AI agents call trade_query_asset to retrieve information from TdxQuant MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries account financial data and asset summaries but does not execute trades, modify positions, or move money. It is a read operation.
