WHAT IT DOES

What move-cards does on Trello MCP Server

AI agents use move-cards to create or update resources in Trello MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Trello MCP Server environment.

WHY IT NEEDS A POLICY

Why move-cards needs a policy

Move-cards modifies card state (position/list assignment) but does not delete data or execute arbitrary code. It is reversible and represents a Write operation. Severity is medium because bulk operations ('move-cards' implies multiple) across a workspace could disrupt team workflows if misapplied, but the action is not destructive or financial.

From the tool's definition Tool name 'move-cards' and sibling tools include 'create-card', 'archive-card', 'add-comment', 'add-label'—all Write operations. Moving cards modifies their list/position state reversibly within Trello boards.
