insert_section_break · Google MCP: Risk & Policy

WHAT IT DOES

What insert_section_break does on Google

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

WHY IT NEEDS A POLICY

Why insert_section_break needs a policy

Inserting a section break modifies the structure and content of a Google Doc document. This is a reversible write operation (the break can be removed). The blast radius is limited to formatting/structure of a single document and does not delete data or execute arbitrary code, so it does not qualify as Destructive or Execute.

From the tool's definition Tool description states "Insert a section break in a Google Doc" — a direct modification operation. Server description confirms "Google Docs (insert, replace, append)" as core write capabilities.
