This MCP Server provides a robust interface for Binance spot trading operations.

中文说明

Features

Trading Operations

• Configure and store Binance API credentials securely
• Execute spot trading operations (LIMIT/MARKET orders)
• Monitor account balances
• Track and manage open orders
• Cancel existing orders

Tools

configure_api_keys

Securely store your Binance API credentials:

await configureBinanceApiKeys({
  apiKey: 'your-api-key',
  apiSecret: 'your-api-secret'
});

create_spot_order

Create LIMIT or MARKET orders:

// LIMIT order
await createSpotOrder({
  symbol: 'BTCUSDT',
  side: 'BUY',
  type: 'LIMIT',
  quantity: '0.001',
  price: '40000'
});

// MARKET order
await createSpotOrder({
  symbol: 'BTCUSDT',
  side: 'BUY',
  type: 'MARKET',
  quantity: '0.001'
});

cancel_order

Cancel an existing order:

await cancelOrder({
  symbol: 'BTCUSDT',
  orderId: '12345678'
});

get_balances

Check your account balances:

const balances = await getBalances();
// Returns: { BTC: '0.1', USDT: '1000', ... }

get_open_orders

List all open orders:

const orders = await getOpenOrders({
  symbol: 'BTCUSDT' // Optional: specify symbol
});

Security Considerations

• Never commit your 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

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
• Invalid order parameters
• Rate limit exceeded
• Network connectivity issues

Example error handling:

try {
  await createSpotOrder({
    symbol: 'BTCUSDT',
    side: 'BUY',
    type: 'LIMIT',
    quantity: '0.001',
    price: '40000'
  });
} catch (error) {
  if (error.code === -2010) {
    console.error('Insufficient balance');
  } else if (error.code === -1021) {
    console.error('Rate limit exceeded');
  }
}

Development

1. Set up environment variables:

create .env file in the root directory, and set your Binance API credentials:

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

1. Clone the repository
2. Install dependencies:

pnpm install

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

pnpm build
pnpm start

### Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector), which is available as a package script:

```bash
pnpm inspector

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