Get the registration fee for a .wei name based on label length.
AI agents call getWNSFee to retrieve information from Agentek Eth without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a lookup to retrieve fee information based on input parameters (label length). It has no side effects, does not execute code or transactions, and does not modify or delete data.
From the tool's definition The tool description states it 'Get[s] the registration fee' — a query operation that retrieves pricing information without modifying state or executing external operations.
Documented attack patterns abuse exactly the kind of access getWNSFee gives an agent:
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 getWNSFee:
{
"version": "1",
"default": "deny",
"tools": {
"getWNSFee": {}
}
}getWNSFee is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
