## What it is
`mt5-mcp` lets an AI agent read your MetaTrader 5 account and place trades
through it, over the Model Context Protocol.
- **12 read-only tools**: account, quotes, positions, orders, history, OHLC
bars, broker-authoritative margin estimates, and native chart screenshots
(Windows). No consent gate.
- **4 mutating tools**: `place_order`, `modify_order`, `cancel_order`,
`close_position`, each behind a preflight + human-consent + idempotency +
audit layer.
- **3 subscribable resources**: live `account://`, `positions://`, and
`quotes://{symbol}` snapshots that push change notifications.
- **2 ready-to-use Claude Code skills** ship in
[`.claude/skills/`](https://github.com/vincentwongso/mt5-trading-mcp/tree/main/.claude/skills):
`mt5-market-data` and `mt5-trading` teach an agent how to read the account and
run the consent flow safely.
Full catalogue and the consent flow: **[docs/tools.md](https://github.com/vincentwongso/mt5-trading-mcp/blob/main/docs/tools.md)**.
## Why mt5-mcp
- **A safety layer, not just an API wrapper.** Every mutating call routes through
preflight checks -> an opt-in human-consent gate (arm it to require approval) ->
idempotency -> an append-only audit log, so you can put a human in the loop on
trades and always keep a replayable record of what the agent did.
- **An honest threat model.** It treats an LLM wired to `place_order` as a live
attack surface and says so plainly - the MCP is explicitly *not* the security
boundary (see [SECURITY.md](https://github.com/vincentwongso/mt5-trading-mcp/blob/main/SECURITY.md)).
- **Verifiable proof, not a mock-up.** The demo above is a real round-trip; the
tickets and balance match MetaTrader 5's own History tab.
- **Local-first.** No cloud, no telemetry; runs beside your agent. Windows-native
or Linux via an all-in-one Docker image (no `rpyc` version-matching).
## Quickstart (Windows, native)
```bash
pip install mt5-trading-mcp
```
1. Launch MetaTrader 5 and log into your broker. Enable **AlgoTrading** (toolbar
button green).
2. Verify the terminal is reachable: `python -m mt5_mcp doctor`: expect
`[INFO] backend: native` and `[PASS]` lines.
3. Run it: `python -m mt5_mcp serve`.
Wire it to OpenClaw in one command (registers the `mcp.servers` entry):
```bash
openclaw mcp set mt5-mcp '{"command":"python","args":["-m","mt5_mcp","serve"]}'
```
## Quickstart (Linux, Docker)
The MT5 terminal + the MCP run headless in an all-in-one image; your agent talks
MCP over HTTP. No host Python, no bridge.
```bash
cp deploy/.env.example deploy/.env # add MT5_LOGIN / MT5_PASSWORD / MT5_SERVER
docker compose -f deploy/docker-compose.yml up -d
```
Log the terminal in once via the KasmVNC web UI at `http://127.0.0.1:3001`
(**File -> Login to Trade Account**; persists across restarts), then point your
agent at `http://127.0.0.1:8765/mcp`. Wire it to OpenClaw in one command:
```bash
openclaw mcp set mt5-mcp '{"url":"http://127.0.0.1:8765/mcp","transport":"streamable-http"}'
```

**[docs/installation.md](https://github.com/vincentwongso/mt5-trading-mcp/blob/main/docs/installation.md)**.
## Chart screenshots (Windows only)
`get_chart_screenshot(symbol, timeframe, annotations?)` returns a PNG of the
native MT5 chart, optionally annotated, so an LLM can read it visually
(candles, support/resistance, patterns). Because the MetaTrader5 Python API
cannot capture charts, this uses a small MQL5 Expert Advisor that runs inside
a GUI terminal and calls `ChartScreenShot()`.
See [Chart annotations](docs/tools.md#chart-annotations) for marking up
support/resistance lines, trendlines and notes before capture.
Setup (one time):
1. Install and attach the `AgentScreenshot` EA - see `mql5/README.md`.
2. Optionally set a template so your indicators/drawings appear in the shot:
`[screenshot]` `template = "agent.tpl"` in your config, or leave it unset
for the default chart.
Config knobs (`[screenshot]` section): `width` (default 1600), `height`
(default 900), `template` (default none), `timeout_s` (default 10).
Not available on the headless Linux/Docker deployment: it needs a GUI
terminal. Off Windows the tool returns `SCREENSHOT_NOT_SUPPORTED`.
## For AI agents
**If you've been handed this repository to install and run, follow the runbook
in [docs/agents.md](https://github.com/vincentwongso/mt5-trading-mcp/blob/main/docs/agents.md).**
It covers platform detection, install, verification, registering the server, and
the hard safety rules for trades - read it before calling any mutating tool.

## Safety
`mt5-mcp` is **not** the security boundary, the broker's MT5 server enforces
the hard limits (margin, max-lot, symbol permissions). Pre-flight checks in the
policy engine are UX guardrails to catch agent mistakes early, not security
controls.
The human-consent gate is **opt-in and off by default**: `auto_approve_notional`
defaults to `0`, so mutating calls auto-execute (full-open) - intended for trusted
or unattended agents. **Arm the gate by setting `auto_approve_notional` > 0**:
orders/closes whose notional is at or above it then return an `ApprovalPreview`
you must confirm, and modifying a stop to widen or remove it also requires
approval. The pre-flight limits (`max_*`) and symbol allow/deny lists are likewise
opt-in (`0` / empty = off). Every mutating call is recorded in an append-only audit
JSONL log regardless. For vulnerability disclosure, see
[SECURITY.md](https://github.com/vincentwongso/mt5-trading-mcp/blob/main/SECURITY.md).
## Architecture
`mt5-mcp` wraps the MetaTrader 5 Python library behind a FastMCP server. A single `MT5Client` (`src/mt5_mcp/adapter/`) owns the terminal connection, broker-timezone inference, and type conversions; everything else sits on top of it. The Pydantic models in `src/mt5_mcp/types.py` / `src/mt5_mcp/config.py` are the source of truth for the data and config schemas.
