## Why zernio_get_reddit_subreddits is rated Low

This is a straightforward read operation that queries and returns data (available subreddits) for an authenticated account. It has no capability to modify, delete, or execute actions. The data retrieved is informational and needed for other operations. The blast radius of misuse is minimal — an attacker could enumerate which subreddits are available but cannot post, delete, or cause harm with this tool alone.

From the tool's own definition: "Tool name contains 'get' and description states 'Get subreddits available' — retrieves a list of accessible subreddits with no modification or side effects."

## Use case

AI agents call zernio_get_reddit_subreddits to retrieve information from Zernio 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 Zernio:

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