Staking Stake S O L
staking_stakeSOLStake native SOL to a validator. Creates a stake account and delegates. SAP MCP context: Protocol staking; operation class write. Use for SOL and liquid staking flows. Confirm validator or provider, amount, lockup/unstake terms, and account ownership before writes. Use SAP staking tools for SAP protocol stake accounts; use AgentKit staking tools for external staking protocols.
SAP MCP execution guidance: Intent: SAP MCP tool 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.
