How do I use Interactive Brokers MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Interactive Brokers MCP Server get the current quote for AAPL stock" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

IB MCP Server (Local, IB Gateway Only)

Tools:

get_stock_quote → price, volume
get_option_quote → bid, ask, last

Requirements: Python 3.10+, IB Gateway running, API enabled, port 4001, localhost allowed.

Setup:

python -m venv .venv
. .venv\Scripts\Activate.ps1
pip install -r requirements.txt

Environment (defaults):

$env:IB_HOST = "127.0.0.1"
$env:IB_PORT = "4001"
$env:IB_CLIENT_ID = "19"
$env:IB_MARKET_DATA_TYPE = "1"  # 1=real-time

Run:

python -m ib_mcp.server

Cursor MCP config example:

{
  "mcpServers": {
    "ib-mcp": {
      "command": "C:\\Users\\atilc\\OneDrive\\ibkrserver\\.venv\\Scripts\\python.exe",
      "args": ["-m", "ib_mcp.server"],
      "cwd": "C:\\Users\\atilc\\OneDrive\\ibkrserver",
      "env": {
        "IB_HOST": "127.0.0.1",
        "IB_PORT": "4001",
        "IB_CLIENT_ID": "19",
        "IB_MARKET_DATA_TYPE": "1"
      }
    }
  }
}

If IB Gateway is closed or not logged in, the tools will fail to fetch data—open and log in, then retry.
