AI agents call get_broker_rate_limit_cap to retrieve information from Bybit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about the Bybit broker's rate limiting configuration. It is a read-only query with no side effects, data modifications, code execution, or financial impact. The low severity reflects that misuse would only expose rate limit information, which is non-sensitive operational data.
From the tool's definition Tool name 'get_broker_rate_limit_cap' and description 'Get broker rate limit cap' indicate a retrieval operation that queries information about rate limits without modifying, executing, or affecting any account state or financial transactions.
