# resolve_address

Reverse resolution: given an XRPL address, return its primary XRPName (if set) and the full list of names owned by the wallet. Use when the user says "who owns [address]?", "look up this wallet", or "what names does [address] have?", or when chained with get_domain_profile to explore a wallet. Returns found:false if the address owns no XRPName.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why resolve_address is rated Medium

An AI agent can call resolve_address faster than any human can review: one bad instruction and it creates or modifies resources in XRPName by the hundred, each call as confident as the last.

## Use case

AI agents use resolve_address to create or update resources in XRPName, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your XRPName environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches XRPName:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "resolve_address": {
      "limits": [
        {
          "counter": "resolve_address_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
