    "arguments": {

## Why append_to_sheet is rated Medium

This tool creates or modifies data (appending rows) but does not delete, overwrite irreversibly, execute arbitrary code, or move money. It is reversible—appended rows can be edited or removed. The 'write-tier' approval structure confirms it is a Write-category operation. Severity is medium because misuse could corrupt business data or spreadsheets, but the operation is bounded to a single sheet and is undoable.

From the tool's own definition: "Tool name 'append_to_sheet' and description 'Append rows to a Google Spreadsheet' indicate creation/modification of data in a spreadsheet. The approval tier notation confirms reversible write operations (rows can be deleted/modified later)."

## Use case

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