AI agents use create_lab_network to create or update resources in EVE-NG MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your EVE-NG MCP Server environment.
The tool creates a new network resource within an EVE-NG lab environment. This is a Write operation because it modifies state by adding a new network object. Severity is medium because creating unwanted networks could disrupt a lab topology or consume resources, but the operation is reversible and does not directly execute arbitrary code or permanently destroy data.
From the tool's definition Tool name and description indicate creation of a network resource: 'Create a network in a lab.' This is a reversible modification operation (networks can be deleted via delete_lab_network), not a read-only query or destructive operation.
Documented attack patterns abuse exactly the kind of access create_lab_network 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 create_lab_network:
{
"version": "1",
"default": "deny",
"tools": {
"create_lab_network": {
"limits": [
{
"counter": "create_lab_network_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_lab_network stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Create a network in a lab. It is categorised as a Write tool in the EVE-NG MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the EVE-NG MCP Server MCP server in PolicyLayer and add a rule for create_lab_network: 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.
create_lab_network is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_lab_network 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 create_lab_network. 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.
create_lab_network 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.
