Get K-line (candlestick) data
AI agents call get_kline to retrieve information from Bybit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that retrieves market data. It has no capability to modify accounts, execute trades, delete data, or move funds. The blast radius of misuse is minimal—returning incorrect or stale price data could affect trading decisions, but the tool itself cannot cause direct harm. This is a foundational market data query typical of financial APIs.
