insert_image · Google Connections MCP: Risk & Policy

WHAT IT DOES

What insert_image does on Google Connections

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

WHY IT NEEDS A POLICY

Why insert_image needs a policy

Image insertion modifies documents reversibly—images can be deleted or replaced later. This is a Write operation, not Destructive. Severity is medium because while inserting images is non-destructive, it could clutter or deface documents if used maliciously. The empty description lowers confidence slightly, but the tool name and server context provide strong evidence for the Write classification.

From the tool's definition Tool name 'insert_image' combined with server's 'full CRUD operations' capability on Google Docs/Sheets suggests the tool creates or modifies document content by embedding images.
