WHAT IT DOES

What queryBrokerAccountInfo does on Bybit MCP Server

AI agents call queryBrokerAccountInfo to retrieve information from Bybit MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why queryBrokerAccountInfo is rated Low

This is a Read operation—it retrieves account information from a broker master account without modifying or executing anything. However, severity is elevated to 'high' rather than 'low' because: (1) the data returned likely includes sensitive financial account details (balances, positions, trading history), and (2) it requires 'exchange broker master account authentication', implying privileged access.

From the tool's definition Tool name is 'queryBrokerAccountInfo' and description states 'query account information'. The verb 'query' combined with 'account information' indicates retrieval/inspection of data with no modification.
