• ⚡ Async Architecture: High-performance asynchronous I/O operations
• 📝 Rich Logging: Structured logging
• 🔧 Flexible Configuration: Support for environment variables and configuration files

git clone https://github.com/yourusername/ibkr-mcp-server.git
cd ibkr-mcp-server

# Create virtual environment
python3 -m venv venv
source venv/bin/activate

# Install the package
pip install -e .

# Install development dependencies
pip install -e ".[dev]"

# Setup pre-commit hooks
pre-commit install

Create a .env file in the project root:

# MCP Server Settings
MCP__HOST=0.0.0.0
MCP__PORT=8080

# IBKR Connection Settings
IBKR__HOST=127.0.0.1
IBKR__PORT=7497
IBKR__CLIENT_ID=1
IBKR__READONLY=false

# Logging Settings
LOGGING__LEVEL=INFO

# Test IBKR connection
python -m ibkr_mcp_server.cli test --host 127.0.0.1 --port 7497

# Start server
python -m ibkr_mcp_server.cli serve

# Or with custom parameters
python -m ibkr_mcp_server.cli serve --host 0.0.0.0 --port 8080

The server provides 9 MCP tools:

• get_account_summary: Get account summary information
• get_positions: Get position information

• place_order: Place an order
• cancel_order: Cancel an order
• get_open_orders: Get open orders

• get_market_data: Get real-time market data
• get_historical_data: Get historical data

• connection_status: Check connection status
• reconnect: Reconnect to IBKR
