WHAT IT DOES

What insertLocalImage does on Google Workspace MCP Server

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

WHY IT NEEDS A POLICY

Why insertLocalImage needs a policy

This tool creates new data (uploads an image file) and modifies an existing document (inserts the image). These are reversible write operations—the image and insertion can be deleted. It does not execute arbitrary code, delete data irreversibly, or handle financial transactions. The medium severity reflects that misuse could clutter a user's Drive and documents, but the impact is limited in scope and easily remedied.

From the tool's definition Tool description states it 'Uploads a local image file to Google Drive' and 'inserts it into a Google Document,' which are create/write operations that modify the document and add data to Drive.
