What nbtscan_netbios does on Nyxstrike
AI agents invoke nbtscan_netbios to trigger actions in Nyxstrike. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why nbtscan_netbios is rated High
NBTScan is a tool that scans IP networks for NetBIOS name information, actively probing network hosts. On an offensive security/penetration testing platform, this constitutes active network reconnaissance/execution. Empty description lowers confidence slightly, but the tool name and server context make active scanning highly likely.
From the tool's definition Tool name 'nbtscan_netbios' on a penetration testing platform; description is empty but name strongly implies NetBIOS network scanning

The rule that runs nbtscan_netbios safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nyxstrike, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For nbtscan_netbios, this is the rule to start with:
nbtscan_netbios stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nyxstrike, apply this rule, and every nbtscan_netbios call is checked against it from then on.
Questions about nbtscan_netbios
nbtscan_netbios is a execute tool on the Nyxstrike MCP server. It is categorised as a Execute tool in the Nyxstrike MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Nyxstrike MCP server in PolicyLayer and add a rule for nbtscan_netbios: 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 Nyxstrike. Nothing to install.
nbtscan_netbios is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the nbtscan_netbios 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 nbtscan_netbios. 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.
nbtscan_netbios is provided by the Nyxstrike MCP server (CommonHuman-Lab/nyxstrike). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
