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

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

## Why get_storage_rrddata is rated Low

This tool queries and retrieves pre-existing monitoring data about storage pool usage patterns over time. It is purely informational with no capability to modify, execute operations, or delete data. The blast radius of misuse is minimal — an attacker could only gain visibility into storage usage trends, which does not compromise confidentiality of sensitive data, integrity, or availability of infrastructure.

From the tool's own definition: "Tool name contains 'get_' prefix and description states 'Get RRD statistics' — retrieves historical usage data without modification. RRD (Round Robin Database) is a time-series database used for monitoring/graphing metrics. No side effects or state changes."

## Use case

AI agents call get_storage_rrddata to retrieve information from Proxmox MCP Server 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 Proxmox MCP Server:

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