Releases

v0.5.0v0.5.0 · 4 Sep 2026Protocol-quality release. The tool surface shrinks from 39 to 27 so the catalogue costs less context per call, and every tool now behaves the way MCP clients expect. Changed (breaking) Consolidated tools — the old names remain as…

v0.4.2v0.4.2 · 4 Sep 2026Bug-fix release. No new tools; several results that were silently wrong are now correct. Fixed Install: pin `mcp>=1.28,<2`. `mcp` 2.x renamed `FastMCP`, so every fresh install of 0.4.1 failed to import. CI: pin the ruff rule set…

v0.4.1v0.4.1 · 4 May 2026Changed `compile`, `syntax_check`, and `smoke_test` now write logs and temporary tester ini files into a hidden `.mt5tmp/` directory next to the source instead of leaking `*.log` and `*.smoke.ini` files into the project root. Override the…

README

mcp-mt5

Model Context Protocol server for the MetaTrader 4/5 build pipeline. Compile MQL sources, deploy compiled EAs, run Strategy Tester, parse reports, tail logs — all driven by an LLM agent without touching the MetaTrader UI.

What this is — and what it isn't

✅ This server	❌ Not this server
MetaTrader dev harness — compile, deploy, backtest, parse	Live trading (orders, positions, quotes)
Wraps `MetaEditor64.exe` / `terminal64.exe` CLI directly	Wraps the `MetaTrader5` Python package
Runs entirely offline against installed terminal	Connects to a broker server
Iterates strategies before they go live	Executes strategies in production

Use case: an LLM agent edits .mq5 source → compiles → deploys → runs Strategy Tester → reads report → adjusts → repeats. No broker login, no human in the loop, no risk of real-money execution.

For runtime trading, pair this with a live-trading MCP — they target different layers and compose well.

Tools

27 tools (plus 16 deprecated aliases until 0.6.0) and 2 resource templates. Every tool carries MCP annotations (read-only / destructive hints), a typed output schema and per-parameter descriptions; failures are reported as tool errors, never as a normal result with an error key.

🔍 Discovery & terminal selection

Tool	Description
`env_info`	Resolved paths, terminal hash, edition, and missing-component issues
`list_terminals`	Every MT4/5 terminal data folder under `%APPDATA%\MetaQuotes\Terminal` with its `origin.txt` install path
`select_terminal`	Switch the active terminal data folder mid-session by origin path, hash, or install dir

🔨 Build & deploy

Tool	Description
`compile`	MetaEditor CLI on a `.mq4`/`.mq5`/`.mqh`. `ok` requires a `Result:` line with 0 errors and a freshly written binary (MetaEditor's exit code is 1 even on success and is ignored). `syntax_only=true` uses `/s` for a fast check without a binary
`compile_and_deploy`	Compile, then copy the fresh `.ex4`/`.ex5` into `Experts/`
`deploy`	Copy a compiled binary into `Experts/` or a `.mqh` into `Include/`, chosen by extension
`smoke_test`	Compile + deploy + 1-day headless backtest + journal scan for runtime errors
`list_experts`	Enumerate `Experts/` (defaults to `.ex5` on MT5, `.ex4` on MT4)

🔎 Source analysis & lint

Tool	Description
`inspect_source`	`input` declarations, `#include` tree with missing files, MetaEditor doc blocks, whole-word symbol search, duplicate magic numbers (`aspects=[...]`)
`analyze_mql`	Structural lint (missing `OnInit`/`OnTick`, unused inputs, hardcoded magic/symbol), MT4-style deprecated calls with MT5 replacements, LOC/function/nesting metrics (`checks=[...]`)
`validate_tester_ini`	Required keys, date format, numeric ranges; cross-checks `[TesterInputs]` against the EA source

