Get all open orders, optionally filtered by coin.
AI agents call get_open_orders to retrieve information from Hyperliquid MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing order data without modifying, deleting, or executing any trades. It is purely informational, similar to other Read-category tools on the server like 'get_candles', 'get_funding_rates', and 'get_historical_orders'. The lack of action verbs (create, delete, execute, transfer) and the explicit 'get' pattern confirm a read-only classification.
From the tool's definition Tool name 'get_open_orders' and description 'Get all open orders, optionally filtered by coin' indicate a retrieval operation with no side effects.
