WHAT IT DOES

What satoshi_activity_by_address does on Maestro MCP Server

Why satoshi_activity_by_address needs a policy

This tool queries and retrieves blockchain transaction history for an address—a purely informational, read-only operation with no side effects. While it provides financial context about blockchain activity, it does not move funds, execute code, or modify data. The risk is low because misuse would only expose historical blockchain data that is already public on the Bitcoin network.

From the tool's definition Tool returns historical transaction data for a given address. Key indicators: 'Returns all transactions', 'allowing insight', 'historical views'.
