WHAT IT DOES

What get_unread_count does on AirMCP

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

RISK

Why get_unread_count is rated Low

This tool queries email metadata (unread count) without modifying, deleting, or executing any operations. It is a straightforward data retrieval operation with minimal security impact. The blast radius of misuse is very low—an agent could learn how many unread messages exist, but cannot access message content, delete messages, send emails, or perform any destructive actions.

From the tool's definition Tool name is 'get_unread_count' and description states 'Get unread message count across all mailboxes.' The verb 'Get' and action of retrieving a count are read-only operations with no side effects.
