What josephus does on ScorpTech x402 API
AI agents invoke josephus to trigger actions in ScorpTech x402 API. 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
k | integer | Yes | |
n | integer | Yes |
Parameters from the server's own tool schema.
Why josephus is rated High
josephus triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

The rule that runs josephus safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For josephus, this is the rule to start with:
josephus 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 ScorpTech x402 API, apply this rule, and every josephus call is checked against it from then on.
