WHAT IT DOES

What batch-update-emails does on MCP Google Workspace

AI agents use batch-update-emails to create or update resources in MCP Google Workspace, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Google Workspace environment.

RISK

Why batch-update-emails is rated Medium

This tool creates or modifies email data reversibly (updating labels and status are non-destructive operations that can be undone). While it affects many records at scale (up to 1000), the modifications are reversible, preventing it from being classified as Destructive.

From the tool's definition Tool description states 'Modify multiple emails labels/status' and 'bulk operations on many emails' with capacity for up to 1000 IDs per request. The word 'Modify' indicates data mutation rather than retrieval.
