WHAT IT DOES

What storage_open_deal does on Tenzro Ledger MCP

AI agents use storage_open_deal 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 storage_open_deal is rated Critical

Opening a storage deal on a ledger/payments platform constitutes a financial commitment. The term 'deal' in the context of a ledger MCP server (which explicitly includes payments, staking, and bridges) strongly implies a contractual or financial obligation being created. This is more severe than a simple Write operation because it commits financial resources.

From the tool's definition 'Open a streaming storage deal' — initiates a financial deal/contract for storage services, implying a financial commitment or obligation
