RISK

Why get_base_storage is rated Low

This tool queries blockchain storage state without modifying, executing code, or triggering external operations. It is a straightforward read operation against the Base blockchain. The blast radius of misuse is minimal—an AI agent could at worst enumerate or exfiltrate public blockchain data already visible on-chain. No reversible writes, destructive actions, or financial operations are possible.

From the tool's definition Tool name is 'get_base_storage' and description states 'Read one storage slot on Base via eth_getStorageAt'. The verb 'Read' and the use of eth_getStorageAt (a read-only RPC method) confirm this is a data retrieval operation with no side effects.
