Reverse resolves an Ethereum address to its primary .wei name.
AI agents call reverseResolveWNS 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/query operation, resolving an Ethereum address to a human-readable name. It retrieves data with no side effects, no state changes, and no financial implications.

Documented attack patterns abuse exactly the kind of access reverseResolveWNS 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 reverseResolveWNS:
{
"version": "1",
"default": "deny",
"tools": {
"reverseResolveWNS": {}
}
}reverseResolveWNS is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Reverse resolves an Ethereum address to its primary .wei name. It is categorised as a Read tool in the Agentek Eth MCP Server, which means it retrieves data without modifying state.
Register the Agentek Eth MCP server in PolicyLayer and add a rule for reverseResolveWNS: 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 Agentek Eth. Nothing to install.
reverseResolveWNS is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the reverseResolveWNS 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 reverseResolveWNS. 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.
reverseResolveWNS is provided by the Agentek Eth MCP server (nanidao/agentek). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Agentek Eth, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