✏️ Format & refactor

Tool	Description
`format_mql`	`clang-format` with MQL literals (`D'…'`, `C'…'`) and `input group`/`#property` lines protected. Dry run unless `write=true`; keeps the file's encoding
`rename_symbol`	Whole-word rename across a tree, `dry_run` by default
`extract_function`	Brace-aware extraction of a line range into a helper (inline or into a `.mqh`), `dry_run` by default

📊 Strategy Tester

Tool	Description
`patch_tester_ini`	Update `Section.Key` values in a `tester.ini` in place (encoding preserved)
`gen_tester_inputs`	Build a `[TesterInputs]` block from the EA's inputs, optionally written into an ini
`run_backtest`	Launch `terminal64.exe /config:tester.ini`, wait for `ShutdownTerminal=1`, stream progress notifications, return `report_path`, `report_uri`, tester log and journal notes (`history_synchronized`, `final_balance`, `test_passed`, `start_time_changed`…). Retries once when the tester started before the history download finished
`start_backtest` / `get_backtest` / `cancel_backtest`	Background runs: launch and get a `run_id` immediately, poll status (or list all runs), kill. Runs persist to `.mt5tmp/runs/`
`read_tester_report`	Parse an MT5/MT4 report into a ~50-field `summary`; `response_format="detailed"` adds every trade row. The HTML itself is served as the `mt5://report/{id}` resource
`compare_reports`	Diff two reports key by key with absolute/percent deltas; pass `guards` to get `violations`/`ok`
`read_optimization`	Read a `Tester/cache/.opt` cache using the layout MetaQuotes published: header, optimised inputs, and the top N passes by any criterion over all* passes
`kill_terminal`	Kill terminals launched by this server (`all_instances=true` for every instance)

📝 Logs & snapshots

Tool	Description
`tail_log`	Tail `Files/LiveLog.txt`, the daily Experts log `MQL5/Logs/YYYYMMDD.log`, the terminal Journal `logs/YYYYMMDD.log`, or the newest tester log; optionally parsed into `{ts, source, message}` (both the tab-separated and dated journal formats)
`snapshot_sources` / `list_snapshots`	Freeze source files into a timestamped folder with a `manifest.json`; list them

📡 MCP resources

URI	Description
`mt5://log/{mode}`	Last 500 lines of `livelog`, `journal`, `terminal` or `tester`
`mt5://report/{id}`	Full HTML of a report returned by `read_tester_report` / `get_backtest` (`latest` = newest on disk)

Deprecated aliases (removed in 0.6.0)

The pre-0.5.0 tool names still work in 0.5.x as thin wrappers whose descriptions start with DEPRECATED. Set MCP_MT5_LEGACY_TOOLS=0 to hide them and shrink the tool catalogue to the 27 tools above.

Deprecated name	Use instead
`syntax_check`	`compile(syntax_only=true)`
`deploy_ea`, `install_include`	`deploy`
`extract_inputs`, `resolve_includes`, `extract_doc`, `find_symbol`, `find_magic_collision`	`inspect_source`
`lint_basic`, `check_deprecated`, `code_metrics`	`analyze_mql`
`format_check`	`format_mql` (dry run by default)
`parse_optimization`, `top_passes`	`read_optimization`
`regression_check`	`compare_reports(guards=…)`
`list_backtests`	`get_backtest()` without `run_id`
`mt5://livelog`, `mt5://journal`, `mt5://tester-log`	`mt5://log/{mode}`

Quick start

Install

pip install mcp-mt5

Requires Windows + an installed MetaTrader 4 or 5 terminal.

Register with an MCP client

Most MCP clients accept a JSON entry under mcpServers. The server inherits its configuration from environment variables:

{
  "mcpServers": {
    "mt5": {
      "command": "mcp-mt5",
      "env": {
        "MT5_INSTALL": "C:\\Program Files\\MetaTrader 5"
      }
    }
  }
}

Refer to your client's documentation for the exact config file location.

