WHAT IT DOES

What wallet_listTokens does on Bitcoin SV MCP Server

AI agents call wallet_listTokens 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_listTokens is rated Low

This tool performs a read-only operation to enumerate token holdings in a wallet. It retrieves and displays information about BSV21 tokens but does not create, modify, delete, or execute any state-changing operations. The blast radius is minimal since it only exposes wallet token inventory data without ability to transfer, burn, or manipulate tokens.

From the tool's definition Tool name 'wallet_listTokens' and description 'List BSV21 token outputs in the wallet' indicate a retrieval operation that queries existing token data without modification, deletion, or execution of external commands.
