WHAT IT DOES

What applyTextStyle does on Google Workspace MCP Server

AI agents use applyTextStyle 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 applyTextStyle needs a policy

The tool creates or modifies data (text formatting in a document) in a reversible manner. Formatting changes can be undone, making this a Write operation rather than Destructive. While it affects document appearance, it does not delete data, execute code, or cause irreversible changes.

From the tool's definition Applies character-level formatting (bold, color, font, etc.) to a specific range or found text. This modifies document content by changing text properties.
