## Why news.hn-item is rated Low

This tool queries public data from Hacker News and returns information about a specific item. It is a read-only operation that retrieves existing data without modifying, deleting, executing code, or incurring financial obligations. The blast radius of misuse is minimal—an agent could only retrieve publicly available information.

From the tool's own definition: "Tool name 'news.hn-item' and description 'Fetch a specific Hacker News item by numeric ID' indicate a retrieval operation with no side effects."

## Use case

AI agents call news.hn-item to retrieve information from 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 Mcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "news.hn-item": {}
  }
}
```
