AI agents call list_network_types to retrieve information from EVE-NG MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of available network types in the EVE-NG system. It has no side effects, does not modify state, and does not trigger execution or deletion of resources. The blast radius of misuse is minimal—an agent could only enumerate what network types exist, which is informational and reversible.
From the tool's definition Tool name is 'list_network_types' and description states it 'List available network types in EVE-NG' — a query operation that retrieves and enumerates configuration data without modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access list_network_types gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and EVE-NG MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_network_types:
{
"version": "1",
"default": "deny",
"tools": {
"list_network_types": {}
}
}list_network_types is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List available network types in EVE-NG. It is categorised as a Read tool in the EVE-NG MCP Server MCP Server, which means it retrieves data without modifying state.
Register the EVE-NG MCP Server MCP server in PolicyLayer and add a rule for list_network_types: 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 EVE-NG MCP Server. Nothing to install.
list_network_types 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_network_types 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_network_types. 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_network_types is provided by the EVE-NG MCP Server MCP server (moimran/eveng-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from EVE-NG 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.
