It performs no write operations, executes no code, deletes nothing, and moves no money. Even in a financial trading context, reading market data poses minimal risk as it cannot directly cause financial harm or unintended trades. The blast radius of misuse is limited to potential information leakage or API rate limiting. From the tool's own definition: "Tool is described as 'Get historical candlestick/OHLC data' which retrieves price data without side effects. The term 'Get' and the purpose for 'technical analysis' indicate pure data retrieval with no modifications to account state, positions, or balances." ## Use case AI agents call get_kline 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. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