Verify the install

Once registered, ask your agent to call env_info:

{
  "edition": "mt5",
  "install": "C:\\Program Files\\MetaTrader 5",
  "terminal_hash": "<32-char-hex-hash>",
  "metaeditor": "C:\\Program Files\\MetaTrader 5\\MetaEditor64.exe",
  "experts_dir": "C:\\Users\\<you>\\AppData\\Roaming\\MetaQuotes\\Terminal\\<hash>\\MQL5\\Experts",
  "issues": []
}

An empty issues array means everything is wired up correctly.

Configuration

Resolution priority for the MetaTrader install + data folder:

Explicit env vars (below)
Auto-scan of %APPDATA%\MetaQuotes\Terminal\*\origin.txt for a folder whose origin matches MT5_INSTALL
Portable mode fallback (data colocated with install dir)

Env var	Default	Notes
`MT5_INSTALL`	`C:\Program Files\MetaTrader 5`	Install dir containing `terminal64.exe`
`MT5_DATA`	(auto-detected)	`%APPDATA%\MetaQuotes\Terminal\<hash>`
`MT5_TERMINAL_HASH`	(auto-detected)	32-char folder name
`MT5_EDITION`	`mt5`	Set to `mt4` for MetaTrader 4

Running the server from WSL

The server can run inside WSL and drive the Windows MetaTrader install through WSL interop. The install (/mnt/c/Program Files/MetaTrader 5) and the data folder (scanned under /mnt/*/Users/*/AppData/Roaming/MetaQuotes/Terminal, matched through origin.txt) are auto-detected; MT5_INSTALL / MT5_DATA override them. Paths handed to MetaEditor/terminal are translated with wslpath -w automatically. Interop must be enabled (/etc/wsl.conf [interop] enabled=true, then wsl --shutdown).

MT4 support

Set MT5_EDITION=mt4 and point MT5_INSTALL at your MT4 install. The server switches to metaeditor.exe (32-bit), terminal.exe, and the MQL4/ data tree automatically.

Example workflow

A typical LLM-driven iteration loop:

1. env_info                                          → verify paths
2. compile_and_deploy source="C:\\...\\MyEA.mq5"       → 0 errors, .ex5 deployed ✅
3. patch_tester_ini config="tester.ini" updates={
     "Tester.Symbol": "EURUSD",
     "Tester.FromDate": "2025.01.01",
     "TesterInputs.RiskPct": "1.5"
   }
4. run_backtest config="tester.ini" wait=true
5. read_tester_report path=<report_path from step 4>  → summary.net_profit = 1234.56
                                                       summary.profit_factor = 1.45
6. tail_log mode="tester" lines=200 structured=true  → diagnose journal warnings
7. <edit Signal.mqh based on findings>
8. → loop back to step 2

Development

git clone https://github.com/PHUICMT/mcp-mt5
cd mcp-mt5
pip install -e ".[dev]"
pytest                    # runs the test suite (no MetaTrader needed)
ruff check src tests      # lints

CI runs on Windows for Python 3.10, 3.11, and 3.12 against every push to main. Tagging a release (e.g. v0.2.0) triggers an OIDC publish to PyPI.

Limitations

Windows-only. MetaTrader CLI binaries don't ship for Linux/macOS. Wine ports may work but are untested.
No live broker access. This server intentionally never authenticates to a broker. Use a separate MCP server for runtime trading.
Tester report parsing is best-effort. MetaTrader's HTML output isn't a stable schema; the raw HTML is also returned alongside the parsed structure so you can fall back to text inspection when needed.
Optimisation caches (Tester/cache/*.opt) are parsed with the layout MetaQuotes published in MQL5 Programming for Traders. Files with an unrecognised record layout are reported as such rather than guessed.

Roadmap

All v0.3.x roadmap items shipped in v0.4.0. Future ideas:

Real tree-sitter MQL grammar for extract_function (current implementation is brace-counting + regex)
WebSocket transport for long-lived sessions (currently stdio only)
Linux/Wine port for non-Windows agents
