v0.1.0

First public release. Read only, stdio only.

Added

• MCP server built on mcp>=2.0.0,<3 and MCPServer, served over stdio by the quotez console
  script or by mcp run src/quotez/server.py through the module level mcp global.
• Eight tools in a fixed registration order: list_symbols, get_quote, get_bars,
  get_bars_range, symbol_info, get_account, list_positions, list_orders. Each one is
  annotated read_only_hint=True, open_world_hint=False and returns a Pydantic model, so the SDK
  derives the output schema and validates every payload before it leaves the server.
• One concrete resource, symbols://list, serving the instrument universe as
  application/json.
• MarketDataSource, the protocol both sources implement, so nothing above it imports
  MetaTrader5.
• ReplaySource, backed by four generated instruments bundled in the package and read through
  importlib.resources. It reads no clock: get_quote derives from the last stored bar, which is
  what makes the README transcript reproducible.
• Mt5Source, reading a live terminal through read only calls only. The extension is imported
  lazily, the connection is opened once in the server lifespan, every timestamp is built UTC aware,
  and get_bars starts at the first closed bar so the newest one it returns is never the bar the
  terminal is still building.
• quotez.aggregate, rolling M1 bars up to M5, M15, M30, H1, H4 and D1 by wall clock buckets,
  dropping incomplete trailing buckets and clearing spread on aggregated bars. It is the replay
  source's roll up; Mt5Source asks the terminal for the timeframe instead, and the two therefore
  differ on D1 and H4 alignment and on spread, as Limitations records.
• quotez.groups, implementing MetaTrader's symbols_get group filter syntax for sources that
  have no terminal.
• Configuration through flags or QUOTEZ_* variables: source, symbol whitelist, bar cap
  (default 1000, ceiling 5000) and log level, all validated at startup.
• Errors split across the two MCP channels: SymbolNotFound and InvalidRequest as ordinary
  exceptions the model can retry from, SourceUnavailable as an MCPError protocol error. A
  bundled data file that is missing, unreadable or not UTF-8 is SourceUnavailable naming the
  file, because no argument the model can send will make it readable.
• examples/agent_session.py, which prints the README transcript from an in-process client, and a
  test asserting the README block matches it byte for byte.
• Continuous integration on Ubuntu 3.11 to 3.13, macOS 3.13, a Windows 3.12 job exercising the
  mt5 extra, a macOS job proving that extra is a no-op off Windows, and an advisory 3.14 job.
  Every version leg runs ruff check, ruff format --check, mypy --strict over src and the
  test suite, so the py.typed marker this package ships is backed by a check rather than by
  intent.
