## Why create_cards is rated Medium

Creating cards is a Write operation—it creates new data in Trello that can be modified or deleted later. While not destructive, bulk card creation could clutter boards and require cleanup, posing a medium severity risk if an agent misuses parameters. Confidence is slightly reduced due to the tool's empty description, but the name and context from sibling tools and server capabilities are clear.

From the tool's own definition: "Tool name 'create_cards' and server description stating 'supports full CRUD operations' and 'create_card' as a sibling tool. The tool creates new cards in Trello, which are reversible modifications to board state."

## Use case

AI agents use create_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.

## Recommended policy (PolicyLayer)
