## Why add_columns is rated Medium

This tool creates new columns in a Google Sheets spreadsheet. This is a Write operation because it modifies data structures reversibly—columns can be deleted or reorganized later. The operation does not delete data irreversibly (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or trigger external operations (Execute).

From the tool's own definition: "Tool name 'add_columns' and description 'Add columns to a sheet in a google sheets spreadsheet' indicate creation of new spreadsheet columns, which is a reversible data structure modification."

## Use case

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