transfer_sui

Transfer SUI from a managed wallet to a recipient address. Amount is in SUI (not MIST).

Part of the Sui MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents use transfer_sui to initiate financial transactions through Sui. Financial operations involve real money and are irreversible once processed. Intercept blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.

// WHY ENFORCE A POLICY ON TRANSFER_SUI

transfer_sui moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. Intercept blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.

// RECOMMENDED POLICY

Financial tools involve real money. Block by default and require explicit human approval before enabling.
