## Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.
This guide walks you through the easiest and most secure way to connect your BytePlus Ark account to Claude via Composio Connect, enabling it to create 10s promo video from script, check status of latest video task, cancel pending video generation task now, and more such actions on your behalf without compromising your account security.
Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

## Connect BytePlus Ark to Claude Cowork

### Connecting BytePlus Ark to Claude Web, Desktop, and Cowork
1. Open Customize
In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.
2. Add the Composio MCP server
Click Add custom connector and paste in the Composio MCP server URL:

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

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

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `BYTE_PLUS_ARK_CANCEL_OR_DELETE_VIDEO_TASK` | Cancel or Delete Video Task | Irreversibly cancel a video generation task when it is queued, or permanently delete its task record when it is terminal. BytePlus Ark chooses the effect from the task's current status; the caller cannot select cancel versus delete. Check the task with Get Video Task first and use only an intended disposable task. |
| `BYTE_PLUS_ARK_CREATE_VIDEO_TASK` | Create Video Task | Start a potentially billable asynchronous video generation task and return its task ID. Model capabilities and optional parameter support vary. A callback URL, if supplied, may receive task-status POSTs. |
| `BYTE_PLUS_ARK_GET_VIDEO_TASK` | Get Video Task | Retrieve one video generation task's status, failure details, and generated output URLs by task ID. |
| `BYTE_PLUS_ARK_LIST_VIDEO_TASKS` | List Video Tasks | Return one page of video generation tasks, optionally filtered by status, task IDs, model, or service tier. |

## Troubleshooting

### 1. Why does Claude not use the Composio connector for BytePlus Ark?

The connector can show as connected, but Claude must use it in each BytePlus Ark conversation.
- Click + at the lower left of the chat, or type /.
- Hover Connectors.
- Turn on Composio.
- Ask Claude to connect to BytePlus Ark again.

### 2. Why does Claude show an MCP server error before BytePlus Ark connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for BytePlus Ark.
- Check that the connector URL is https://connect.composio.dev/mcp.
- Connectors run from Anthropic's cloud, so your device network is usually not the problem.
- Add the connector again from Customize > Connectors, then ask Claude to connect BytePlus Ark.
- If it fails again, send the error and the ofid_ reference id to support@composio.dev.

### 3. Why does the BytePlus Ark authorization link not work?

The Composio connector is one server. Your BytePlus Ark account connects separately when Claude asks for it.
- If the browser does not open, or the link expires, ask Claude to retry the BytePlus Ark connection.
- Composio creates a fresh BytePlus Ark authorization link.
- Open that link in your browser and finish the BytePlus Ark sign-in.

### 4. Why do BytePlus Ark actions fail after they worked before?

The BytePlus Ark connection can expire or lose permission.
- Ask Claude to inspect the BytePlus Ark connection.
- If the connection is unhealthy, disconnect it when Claude prompts you.
- Reconnect the BytePlus Ark account and retry the action.
- If Claude shows a permission prompt, approve it before Claude changes data in BytePlus Ark.
- If the action still fails with a permission error, check that the connected account has that permission in BytePlus Ark itself.

### 5. How do I switch to a different BytePlus Ark account?

Claude can manage the BytePlus Ark connection for you.
- Ask Claude to disconnect or delete the current BytePlus Ark account.
- Ask Claude to connect BytePlus Ark again.
- Open the new Composio authorization link for BytePlus Ark.
- Sign in with the other BytePlus Ark account in the browser.
- After the account connects, ask Claude to retry the BytePlus Ark task.

### 6. Why is my BytePlus Ark connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your BytePlus Ark connection works in Claude Web, Desktop, and Cowork.
- In Claude Desktop, open Customize > Connectors.
- Next to Composio, click ⋮ and click Clear cache.
- If BytePlus Ark tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
- On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect BytePlus Ark.

## Creating MCP Server - Stand-alone vs Composio SDK

The BytePlus Ark MCP server connects Claude Web, Desktop, and Cowork to your BytePlus Ark account through Composio. Once connected, Claude can use the available BytePlus Ark tools and triggers to complete tasks on your behalf.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and BytePlus Ark MCP?

With a standalone BytePlus Ark MCP server, the agents and LLMs can only access a fixed set of BytePlus Ark tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from BytePlus Ark 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 BytePlus Ark tools.

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

Yes, absolutely. You can configure which BytePlus Ark 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 BytePlus Ark data and credentials are handled as safely as possible.
