Implementation Reference
- The main handler function for the 'create_lab_network' tool. It handles input validation, EVE-NG connection check, creates the network using eveng_client.add_lab_network, and returns formatted TextContent responses.@mcp.tool() async def create_lab_network(arguments: CreateNetworkArgs) -> list[TextContent]: """ Create a network in a lab. This tool creates a new network (cloud, bridge, NAT, etc.) in the lab with the specified type and positioning.
