## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "nfs_share_get",
    "arguments": {}

## Why nfs_share_get is rated Low

This tool retrieves configuration or details of an existing NFS share identified by its ID. It performs a query/get operation typical of read-only access. There is no indication of modification, deletion, execution, or financial impact. The low severity reflects minimal blast radius if misused—an agent would only retrieve data about NFS share configurations without ability to alter system state or cause harm.

From the tool's own definition: "Tool name 'nfs_share_get' and description 'Get an NFS share by ID' indicate a retrieval operation with no side effects."

## Use case

AI agents call nfs_share_get to retrieve information from Truenas 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 Truenas:

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