AI agents call get_network_interfaces to retrieve information from Wireshark 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 or enumerates network interfaces available on the system—a read-only operation with no side effects, data modification, or execution capabilities. Misuse could enable network reconnaissance but poses minimal direct risk compared to capture or analysis functions on the same server. Classified as Read with low severity.
From the tool's definition Tool name 'get_network_interfaces' indicates retrieval of network interface information with no modification capability. The server context (Wireshark network analysis) confirms this is a passive reconnaissance function.
Documented attack patterns abuse exactly the kind of access get_network_interfaces gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Wireshark MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_network_interfaces:
{
"version": "1",
"default": "deny",
"tools": {
"get_network_interfaces": {}
}
}get_network_interfaces is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_network_interfaces. It is categorised as a Read tool in the Wireshark MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Wireshark MCP Server MCP server in PolicyLayer and add a rule for get_network_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 Wireshark MCP Server. Nothing to install.
get_network_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_network_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_network_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_network_interfaces is provided by the Wireshark MCP Server MCP server (mixelpixx/wireshark-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Wireshark 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.
