Integration with Claude

MCP Configuration

Add to your Claude/MCP configuration:

{
  "mcpServers": {
    "binance": {
      "url": "http://localhost:3606",
      "transport": "http"
    }
  }
}

Example Agent Prompts

"What's the current Bitcoin price?"
  -> Uses binance_get_ticker({ symbol: "BTCUSDT" })

"Show me the ETH order book"
  -> Uses binance_get_orderbook({ symbol: "ETHUSDT" })

"Get the last 50 hourly candles for BTC"
  -> Uses binance_get_klines({ symbol: "BTCUSDT", interval: "1h", limit: 50 })

"Check my Binance balance"
  -> Uses binance_get_account()

"Buy 0.01 BTC at market price"
  -> Uses binance_create_order({ symbol: "BTCUSDT", side: "buy", type: "market", amount: 0.01 })

---

Risk Management

The connector includes built-in risk checks:

1. Maximum Order Value: Orders exceeding MAX_ORDER_VALUE_USDT are rejected
2. Daily Volume Limit: Trading stops when MAX_DAILY_VOLUME_USDT is reached
3. Balance Check: Buy orders verify sufficient balance
4. Testnet Default: Testnet is enabled by default for safety
5. High-Risk Confirmation: Orders require explicit confirmation flag
