Prerequisites

No additional installations required for mainstream platforms. This package includes:

• Pre-configured IB Gateway for all platforms (Linux, macOS, Windows)
• Java Runtime Environment (JRE) for macOS, Windows, and standard Linux builds
• Automatic first-run musl JRE download for Alpine-based containers (e.g. node:lts-alpine, supergateway)
• All necessary dependencies

You only need:

• Interactive Brokers account (paper or live trading)
• Node.js 18+ (for running the MCP server)

Quick Start

Add this MCP server to your Cursor/Claude configuration:

{
  "mcpServers": {
    "interactive-brokers": {
      "command": "npx",
      "args": ["-y", "interactive-brokers-mcp"]
    }
  }
}

When you first use the server, a web browser window will automatically open for the Interactive Brokers OAuth authentication flow. Log in with your IB credentials to authorize the connection.

Headless Mode Configuration

For automated environments or when you prefer not to use a browser for authentication, you can enable headless mode by configuring it in your MCP server configuration:

{
  "mcpServers": {
    "interactive-brokers": {
      "command": "npx",
      "args": ["-y", "interactive-brokers-mcp"],
      "env": {
        "IB_HEADLESS_MODE": "true",
        "IB_USERNAME": "your_ib_username",
        "IB_PASSWORD_AUTH": "your_ib_password"
      }
    }
  }
}

In headless mode, the server will automatically authenticate using your credentials without opening a browser window. This is useful for:

• Automated trading systems
• Server environments without a display
• CI/CD pipelines
• Situations where browser interaction is not desired

Important: Even in headless mode, Interactive Brokers may still require two-factor authentication (2FA). When 2FA is triggered, the headless authentication will wait for you to complete the 2FA process through your confi
