WHAT IT DOES

What email_list_mailboxes does on ScopeGate

AI agents call email_list_mailboxes to retrieve information from ScopeGate without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why email_list_mailboxes is rated Low

This tool performs a read-only operation that lists available email folders. It retrieves structural information about the Gmail account's mailbox hierarchy but does not modify, delete, or execute any actions. The severity is low because exposure of mailbox folder names alone has minimal direct impact, though it does reveal account structure to potential attackers.

From the tool's definition Tool name 'email_list_mailboxes' and description 'List all email mailboxes/folders' indicates retrieval/querying of mailbox metadata without modification or deletion.
