Why reorder_config_interfaces needs a policy

Reordering interfaces modifies the configuration profile by changing the order/priority of network interfaces. This is a reversible write operation (the order can be changed back), but misuse could disrupt network connectivity for running instances.

POLICY

How to control reorder_config_interfaces

PolicyLayer is an MCP gateway — it sits between your AI agents and Linode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for reorder_config_interfaces:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "reorder_config_interfaces": {
      "limits": [
        {
          "counter": "reorder_config_interfaces_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

reorder_config_interfaces stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Linode MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about reorder_config_interfaces

What does the reorder_config_interfaces tool do? +

Reorder interfaces for a configuration profile. It is categorised as a Write tool in the Linode MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on reorder_config_interfaces? +

Register the Linode MCP Server MCP server in PolicyLayer and add a rule for reorder_config_interfaces: 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 Linode MCP Server. Nothing to install.

What risk level is reorder_config_interfaces? +

reorder_config_interfaces is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit reorder_config_interfaces? +

Yes. Add a rate_limit block to the reorder_config_interfaces 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 reorder_config_interfaces completely? +

Set action: deny in the PolicyLayer policy for reorder_config_interfaces. 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 reorder_config_interfaces? +

reorder_config_interfaces is provided by the Linode MCP Server MCP server (takashito/linode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Linode MCP Server tool call.

Start from Linode MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
