How to Use the Crypto Trading Signals API — Free REST + MCP Server

#crypto #api #trading #mcp

Every trading bot needs reliable signals. RSI divergence, MACD crossover, Bollinger Band squeeze — manually calculating these across multiple pairs is a nightmare. This API does it in one call.

Use as an MCP Server in Claude or Cursor

Add this to your MCP config and your AI assistant can query live crypto signals:

{
  "mcpServers": {
    "crypto-signal": {
      "url": "https://api.lazy-mac.com/crypto-signal/mcp"
    }
  }
}

Then just ask Claude: "What's the current RSI for ETHUSDT?" — it calls the API automatically.

Python Example

import requests

signal = requests.get(
    "https://api.lazy-mac.com/crypto-signal/api/v1/signal/ETHUSDT"
).json()

if signal["signal"]["action"] == "BUY":
    print(f"BUY signal! Confidence: {signal['signal']['confidence']}")
