# Anthropic's Messages API
Connect the Box MCP server with [Anthropic's Messages API](https://docs.anthropic.com/en/api/messages). Clone [this sample chat bot project](https://github.com/box-community/mcp-client-remote-mcp-react) to get started quickly. It allows you to have a conversation with an Anthropic model, which has access to tools provided by the Box MCP server.
## Prerequisites
* A Box enterprise account with the MCP server enabled by an admin. See [Set up the MCP server](/guides/box-mcp/setup).
* An Anthropic API key with access to the Messages API.
## Enable Box integration in Box
Admin
1. Clone the [sample chat bot project](https://github.com/box-community/mcp-client-remote-mcp-react).
2. Follow the project README to configure your Box OAuth credentials and Anthropic API key.
3. Start the application and authenticate with Box when prompted.
The sample project is a React-based chat bot that leverages Box MCP. It demonstrates how to pass the MCP endpoint and authorization token to Anthropic's Messages API:
```python theme={null}
response = await client.beta.messages.create(
model="claude-3-opus-20240229",
max_tokens=4096,
messages=conversation_history,
mcp_servers=[
{
"type": "url",
"url": "https://mcp.box.com",
"name": "box-remote-mcp",
"authorization_token": BEARER_TOKEN,
}
],
betas=["mcp-client-2025-04-04"]
)
```
