IB Portfolio Tracker - MCP Server

An MCP (Model Context Protocol) server that connects Claude AI to your Interactive Brokers account for real-time portfolio tracking, financial news, and sentiment analysis.

What Can You Do?

Once set up, you can ask Claude things like:

• "What's my portfolio value?"

• "Show my positions with P&L"

• "Give me a full news analysis for NVDA" (combines IB + Finnhub + sentiment)

• "What's the sentiment around Tesla?"

• "Show historical data for SPY"

• "What news providers are available from IB?"

All responses come directly from your Interactive Brokers account, IB news feeds (Reuters, Dow Jones, etc.), and optionally Finnhub API.

Quick Start

Prerequisites

• macOS, Linux, or Windows

• Python 3.10+ installed

• Interactive Brokers account

• Claude Desktop or Claude Code (VS Code)

Step 1: Download IB Gateway

IB Gateway is a lightweight app that allows API access to your IBKR account.

1. Download from: https://www.interactivebrokers.com/en/trading/ibgateway-stable.php

2. Install and log in with your IBKR credentials

3. Configure API settings:

   • Go to Configure → Settings → API → Settings

   • Set Socket port to 4001

   • Check Read-Only API (recommended for safety)

4. Keep IB Gateway running whenever you want to use the portfolio features

Note: IBKR Desktop app does NOT support API connections. You need IB Gateway or TWS.

Step 2: Get a Finnhub API Key (Optional)

Finnhub provides additional news and social sentiment data. This is optional - IB native news works without it.

1. Sign up at: https://finnhub.io/register

2. Copy your API key from the dashboard

3. Free tier: 60 requests/minute (plenty for personal use)

Step 3: Install the MCP Server

# Clone or download this repository
git clone https://github.com/vinbg/ib-mcp-server.git
cd ib-mcp-server

# Run the setup script
# Mac/Linux:
chmod +x setup.sh
./setup.sh

# Windows:
setup.bat

The setup script will:

• Create a Python virtual environment

• Install all dependencies

• Guide you through configuration

• Test your connections

Step 4: Configure Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "ib-portfolio": {
      "command": "/FULL/PATH/TO/ib-mcp-server/.venv/bin/python",
      "args": ["-m", "ib_mcp.server"],
      "cwd": "/FULL/PATH/TO/ib-mcp-server"
    }
  }
}

Replace /FULL/PATH/TO/ with your actual path!

Then restart Claude Desktop (Cmd+Q, then reopen).

Optional: Add LunarCrush for Crypto Sentiment

LunarCrush provides social sentiment data for cryptocurrencies. To add it alongside this server:

1. Get an API key at: https://lunarcrush.com/developers

2. Add to your Claude Desktop config:

{
  "mcpServers": {
    "ib-portfolio": {
      "command": "/FULL/PATH/TO/ib-mcp-server/.venv/bin/python",
      "args": ["-m", "ib_mcp.server"],
      "cwd": "/FULL/PATH/TO/ib-mcp-server"
    },
    "LunarCrush": {
      "type": "http",
      "url": "https://lunarcrush.ai/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_LUNARCRUSH_API_KEY"
      }
    }
  }
}

Now you can ask Claude about crypto social sentiment alongside your IBKR portfolio!

# Logging
LOG_LEVEL=INFO

Port Reference

Security

This server is READ-ONLY by default:

• No order placement capabilities

• No account modification

• API keys stored locally in .env (never committed to git)

• Works with IB's "Read-Only API" setting

Your credentials never leave your machine. The MCP server runs locally and communicates only with:

• IB Gateway on localhost

• Finnhub API (for news)

Troubleshooting

"Cannot connect to IB Gateway"

1. Is IB Gateway running? Check your dock/taskbar

2. Correct port? Verify port in IB Gateway matches your .env

3. API enabled? In IB Gateway: Configure → Settings → API → Settings

4. Firewall? Ensure localhost connections aren't blocked

"Invalid API key" (Finnhub)

1. Check your key at https://finnhub.io/dashboard

2. Verify it's correctly copied to .env

3. Free tier limit: 60 requests/minute

"Tool not found" in Claude

1. Restart Claude Desktop completely (Cmd+Q)

2. Check the config file path is correct

3. Verify Python path: which python3 in terminal

Test the connection manually

cd ib-mcp-server
source .venv/bin/activate
python -c "
from ib_async import IB
import asyncio

async def test():
    ib = IB()
    await ib.connectAsync('127.0.0.1', 4001, clientId=99)
    print('Connected!')
    print('Accounts:', ib.managedAccounts())
    ib.disconnect()

asyncio.run(test())
"
