## Why station_board_departures is rated Low

This is a straightforward data retrieval tool that queries and returns public transportation information. It performs no writes, deletions, code execution, or financial transactions. The read-only designation and passive data-retrieval nature confirm the Read category with low severity, as misuse would only expose publicly available transport data without risk of system compromise or resource exhaustion.

From the tool's own definition: "The tool is explicitly described as 'Read-only' and retrieves 'live departures' data without modifying or executing operations."

## Use case

AI agents call station_board_departures to retrieve information from InfraNode 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 InfraNode:

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