**3 tools: 3 change things.**

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__nomok__check_domains` `mcp__nomok__check_name` `mcp__nomok__suggest_names` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "generate": a word for a change.
```


## Changes things (3)

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

### `check_domains`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Checks domain name availability for up to 10 names on chosen extensions (DNS + RDAP registry lookup). Default extensions: .com, .net, .org, .io, .app, .dev, .co, .fr. Supported: .com, .fr, .net, .org, .info, .biz, .co, .de, .uk, .it, .es, .be, .ch, .nl, .eu, .ca, .us, .io, .ai, .me, .gg, .tv, .app, .dev, .tech, .studio, .design, .art, .shop, .store, .online, .xyz. Ideal to compare several name ideas quickly. Available domains come with a registration link and indicative price.
```

### `check_name`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Checks whether a name/handle is available on 70+ platforms at once: domain names (.com, .fr, .io, .app…), social networks (Instagram, TikTok, X, YouTube…), creative and dev platforms (GitHub, Behance…), e-commerce, freelance, gaming and company registries. Takes 5-15 s on first call (results cached 10 min). Statuses: available, likely_available, taken, manual (cannot be checked automatically), unknown (check failed). Never present manual/unknown results as available. Available domains come with a registration link. Each call is a full live search: to compare many name ideas, first use check_domains (up to 10 names per call), then check_name only on the shortlist.
```

### `suggest_names`

- The description's first verb is "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Generates common variants of a name (get-, try-, -hq, -app, -studio…) and checks which ones are available as a domain (.com by default). Use when the exact name is taken.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__nomok__check_name",
      "mcp__nomok__check_domains",
      "mcp__nomok__suggest_names"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__nomok__check_name`: untrusted-input
- `mcp__nomok__check_domains`: untrusted-input
- `mcp__nomok__suggest_names`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:23:13.309Z, unchanged since 2026-10-22T14:23:13.309Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `3` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://nomok.app/mcp: tools/list returned 3 tools to an anonymous client, including check_name (write), check_domains (write), suggest_names (write)
