Mt5 Mcp By Leo

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).
• EXE from releases
• EX5 Library McpServerByLeo pucharse in: TheBotPlace - McpServerByLeo When you purchase the library, you should already have an account on TheBotPlace. This account will have an ID, which you will put in the .json file of your MCP IA (YOUR_TBP_ID).

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. Downland

Download the latest .exe and .ex5 files from the repo releases....

2. Create a config json

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

{
  "general": {
    "type_reg": "stdio_stdin",
    "json_tools_fpath": "JSON_TOOL_PATH"
  },
  "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"
  }
}

• JSON_TOOL_PATH: Path to the tools configuration json (you can download the json from the mt5_mcp_by_leo folder and place it in documents for example and put the path to said file here...) Or if you have the repository cloned, you can use the path to tools.json

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", "YOUR_TBP_ID", "YOUR_MT5_ACCOUNT_LOGIN_ID" 
      ]
    }
  }
}

• PATH_TO_EXE: Path to exe McpServer file
• PATH_TO_FILE: Path to json config file
• YOUR_TBP_ID: Your The Bot Place user ID
• YOUR_MT5_ACCOUNT_LOGIN_ID: ACCOUNT_LOGGIN of your mt5 account where Mt5Mcp EA is running

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

Run Runner.ex5 in any chart.. (dowland from releases)
Then:
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
