Get a list of all network interfaces on the device.
AI agents call get_interfaces to retrieve information from Nornir MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves interface information from network devices without modifying any state or executing commands that could alter device configuration or behavior. It is purely informational, consistent with other Read category tools like get_facts, get_config, and get_arp_table on the same server.
From the tool's definition Tool name 'get_interfaces' and description 'Get a list of all network interfaces on the device' indicate a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_interfaces gives an agent:
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:
{
"version": "1",
"default": "deny",
"tools": {
"get_interfaces": {}
}
}get_interfaces is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get a list of all network interfaces on the device. It is categorised as a Read tool in the Nornir MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Nornir MCP Server MCP server in PolicyLayer and add a rule for get_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 Nornir MCP Server. Nothing to install.
get_interfaces is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_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.
Set action: deny in the PolicyLayer policy for get_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.
get_interfaces 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.
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.
Free to start. No card required.
