WHAT IT DOES

What exchange_token does on Tenzro Ledger MCP

AI agents use exchange_token to commit financial operations through Tenzro Ledger MCP, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why exchange_token is rated Critical

The name 'exchange_token' strongly implies swapping or converting tokens/currencies, which is a financial operation. The server context (wallet, payments, staking, bridges) reinforces this interpretation. Token exchanges can result in irreversible financial transactions. Description is empty, which lowers confidence slightly, but the server context and tool name together strongly suggest a financial operation.

From the tool's definition Tool name 'exchange_token' on a server described as handling 'wallet, identity, payments, inference, staking, bridges, verification, agents' with sibling tools including payments and bridges functionality.
