💡 Usage Examples

Market Discovery

Ask Claude:

"Show me the top 10 trending markets on Polymarket in the last 24 hours" "Find all crypto markets about Bitcoin" "What sports markets are closing in the next 12 hours?" "Search for markets about Trump"

Market Analysis

"Analyze the trading opportunity for the government shutdown market" "Compare these three markets and tell me which has the best risk/reward" "What's the current spread on the Eagles vs Packers market?" "Show me the orderbook depth for token ID xyz"

Autonomous Trading

"Buy $100 of YES tokens in [market_id] at $0.65" "Place a limit order: sell 200 NO at $0.40 in [market]" "Execute a smart trade: buy YES up to $500 in [market] using best strategy" "Cancel all my open orders in the government shutdown market" "Rebalance my position in [market] to $1000 with max 2% slippage"

Portfolio Management

"Show me all my current positions" "What's my total portfolio value?" "Analyze my portfolio risk and suggest improvements" "What's my P&L for the last 30 days?" "Which are my best and worst performing markets?" "Suggest portfolio optimizations for a conservative strategy"

Real-time Monitoring

"Subscribe to price changes for the government shutdown markets" "Monitor my order status in real-time" "Alert me when the Eagles vs Packers market moves more than 10%" "Show me real-time orderbook updates for [token_id]"

🧪 Testing

# Install dev dependencies pip install -e ".[dev]" # Run all tests pytest # Run specific test suite pytest tests/test_trading_tools.py -v # Run with coverage pytest --cov=polymarket_mcp --cov-report=html # Run market analysis demo python demo_mcp_tools.py

Note: All tests use real Polymarket APIs - NO MOCKS!

🛡️ Safety & Security

⚠️ Important Security Considerations

Private Key Protection: Never share or commit your private key
Start Small: Begin with small amounts ($50-100) to test
Understand Markets: Only trade in markets you understand
Monitor Positions: Check your positions regularly
Use Safety Limits: Configure appropriate limits for your risk tolerance
Never Risk More: Than you can afford to lose

Default Safety Limits

MAX_ORDER_SIZE_USD=1000 # Maximum $1,000 per order MAX_TOTAL_EXPOSURE_USD=5000 # Maximum $5,000 total exposure MAX_POSITION_SIZE_PER_MARKET=2000 # Maximum $2,000 per market MIN_LIQUIDITY_REQUIRED=10000 # Minimum $10,000 market liquidity MAX_SPREAD_TOLERANCE=0.05 # Maximum 5% spread REQUIRE_CONFIRMATION_ABOVE_USD=500 # Confirm orders over $500

These can be customized in your .env file or Claude Desktop config.
