FAQ

Questions about spl-token_transferSol

What does the spl-token_transferSol tool do? +

Transfer native SOL between wallets via SystemProgram.transfer. SAP MCP context: Protocol spl-token; operation class write. Use for SPL token deploy, mint, transfer, burn, freeze, thaw, and authority management. Confirm mint, decimals, authority, recipient, and amount before writes. Use token tools alongside SAP payments and settlement tools only when token operations are part of the agent service lifecycle. SAP MCP execution guidance: Intent: local-signer write workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. Routing: hosted accountless write is blocked; do not call this as a paid hosted write and no x402 payment should be charged. Use the local sap_payments bridge or a hosted unsigned builder when user signing is required. Signer boundary: user-controlled local profile or external signer; OOBE hosted MCP remains non-custodial. It is categorised as a Financial tool in the Sap MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
