namewhisper/ens-tools Financial Risk 5/5

AI agents use bulk_transfer_ens_names to initiate financial transactions through Name Whisper. Financial operations involve real money and are irreversible once processed. Intercept blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.

bulk_transfer_ens_names moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. Intercept blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.

Financial tools involve real money. Block by default and require explicit human approval before enabling.

What does the bulk_transfer_ens_names tool do? +

Transfer multiple ENS names in a single transaction via Multicall3 — bulk send. Much cheaper and faster than transferring names one at a time. Supports up to 20 names per batch. Automatically detects whether each name is wrapped (NameWrapper/ERC-1155) or unwrapped (BaseRegistrar/ERC-721) and builds the correct transfer call for each. All names can go to the same recipient or to different recipients — specify a toAddress per name. Requirements: - The fromAddress must currently own ALL names in the batch - All addresses must be valid Ethereum addresses - Names must be registered (not expired) WARNING: This transfers FULL ownership of every name. Recipients gain complete control. Resolver records (avatar, addresses, etc.) are NOT affected by transfer — they stay on each name. After transfer, consider using bulk_set_records to update ETH address records on the transferred names.. It is categorised as a Financial tool in the Name Whisper MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
