## Why nrel_alt_fuel_stations is rated Low

This tool performs a location-based search/lookup to retrieve information about alternative fuel stations. It has no side effects beyond data retrieval. While used by route planning and fleet operators, the tool itself only returns informational results to support decision-making; it does not execute commands, modify any systems, or commit financial transactions.

From the tool's own definition: "Tool description states it 'Find[s] alternative fuel stations near a location' - a query operation that retrieves data about fuel station locations and types. No creation, modification, deletion, code execution, or financial operations are described."

## Use case

AI agents call nrel_alt_fuel_stations to retrieve information from Livedatalink 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 Livedatalink:

```json
