WHAT IT DOES

What cross_vm_transfer does on Tenzro Ledger MCP

AI agents use cross_vm_transfer 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 cross_vm_transfer is rated Critical

This tool directly moves cryptocurrency or tokens between virtual machines (likely blockchains), which constitutes a financial transaction. The 'atomic' nature indicates it cannot be partially reversed. An AI agent misusing this tool could transfer significant assets to unintended addresses or drain wallets, making this a critical-severity financial risk.

From the tool's definition 'cross_vm_transfer' performs 'atomic cross-VM token transfer' — this moves tokens/value across blockchain virtual machines, which is a financial operation that commits monetary obligations and transfers assets.
