create_presentation · Gg MCP: Risk & Policy

WHAT IT DOES

What create_presentation does on Gg

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

WHY IT NEEDS A POLICY

Why create_presentation needs a policy

The tool creates a new presentation document, which is a reversible write operation. It does not execute arbitrary code, delete data, move money, or trigger destructive actions. The severity is medium because creating presentations could consume storage quotas or be used to clutter a user's workspace, but the effect is easily reversible by deletion.

From the tool's definition Tool name 'create_presentation' and description 'Create a new Google Slides presentation' indicate creation of a new resource in Google Workspace.
