WHAT IT DOES

What take_mailbox_snapshot does on 20i MCP Server

AI agents use take_mailbox_snapshot to create or update resources in 20i MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 20i MCP Server environment.

RISK

Why take_mailbox_snapshot is rated Medium

This tool creates a backup/snapshot of a mailbox, which is a write operation that generates new data (a snapshot/backup file). It does not delete or overwrite existing data, and it is reversible in the sense that the snapshot can be deleted later. The blast radius is medium since it operates on email data which may be sensitive.
