WHAT IT DOES

What wallet_getBalance does on Bitcoin SV MCP Server

AI agents call wallet_getBalance to retrieve information from Bitcoin SV MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why wallet_getBalance is rated Low

This tool performs a read-only operation—querying the balance of a wallet on the BSV blockchain. It retrieves data without side effects, does not execute transactions, does not create or modify data, and does not delete anything. The operation is informational only. Severity is low because misuse would only expose wallet balance information, not enable unauthorized fund transfers or destructive actions.

From the tool's definition Tool name 'wallet_getBalance' and description 'Retrieves the current BSV balance for the wallet' indicate a query operation that reads blockchain state without modification or execution of transactions.
