Universal MCP Server for MetaTrader 5 Trading & Data Operations

---

Overview

FullMt5McpByLeo is a complete, production-ready MCP server that enables Claude and other AI assistants to control MetaTrader 5 directly. Execute trades, retrieve market data, manage charts, analyze trading history, and automate MT5 operations through natural language.

---

Main Features (General)

• Fast execution; the MCP server is written in C++ using simdjson, super-optimized code for maximum speed. The average response time is around 10ms (from when Claude calls a function until its response; note that this may depend on the size of the request... on average it's 10ms).
• Unlike other MCPs for MT5, this MCP has two parts, one in MQL5 and the other in C++, giving access to the full MQL5 API and not limited to the mt5 package for Python, which lacks functions for handling charts, etc.

Requirements

• For repo code

• Check: dependencies.json

• For user use:

• EX5 of releases (Runner an McPServer).
• McpServer requerid a EX5 Library, and EXE for McpServer, pucharse in: TheBotPlace - McpServerByLeo

Installation of repo code

cd "C:\Users\YOUR USER\AppData\Roaming\MetaQuotes\Terminal\YOUR ID\MQL5\Shared Projects"
tsndep install "https://forge.mql5.io/nique_372/FullMt5McpByLeo.git"

• For use tsndep command requerid tsndep pacakage (avaible in pypi).. This command automatically downloads all dependencies and installs all requirements from the repositories.
• If any part of the system is private, then it will fail... contact me so I can give you access (if it's a product, you can buy it; if you have any questions, don't hesitate to contact me).

Quick Start (for final users)

1. Create a config json

Open Common\Files And create a json file with this structure:

{
  "general": {
    "type_reg": "stdio_stdin",
    "json_tools_fpath": "C:\\Users\\leoxd\\AppData\\Roaming\\MetaQuotes\\Terminal\\D0E8209F77C8CF37AD8BF550E51FF075\\MQL5\\Shared Projects\\FullMt5McpByLeo\\mt5_mcp_by_leo\\tools.json"
  },
  "mt5_conn": {
    "host": "127.0.0.1",
    "port": 9999
  },
  "http_lib": {
    "name": "McpMt5Server",
    "version": "1.0.0",
    "host": "127.0.0.1",
    "port": 8080,
    "endpoint": "/"
  },
  "stdio_stdin": {
    "name": "MT5 MCP Server",
    "version": "1.0.0"
  }
}

2. Configure in Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "mt5_mcp_by_leo": {
      "command": "PATH_TO_EXE",
      "args": ["PATH_TO_FILE"
      ]
    }
  }
}

• PATH_TO_FILE: Path to json config file
• PATH_TO_EXE: Path to exe McpServer file

3. Configure MetaTrader 5

In MT5: Tools → Options → Allowed URLs for WebRequest

• Add 127.0.0.1 or host you configured.
• Click Accept
• Enable AutoTrading and DLL imports

4. Open claude desktop

Open Claude Desktop. At that moment, a Python script is running in the background until it establishes a connection with the EA McpServer.ex5.

5. Compile & Attach EA

MetaEditor: Open Src/Mt5Mcp.mq5 → Compile (F5) Or Dowland Mt5Mcp.ex5 of releases (last version).
MT5: Drag Mt5Mcp.ex5 onto your chart and cofigure it, The parameters of the EA, such as port/host, must match the JSON of Claude Desktop

6. Use in Claude

Open a 0.01 lot BUY on EURUSD with SL at 1.0800 and TP at 1.0900
