WHAT IT DOES

What GOOGLESUPER_FETCH_EMAILS does on Google Super

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

Parameters from the server's own tool schema.

RISK

Why GOOGLESUPER_FETCH_EMAILS is rated Low

This tool retrieves email data from Gmail without creating, modifying, or deleting messages. While email content may be sensitive (moderate severity), the action itself is a straightforward read operation. Severity is medium rather than low because emails often contain confidential information; if an AI agent with this tool is compromised or misdirected, it could exfiltrate sensitive user data.

From the tool's definition Tool name and description indicate it 'Fetches a list of email messages' with 'filtering, pagination, and optional full content retrieval' — core read operations that retrieve but do not modify data.
