Fetch inbox messages. Returns messages across all current and historical email addresses. Supports full-text search.
AI agents call keyid_get_inbox to retrieve information from KeyID Agent Kit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries email messages without creating, modifying, or deleting data. However, the severity is elevated to 'medium' rather than 'low' because email inboxes often contain sensitive personal, financial, and private information—misuse could expose confidential communications, credentials, or personal details.
From the tool's definition Tool name 'keyid_get_inbox' and description 'Fetch inbox messages' with 'full-text search' support indicate data retrieval with no modification or deletion.
