WHAT IT DOES

What prepare_rocketpool_stake does on VaultPilot MCP

AI agents use prepare_rocketpool_stake to commit financial operations through VaultPilot MCP, usually the final step of a payment, billing, or trading workflow. A call moves real money.

Parameter	Type	Required	Description
`wallet`	string	Yes
`amountEth`	string	Yes	Human-readable ETH amount to stake into Rocket Pool (mints rETH), NOT raw wei. Example: "0.5" for 0.5 ETH. Protocol minimum is ~0.01 ETH; the deposit pool also

Parameters from the server's own tool schema.

RISK

Why prepare_rocketpool_stake is rated Critical

This tool constructs a financial transaction that stakes ETH into Rocket Pool, committing funds to a DeFi protocol and minting rETH tokens. Even though it produces an unsigned transaction (requiring a separate signing step), it is directly preparing a financial commitment of real ETH assets on Ethereum mainnet. The Financial category applies because it moves crypto assets and commits them to a staking protocol.

From the tool's definition Build an unsigned Rocket Pool stake transaction (RocketDepositPool.deposit() payable, mints rETH at the current exchange rate)
