WHAT IT DOES

What lido_stake_eth does on Lido MCP Server

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

WHY IT NEEDS A POLICY

Why lido_stake_eth needs a policy

This tool moves ETH (a financial asset) into the Lido protocol in exchange for stETH tokens. This constitutes a financial commitment — transferring ETH out of the user's wallet and locking it in a staking contract. Misuse could result in unintended ETH being staked, potentially with slippage, lock-up considerations, or loss of funds if misused at scale, making it a high-severity financial operation.
