### Description (declared)

# MetaTrader 5 MCP Server

MetaTrader 5 integration for Model Context Protocol (MCP). Provides read-only access to MT5 market data through Python commands, built on the [FastMCP v3](https://gofastmcp.com) framework. Optionally encodes responses in [TOON](https://github.com/toon-format/toon) for LLM token savings.

## ⚡ What's New in v0.6.3

- **Production packaging fix** – The wheel now depends on `fastmcp-slim[server]>=3.4,<4` directly instead of the empty `fastmcp` meta-package. This bypasses a [known FastMCP v3 packaging hazard](https://github.com/PrefectHQ/fastmcp/issues/4207) that could leave the `fastmcp` namespace empty after a pip upgrade. Also: `MetaTrader5` is now platform-gated to Windows, so the wheel installs cleanly on Linux/macOS too (with a runtime guard that explains why the tools can't run there).

## ⚡ What's New in v0.6.2

- **TOON output encoding** – tabular tool responses (50-bar `copy_rates_from_pos`, etc.) are automatically encoded in [TOON](https://github.com/toon-format/toon) format when it would save ≥10 % of tokens over compact JSON. The LLM never has to ask for it; the server detects the shape. Install with `pip install "mt5-mcp[toon]"`.

## ⚡ What's New in v0.6.0

- **FastMCP v3** – Pinned `fastmcp>=3.0,<4`. The framework derives JSON schemas from your Python type annotations; no more string-encoded JSON parameters.
- **No more Gradio** – the experimental `gradio_server.py` and the `[ui]` extra are gone. This release is FastMCP-only.
- **Three transports in one process** – `stdio` for Claude Desktop / VS Code, Streamable HTTP on `/mcp`, and legacy SSE. `--transport all` runs them concurrently.
- **ASGI deployment** – `--asgi` emits an `app:app` for `uvicorn`, `gunicorn`, or `hypercorn`.
- **First-class middleware** – rate limiting (per-IP sliding window) and request logging live in FastMCP middleware, not in function bodies.
- **CI** – `lint` (ruff) + cross-platform `pytest` jobs on every push.
- **61 tests** – unit + integration via `…
