IG Trading MCP

A local Python MCP server for IG's REST Trading API. It provides account/history, market data, position, working-order, and trade-confirmation tools, plus guarded OTC trade actions. This project is not affiliated with, endorsed by, or sponsored by IG Group.

Trading leveraged products can result in losses exceeding deposits. Start with an IG demo account.

Setup

1. Create a demo or live IG API key in the IG trading platform.

2. Copy .env.example to .env and set the values, or export the same variables in the MCP client's environment.

3. Install and run with uv:

uv sync
uv run ig-mcp

Required environment variables:

The server keeps OAuth tokens in memory only. It sends credentials to IG only during login and never returns tokens from tools.

MCP Client Configuration

Example configuration for a local stdio-capable MCP client:

{
  "mcpServers": {
    "ig": {
      "command": "uv",
      "args": ["--directory", "/absolute/path/to/ig-integration-mcp", "run", "ig-mcp"],
      "env": {
        "IG_API_KEY": "your-demo-key",
        "IG_IDENTIFIER": "your-identifier",
        "IG_PASSWORD": "your-password",
        "IG_ENVIRONMENT": "demo"
      }
    }
  }
}

Trade Safety

All tools that create, update, close, or cancel a trade/order require confirm: true.

When IG_ENVIRONMENT=live, they additionally require this exact parameter:

{"live_confirmation": "LIVE_TRADE_CONFIRMED"}

Use ig_get_market to inspect a market's dealing rules before submitting an order. Trade tools validate the main IG field dependencies before making API calls, but IG remains the authority for account-specific eligibility, sizes, and price rules.

Testing

uv run pytest

Tests mock all IG API traffic and do not need credentials.
