## Facts

- Tool: `list_ha_groups`
- Server: Proxmox MCP Server (`gethosthewalrus/proxmox-mcp`) — https://policylayer.com/tools/gethosthewalrus-proxmox-mcp.md
- Homepage: https://github.com/GethosTheWalrus/proxmox-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why list_ha_groups is rated Low

This tool queries and returns data about HA group configurations (which nodes can run HA resources) with no side effects. It performs information retrieval only, fitting squarely into the Read category. The severity is low because misuse would only expose configuration information, not disrupt infrastructure or cause data loss.

From the tool's own definition: "Tool name 'list_ha_groups' and description 'List HA groups' indicate a read operation that retrieves information about high availability groups without modifying infrastructure."

## Use case

AI agents call list_ha_groups 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": {
    "list_ha_groups": {}
  }
}
```
