Parameters from the server's own tool schema.
This tool retrieves and enumerates domains from the Resend service. It performs a read-only query operation with no capacity to create, modify, delete, or execute actions. The blast radius of misuse is minimal—an agent could only discover what domains exist in the account, which is low-risk information exposure.
From the tool's definition Tool name contains 'list' and description states 'List domains configured in Resend.' The verb 'list' is a query operation that retrieves information without modification or side effects.
