AI agents call resolve_name to retrieve information from Gulltoppr without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
name | string | Yes | An ENS name (vitalik.eth) or a 0x address. |
chain | string | — | Chain alias ("ethereum", "base", "optimism", "arbitrum", "polygon", "local") or numeric chain id. |
Parameters from the server's own tool schema.
This tool performs a lookup/query operation converting ENS names to addresses or vice versa. It is purely a read operation with no side effects, no data modification, and no financial implications.
From the tool's definition Resolve an ENS name to an address, or an address to its primary ENS name
Attacks that exploit this kind of access
Resolve an ENS name to an address, or an address to its primary ENS name. It is categorised as a Read tool in the Gulltoppr MCP Server, which means it retrieves data without modifying state.
resolve_name accepts 2 parameters: name, chain. Required: name. The full parameter table on this page comes from the server's own tool schema.
Register the Gulltoppr MCP server in PolicyLayer and add a rule for resolve_name: 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 Gulltoppr. Nothing to install.
resolve_name 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 resolve_name 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 resolve_name. 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.
resolve_name is provided by the Gulltoppr MCP server (https://mcp.gulltoppr.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
