## Findings

- **warn** Annotations that disagree with the tool in `punycode_convert` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "punycode_convert" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "punycode_convert" says "convert": a word for a change.
```


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `ip_geolocation`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Geolocate an IPv4/IPv6 address: country, region, city, ISP and organisation.
```

### `punycode_convert`

- The name "punycode_convert" says "convert": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Convert a domain between Unicode (IDN) and Punycode/ACE (xn--) form, both directions, auto-detected.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `whois_lookup`

- The name "whois_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up WHOIS/RDAP data for a domain: registration state (registered / available / reserved / unsupported / unknown) and the full raw registry record (registrar, dates, name servers, status). Supports 1400+ zones including IDN / Cyrillic domains.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `whois`:

```json
{
  "permissions": {
    "allow": [
      "mcp__whois__whois_lookup"
    ],
    "ask": [
      "mcp__whois__ip_geolocation",
      "mcp__whois__punycode_convert"
    ],
    "deny": []
  }
}
```
