What mdk4 does on Nyxstrike
AI agents invoke mdk4 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 mdk4 is rated High
MDK4 is a wireless attack tool capable of executing denial-of-service, deauthentication floods, and other disruptive operations against wireless networks. Even though the description is empty, the tool name and context (offensive security platform, sibling wireless attack tools) strongly imply execution of potentially destructive network attacks.
From the tool's definition Tool name 'mdk4' refers to the well-known wireless network stress-testing and attack tool (MDK4), used for beacon flooding, deauthentication attacks, and other disruptive wireless operations.

The rule that runs mdk4 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 mdk4, this is the rule to start with:
mdk4 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 mdk4 call is checked against it from then on.
Questions about mdk4
mdk4 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 mdk4: 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.
mdk4 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 mdk4 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 mdk4. 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.
mdk4 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.
