What capture_network_traffic does on Ludus FastMCP
AI agents call capture_network_traffic to retrieve information from Ludus FastMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why capture_network_traffic is rated Low
Network traffic capture is fundamentally a read operation—it observes and retrieves network data without altering, creating, deleting, or executing anything. The empty description lowers confidence slightly, but the name clearly indicates a passive monitoring function typical in cyber range and security testing environments.

The rule that runs capture_network_traffic safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ludus FastMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For capture_network_traffic, this is the rule to start with:
capture_network_traffic is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ludus FastMCP, apply this rule, and every capture_network_traffic call is checked against it from then on.
