List all vNICs (Ethernet interfaces) or filter by LAN connectivity policy
AI agents call list_vnics to retrieve information from Intersight MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that retrieves information about virtual network interfaces. The use of 'list' and the passive description of filtering existing data confirms it performs only queries without creating, modifying, executing, or deleting resources. The blast radius is minimal—an AI agent calling this tool can only view network configuration data, not alter infrastructure.
From the tool's definition Tool name 'list_vnics' and description 'List all vNICs (Ethernet interfaces) or filter by LAN connectivity policy' indicate retrieval/querying of existing network interface data with no modification or side effects.
Documented attack patterns abuse exactly the kind of access list_vnics gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Intersight MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_vnics:
{
"version": "1",
"default": "deny",
"tools": {
"list_vnics": {}
}
}list_vnics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all vNICs (Ethernet interfaces) or filter by LAN connectivity policy. It is categorised as a Read tool in the Intersight MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Intersight MCP Server MCP server in PolicyLayer and add a rule for list_vnics: 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 Intersight MCP Server. Nothing to install.
list_vnics 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 list_vnics 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 list_vnics. 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.
list_vnics is provided by the Intersight MCP Server MCP server (jim-coyne/intersight_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Intersight MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
