Get platform leaderboard.
AI agents call get_leaderboard to retrieve information from Basis 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 leaderboard data without modifying, executing code, deleting, or affecting financial state. It is a straightforward data retrieval operation typical of Read category tools. Severity is low because leaderboard data is typically public and non-sensitive, and misuse poses no material risk.
From the tool's definition Tool name 'get_leaderboard' and description 'Get platform leaderboard' indicate a retrieval operation with no side effects. The verb 'Get' and the nature of leaderboards (publicly aggregated rankings) confirm this is a read-only query.
