## Why list_boards is rated Low

This tool performs a simple query operation that retrieves and displays information about boards accessible to the user. It does not create, modify, delete, or execute any actions—it only reads and returns existing data. Therefore, it falls cleanly into the Read category with low severity since disclosure or misuse would only expose information the user is already authorized to access.

From the tool's own definition: "The tool name is 'list_boards' and the description states it 'List Trello boards the authenticated user can access.' This is a retrieval operation with no side effects."

## Use case

AI agents call list_boards 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": {
    "list_boards": {}
  }
}
```
