AI agents call updown_get_user_bet 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 existing bet information for a user on a prediction market round. It reads state without modifying, creating, or deleting anything. The return value (amount=0 means no bet placed) confirms it is purely informational. This is a Read operation with low severity since it only exposes user's own betting data.
