get_order_book
AI agents call get_order_book to retrieve information from Aster Info without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves order book data from the Aster DEX without side effects. It queries market data passively. The empty description is partially mitigated by context from sibling tools and the server's stated purpose (read-only market data access). No financial transactions, state modifications, code execution, or destructive operations are involved.
From the tool's definition Tool name 'get_order_book' and sibling tools (get_aggregated_trades, get_kline, get_latest_price, get_order_book_ticker, get_recent_trades) are all read-only market data queries.
