• src/mcp_paradex/tools/orders.py:80-135 (handler)

  The primary handler function for the 'paradex_create_order' tool. It constructs an Order object from parameters, submits it using the Paradex client, and returns the resulting OrderState.

Example use cases: - Setting limit orders at key support/resistance levels - Placing stop-limit orders to manage risk on existing positions - Executing market orders for immediate entry or exit - Creating reduce-only orders to ensure you don't flip position direction Succesful response indicates that orders were queued for execution.

  Enum types (OrderTypeEnum, InstructionEnum, OrderSideEnum) used for input parameter validation in the paradex_create_order handler.
  # Define allowed order types OrderTypeEnum = Literal[ "MARKET", "LIMIT", "STOP_LIMIT", "STOP_MARKET", "TAKE_PROFIT_LIMIT", "TAKE_PROFIT_MARKET", "STOP_LOSS_MARKET", "STOP_LOSS_LIMIT", ] # Define allowed instruction types InstructionEnum = Literal["GTC", "IOC", "POST_ONLY"] OrderSideEnum = Literal["BUY", "SELL"]

  Helper function that provides the authenticated ParadexApiClient instance used by the handler to submit orders.
  async def get_authenticated_paradex_client() -> ParadexApiClient: """ Get or initialize the authenticated Paradex client. Returns: Paradex: The initialized Paradex client. Raises: ValueError: If the required configuration is not set. """ client = await get_paradex_client() if client.account is None: raise ValueError("Paradex client is not authenticated") return client
• src/mcp_paradex/tools/orders.py:80-80 (registration)

  The @server.tool decorator registers the create_order function as the MCP tool named 'paradex_create_order'.
