WHAT IT DOES

What resolve_ens does on EVM MCP Server

AI agents call resolve_ens to retrieve information from EVM MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why resolve_ens is rated Low

This tool performs a read-only lookup, converting an ENS name to an Ethereum address. It has no side effects, does not modify any state, and cannot cause harm through misuse beyond revealing address mappings which are already public on-chain.

RECOMMENDED RULE

The rule that runs resolve_ens safely

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

resolve_ens Allowed

resolve_ens is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "resolve_ens": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect EVM MCP Server, apply this rule, and every resolve_ens call is checked against it from then on.
