## Introduction

### How to integrate LINE MCP with ChatGPT Work
[ChatGPT Work](https://openai.com/chatgpt-work/) is an agent inside ChatGPT built for your most ambitious work. It takes action across your apps and files, stays with a project for hours, and turns a goal into finished materials like sheets, slides, and docs - not just answers.
In this guide, I will explain the easiest and most secure way to connect your LINE account to ChatGPT Work via Composio Connect, so it can send coupon broadcast to line followers, create rich menu for promotions, list line audience groups by size through natural language commands without ever putting your account credentials at risk.

## TL;DR

### Why use Composio over default connectors?
- Apps with read and write access. Default connectors mostly can read your data. Composio's LINE integration lets ChatGPT Work take actions like creating drafts, sending updates, labeling records, and more.
- 1,000+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
- One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
- Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
- Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

## Connect LINE to ChatGPT Work

### Prerequisites
- A ChatGPT account with access to ChatGPT Work (rolling out across Pro, Enterprise, Edu, Plus, and Business plans). We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), which is available on every plan.
- Access to the LINE workspace you want to connect.
- [Composio MCP](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt).
Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.
### Step-by-step: Connect LINE to ChatGPT Work
### 1. Open the MCP settings
In ChatGPT Work, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab.
### 2. Add the server
Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL:

```bash
https://connect.composio.dev/mcp
```

## 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 ChatGPT Work?

Yes, you can. ChatGPT Work 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.
