WHAT IT DOES

What list_sdn_controllers does on Proxmox MCP Server

AI agents call list_sdn_controllers 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.

RISK

Why list_sdn_controllers is rated Low

This tool performs a simple enumeration of Software-Defined Networking controllers in the Proxmox infrastructure. It retrieves configuration data without creating, modifying, deleting, or executing any operations. Even in a security compromise scenario, an attacker could only gain visibility into network controller configuration, not manipulate infrastructure.

From the tool's definition Tool name 'list_sdn_controllers' and description 'List SDN controllers' indicate a retrieval operation with no modification of state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_sdn_controllers safely

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

list_sdn_controllers Allowed

list_sdn_controllers 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": {
    "list_sdn_controllers": {}
  }
}

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

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

FAQ

Questions about list_sdn_controllers

What does the list_sdn_controllers tool do? +

List SDN controllers (e.g. EVPN controller). It is categorised as a Read tool in the Proxmox MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_sdn_controllers? +

Register the Proxmox MCP Server MCP server in PolicyLayer and add a rule for list_sdn_controllers: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Proxmox MCP Server. Nothing to install.

What risk level is list_sdn_controllers? +

list_sdn_controllers is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_sdn_controllers? +

Yes. Add a rate_limit block to the list_sdn_controllers rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block list_sdn_controllers completely? +

Set action: deny in the PolicyLayer policy for list_sdn_controllers. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides list_sdn_controllers? +

list_sdn_controllers is provided by the Proxmox MCP Server MCP server (gethosthewalrus/proxmox-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
