WHAT IT DOES

What x402PlanPayment does on Agentek Eth

AI agents invoke x402PlanPayment to trigger actions in Agentek Eth. 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.

RISK

Why x402PlanPayment is rated High

x402PlanPayment 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.

RECOMMENDED RULE

The rule that runs x402PlanPayment safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Agentek Eth, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For x402PlanPayment, this is the rule to start with:

x402PlanPayment Rate-limited

x402PlanPayment 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.
