Why intentRegisterSubdomainWNS needs a policy

Registering a subdomain on a blockchain naming system (WNS) involves submitting an on-chain transaction that typically requires paying registration fees in cryptocurrency. This commits financial obligations (gas fees and potentially registration costs) on the Ethereum network, placing it in the Financial category.

How to control intentRegisterSubdomainWNS

PolicyLayer is an MCP gateway — it sits between your AI agents and Agentek Eth, and nothing reaches the server without passing your rules. This is the rule we recommend for intentRegisterSubdomainWNS:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "intentRegisterSubdomainWNS": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to intentRegisterSubdomainWNS is blocked until a human approves it. The rest of the server keeps working.
