## Why get_cards_by_list_id is rated Low

This tool retrieves/queries card data from a Trello list. It performs a read-only operation with no ability to create, modify, delete, or execute operations. The blast radius of misuse is minimal—an agent could only retrieve information that likely has limited sensitivity in a typical Trello board context.

From the tool's own definition: "Tool name 'get_cards_by_list_id' and description 'Fetch cards from a specific Trello list' indicate data retrieval with no modification or side effects."

## Use case

AI agents call get_cards_by_list_id to retrieve information from Trello without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Trello:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_cards_by_list_id": {}
  }
}
```
