## Why set_card_labels is rated Medium

This tool modifies card labels on a Trello card, which is a write operation that changes existing data. It is reversible (labels can be changed again), so it does not qualify as Destructive. While it alters card state, the impact is limited to label metadata on a single card, making it Write rather than Execute.

From the tool's own definition: "Tool description states 'Set all labels on a card, replacing any existing labels' - this modifies card metadata by replacing existing labels with new ones, a reversible change operation."

## Use case

AI agents use set_card_labels 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.
