DNS helpers for wide-area discovery (Tailscale + CoreDNS)

Agent View of the PolicyLayer registry record for `dns`. HTML page: https://policylayer.com/tools/openclaw/dns

## Facts

- Tool: `dns`
- Server: OpenClaw (`openclaw`) — https://policylayer.com/tools/openclaw.md
- Install: `npx -y openclaw`
- Homepage: https://www.npmjs.com/package/openclaw
- Risk category: Read (Low risk)
- Registry record: grade F, identity verified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "dns",
    "arguments": {}
  }
}
```

## Why dns is rated Low

DNS helpers typically perform lookups and queries to resolve hostnames or discover services. The description mentions 'discovery' which aligns with read/query operations. No write, execute, or destructive behavior is indicated.

From the tool's own definition: "'DNS helpers for wide-area discovery' implies querying/resolving DNS records, which is a read operation"

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "dns": {}
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
