Implementation Reference

• src/mcp_paradex/tools/orders.py:189-189 (registration)

  Decorator that registers the get_order_status function as the MCP tool named 'paradex_order_status'.
  @server.tool(name="paradex_order_status")
• src/mcp_paradex/tools/orders.py:190-228 (handler)

  The core handler function that implements the paradex_order_status tool logic. It authenticates the Paradex client, fetches the order by ID or client ID, validates the response using OrderState, and returns a standardized dictionary with schema and results.
  async def get_order_status( order_id: Annotated[str, Field(description="Order identifier.")], client_id: Annotated[str, Field(description="Client-specified order ID.")], ctx: Context = None, ) -> dict: """ Check the detailed status of a specific order for execution monitoring. Use this tool when you need to: - Confirm if a particular order was accepted and is active - Check if an order has been filled, partially filled, or canceled - Get execution details for a specific order - Diagnose issues with order placement - Track the status of important orders individually Order status tracking is essential for verifying execution status and troubleshooting any issues with specific orders. Example use cases: - Checking if a recently placed limit order is active in the book - Verifying fill details of a specific order - Determining why an order might have been rejected - Confirming cancellation status of an order you attempted to cancel - Getting execution timestamps for order lifecycle analysis """ client = await get_authenticated_paradex_client() if order_id: response = client.fetch_order(order_id) elif client_id: response = client.fetch_order_by_client_id(client_id) else: raise Exception("Either order_id or client_id must be provided.") order: OrderState = OrderState.model_validate(response) result = { "description": OrderState.__doc__.strip() if OrderState.__doc__ else None, "fields": OrderState.model_json_schema(), "results": order, } return result

  Utility function that provides the authenticated ParadexApiClient instance used by the tool handler to make API calls like fetch_order.

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
