE_UPLOAD_RICH_MENU_IMAGE` | 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. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and LINE MCP?

With a standalone LINE MCP server, the agents and LLMs can only access a fixed set of LINE tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from LINE and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right LINE tools.

### Can I manage the permissions and scopes for LINE while using Tool Router?

Yes, absolutely. You can configure which LINE scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your LINE data and credentials are handled as safely as possible.
