What massdns_scan does on Nyxstrike
AI agents invoke massdns_scan 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 massdns_scan is rated High
MassDNS is a well-known high-performance DNS stub resolver used for bulk DNS resolution and subdomain enumeration — a network-facing reconnaissance/execution tool. On an offensive security platform alongside attack suites and payload generators, it is used to actively probe external DNS infrastructure. The description is empty, so category is inferred from the tool name and server context.

The rule that runs massdns_scan 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 massdns_scan, this is the rule to start with:
massdns_scan 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 massdns_scan call is checked against it from then on.

massdns_scan 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 massdns_scan 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 massdns_scan. 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.
massdns_scan 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.
