Returns wallet balance
AI agents call account-balance to retrieve information from Walutomat 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 financial account data but does not modify, spend, or transfer money. It is a read-only operation that queries the current state of a wallet. While the data is financial in nature, the action itself is purely informational with no blast radius if misused by an agent (no funds can be moved or committed). It belongs in the Read category.
From the tool's definition Tool name and description indicate it 'Returns wallet balance' — a query operation with no side effects.
