WHAT IT DOES

What archive_email does on Enhanced MCP Server

AI agents use archive_email to create or update resources in Enhanced MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced MCP Server environment.

WHY IT NEEDS A POLICY

Why archive_email needs a policy

Archiving an email modifies the email's state/location within Gmail but does not permanently delete it—the action is reversible (emails can be unarchived). This makes it a Write operation rather than Destructive. The severity is medium because misuse could hide important communications from view, potentially causing operational disruption, but the effect is not data loss or financial impact.

From the tool's definition Tool name is 'archive_email' and description states 'Archive an email', which is a state modification operation on email data (moving from inbox to archive).
