# Copilot in Claude Code

### Summary

This guide shows you how to install and configure the DataFlint MCP (Model Context Protocol) server in Claude Code.

The entire process takes just a few minutes.

The steps are:

1. Prerequisites - Ensure you have the required tools installed
2. Add DataFlint MCP to Claude Code
3. Authenticate with your organization
4. Verify the installation

### Prerequisites

Before installing the DataFlint MCP server, ensure you have:

* **Node.js** (version 18 or higher) installed on your system
* **npm** or **npx** available in your command line
* **Claude Code** installed and available as `claude` in your terminal
* Your **organization's customer domain** — only for BYOC (bring your own cloud) customers. Contact your DataFlint admin if you do not know it.

### Installation

#### Step 1: Add DataFlint MCP to Claude Code

Open a terminal and run one of the following commands.

**For SaaS customers:**

```bash
claude mcp add dataflint -- npx -y @dataflint/mcp-server@latest
```

**For BYOC (bring your own cloud) customers:**

```bash
claude mcp add dataflint -- npx -y @dataflint/mcp-server@latest --customer-domain YOUR_COMPANY_NAME
```

{% hint style="info" %}
Replace `YOUR_COMPANY_NAME` with your customer domain. SaaS customers do not need this flag.
{% endhint %}

#### Step 2: First-time authentication

When you first use DataFlint MCP in Claude Code:

1. Your browser will automatically open to your organization's authentication page
2. Log in with your organization credentials
3. Future uses will not require browser authentication

After successful authentication, you can close the browser and return to Claude Code.

Then you can ask Claude questions, with or without the prompt, such as:
