What appendToGoogleDoc does on Ultimate Google Docs & Drive MCP Server

WHY IT NEEDS A POLICY

Why appendToGoogleDoc needs a policy

This tool modifies a Google Document by appending text—a classic Write operation. While it changes data, the modification is reversible (appended text can be deleted). It does not execute arbitrary code, delete data irreversibly, or move money. Severity is medium because misuse could modify important documents, but the effect is localized to a single document and can be undone.

From the tool's definition Tool name 'appendToGoogleDoc' and description 'Appends text to the very end of a specific Google Document' explicitly indicates modification of document content. This is a reversible write operation that adds content without deletion or destruction.
