WHAT IT DOES

What mark-as-read does on Meme MCP Server

RISK

Why mark-as-read is rated Medium

This tool modifies email state (read status) in Gmail, which qualifies as a Write operation. It is not Destructive (emails are not deleted), not Financial, and not Execute (no arbitrary code/external operations triggered). Severity is low because the change is trivial and fully reversible; an AI agent misusing this poses minimal risk.

From the tool's definition Tool description states 'Mark emails as read', which modifies email metadata without deletion or financial impact. The action is reversible—emails can be marked unread again.
