RISK

Why TRELLO_ADD_BOARDS is rated Medium

This tool creates new data (a Trello board) which is a Write operation. While the creation is reversible (unlike Destructive operations), it does modify the state of the Trello workspace by adding a new board. The severity is medium because creating a board is not immediately harmful but could clutter the workspace or be used to create spam/decoy boards if an agent acts maliciously.

From the tool's definition 'Creates a new Trello board' — the tool creates a new resource (a board) that is reversible (boards can be deleted or archived). The description explicitly states the primary action is board creation, a write operation.
