Implementation Reference
- Python handler function for the 'cancel_all_orders' tool. It calls the HyperliquidClient's cancel_all_orders method and returns a formatted success or error response.
async def handle_cancel_all_orders(client: HyperliquidClient, args: Dict[str, Any]) -> Dict[str, Any]: """Handle cancel all orders request.""" result = await client.cancel_all_orders() if not result.success: raise ValueError(f"Failed to cancel all orders: {result.error}") return { "content": [ TextContent( type="text", text=f"All orders cancelled successfully!\n\n{json.dumps(result.data, indent=2)}", ) ] } - hyperliquid_mcp_server/tools/trading.py:126-134 (registration)Python tool registration for 'cancel_all_orders' including schema (empty input) and description.
cancel_all_orders_tool = Tool( name="cancel_all_orders", description="Cancel all open orders", inputSchema={ "type": "object", "properties": {}, "required": [], }, ) - Core helper method in HyperliquidClient that performs the API call to cancel all orders using 'cancelByCloid' with empty cancels list.
