Integration with Claude

MCP Configuration

Add to your Claude/MCP configuration:

{
  "mcpServers": {
    "mt4": {
      "url": "http://localhost:3605",
      "transport": "http"
    }
  }
}

Example Agent Prompts

"Check my MT4 account balance"
→ Uses mt4_get_account

"What's the current gold price?"
→ Uses mt4_get_quote({ symbol: "XAUUSD" })

"Buy 0.1 lots of XAUUSD with stop loss at 2640"
→ Uses mt4_execute_trade({ symbol: "XAUUSD", action: "buy", lots: 0.1, stopLoss: 2640 })

"Close my profitable gold positions"
→ Uses mt4_get_positions({ symbol: "XAUUSD" }) + mt4_close_position for each
