Futures Trading Details

Position Modes

• One-way Mode: Single position per symbol
  • Default mode, simpler position management
  • Total position size is the sum of all orders
• Hedge Mode: Separate long and short positions
  • Allows holding both long and short positions simultaneously
  • Each position has independent margin requirements

Margin Types

• Isolated Margin: Fixed margin per position
  • Risk is limited to the allocated margin
  • Each position has its own leverage setting
• Cross Margin: Shared margin across positions
  • Higher capital efficiency
  • Shared risk across all positions

Funding Rate

Perpetual futures contracts use funding rates to keep futures prices aligned with spot prices:

• Positive rate: Longs pay shorts
• Negative rate: Shorts pay longs
• Payments occur every 8 hours

Security Considerations

Spot Trading Security

• Never commit API keys to version control
• Use environment variables or secure key storage
• Restrict API key permissions to only required operations
• Regularly rotate your API keys

Futures Trading Security

• Set appropriate leverage limits based on risk tolerance
• Always use stop-loss orders to limit potential losses
• Monitor liquidation prices carefully
• Regularly check position risks and margin ratios
• Consider using reduce-only orders for risk management
• Be cautious with cross-margin due to shared risk

Rate Limits

• Respect Binance API rate limits
• Default rate limits:
  • 1200 requests per minute for order operations
  • 100 requests per second for market data
• Implement proper error handling for rate limit errors

Error Handling

Common Error Scenarios

• Invalid API credentials
• Insufficient balance or margin
• Invalid order parameters
• Rate limit exceeded
• Network connectivity issues

Futures-Specific Errors

• InsufficientMarginError: Not enough margin for operation
• InvalidPositionModeError: Wrong position mode setting
• OrderValidationError: Invalid futures order parameters

Example error handling:

try {
  await createFuturesOrder({
    symbol: 'BTCUSDT',
    side: 'BUY',
    type: 'LIMIT',
    quantity: '0.001',
    price: '40000',
    timeInForce: 'GTC'
  });
} catch (error) {
  if (error instanceof InsufficientMarginError) {
    console.error('Insufficient margin available');
  } else if (error instanceof InvalidPositionModeError) {
    console.error('Invalid position mode');
  } else if (error instanceof OrderValidationError) {
    console.error('Invalid order parameters');
  }
}

BINANCE_API_KEY=your_api_key_here
BINANCE_API_SECRET=your_secret_key_here

2. Install dependencies:

pnpm install

Build the server:

pnpm build

For development with auto-rebuild:

pnpm watch

Installation

Installing via Smithery

To install Binance Trading Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install mcp-server-cex-bn --client claude

Installing manually

1. Clone the repository
2. Install dependencies:

pnpm install

3. Configure your Binance API credentials in .env
4. Build and start the server:

pnpm start

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

pnpm inspector

The Inspector will provide a URL to access debugging tools in your browser.
