View full transaction history — deposits, withdrawals, service charges, casino bets.
AI agents call wallet_history to retrieve information from Purple Flea Casino without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries historical financial transaction records without side effects. While it provides visibility into wallet activity (deposits, withdrawals, bets), viewing transaction history is a standard read operation with no capacity to move funds, alter balances, or execute trades. The blast radius of misuse is minimal—an AI agent could only enumerate or analyze past transactions, not commit financial harm.
From the tool's definition Tool name 'wallet_history' and description 'View full transaction history' indicate a read-only operation that retrieves and displays past transactions without creating, modifying, or deleting data.
