Delete a sandbox project and all its inboxes
AI agents call delete-sandbox-project to permanently remove resources in Mcp Mailtrap — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a sandbox project and all associated inboxes, which is an irreversible deletion operation. The description explicitly uses 'delete' and indicates cascading removal of related resources. While limited to sandbox environments (lower blast radius than production), the irreversible nature of deletion classifies it as Destructive rather than Write.
