## Why weatherTool is rated Low

This tool retrieves weather information for display purposes. It has no side effects, does not execute code or commands, does not modify data, and does not involve financial transactions or destructive operations. It is a straightforward read operation that fetches data from a weather service and presents it to the user.

From the tool's own definition: "Tool name 'weatherTool' with description 'use this tool to display weather' indicates a query operation that retrieves and presents weather data without modifying, executing operations, or affecting external systems."

## Use case

AI agents call weatherTool to retrieve information from Genkit MCP 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 Genkit MCP:

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