AI agents call resolveName to retrieve information from MCP Ethers Wallet without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
In the Ethereum ecosystem, 'resolveName' almost certainly refers to resolving an ENS (Ethereum Name Service) name to an address — a pure read/query operation with no side effects. No funds are moved, no data is written, and nothing is executed. The empty description reduces confidence, but the name and context strongly suggest a read operation.
From the tool's definition Tool name 'resolveName' suggests ENS (Ethereum Name Service) resolution, which is a read-only lookup operation. Description is empty, lowering confidence.
Documented attack patterns abuse exactly the kind of access resolveName gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Ethers Wallet, and nothing reaches the server without passing your rules. This is the rule we recommend for resolveName:
{
"version": "1",
"default": "deny",
"tools": {
"resolveName": {}
}
}resolveName is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

resolveName. It is categorised as a Read tool in the MCP Ethers Wallet MCP Server, which means it retrieves data without modifying state.
Register the MCP Ethers Wallet MCP server in PolicyLayer and add a rule for resolveName: 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 MCP Ethers Wallet. Nothing to install.
resolveName 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 resolveName 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 resolveName. 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.
resolveName is provided by the MCP Ethers Wallet MCP server (crazyrabbitltc/mcp-ethers-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Ethers Wallet, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
