What httpx_probe does on Nyxstrike
AI agents invoke httpx_probe 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 httpx_probe is rated High
httpx is a fast HTTP probing tool commonly used in offensive security to discover live hosts, open ports, and web services. On a penetration testing platform alongside attack suite generators and payload tools, this likely executes active network probing against targets.

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