Why get_interfaces_ip needs a policy

This tool retrieves IP address information from network devices without modifying, executing operations on, or deleting any data. It is a passive query operation similar to other informational tools on the server. The blast radius of misuse is limited to information disclosure about network infrastructure.

From the tool's definition Tool name 'get_interfaces_ip' and description 'Get IP address information for all interfaces' indicate a data retrieval operation with the verb 'Get'.

POLICY

How to control get_interfaces_ip

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

policy.json

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

get_interfaces_ip is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Nornir 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 get_interfaces_ip

What does the get_interfaces_ip tool do? +

Get IP address information for all interfaces. It is categorised as a Read tool in the Nornir MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_interfaces_ip? +

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

What risk level is get_interfaces_ip? +

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

Can I rate-limit get_interfaces_ip? +

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

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

get_interfaces_ip is provided by the Nornir MCP Server MCP server (yhvh-chen/nornir_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Nornir MCP Server tool call.

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