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.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
