WHAT IT DOES

What validate_clusters does on MCP Proxmox Server

AI agents call validate_clusters to retrieve information from MCP Proxmox Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why validate_clusters is rated Low

Validation/connectivity checks are read-only operations that test reachability without modifying any data or state. The tool queries cluster status to confirm connections, producing no side effects.

RECOMMENDED RULE

The rule that runs validate_clusters safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MCP Proxmox Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For validate_clusters, this is the rule to start with:

validate_clusters Allowed

validate_clusters is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "validate_clusters": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect MCP Proxmox Server, apply this rule, and every validate_clusters call is checked against it from then on.
