WHAT IT DOES

What token_balance does on Tenzro Ledger MCP

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

RISK

Why token_balance is rated Low

This tool retrieves financial account information (token balance) but does not move funds, modify state, execute code, or destructively alter data. It is a straightforward read operation that returns data about an address's holdings. The low severity reflects that misuse would only expose existing balance information, not cause financial loss or other harm.

From the tool's definition Tool name 'token_balance' and description 'Get the TNZO token balance for an address' indicate a query/retrieval operation with no side effects.

token_balance Allowed

token_balance is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
