Get holdings for a given nickname
AI agents call get_holdings to retrieve information from QuantPlay 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 account holdings information—a read-only query operation with no side effects. While it accesses financial data (which could be sensitive), it does not move money, execute trades, or modify any state. The risk is low because misuse would only expose information the user already has access to, not cause financial loss or irreversible changes.
From the tool's definition Tool name 'get_holdings' and description 'Get holdings for a given nickname' indicate a retrieval operation that queries existing trading data without modifying or executing transactions.
