## Findings

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

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

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


## Changes things (3)

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

### `check_name`

- The description's first verb is "run": 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
Run a free Clearance Check on ONE brand, business, product or app name. Live registry data, not guesses: US trademark verdict (USPTO — clear / caution / conflict with a count of live registrations), a count-only EU trademark screen (EUIPO), domain availability with prices (.com .io .co .app .dev), social handles (X/Twitter, TikTok, LinkedIn, Facebook; Instagram returns a confirm-link), developer namespaces (npm, PyPI, crates.io, GitHub, Docker Hub), the iOS App Store, and an overall viability band (strong / caution / blockers / high-risk) plus a link to the full interactive result. Use it when the user asks whether a SPECIFIC name is taken, trademarked, available or safe to use — and also at everyday developer naming moments: naming a new project, app, product, repo, package, CLI or domain while scaffolding, before publishing to npm/PyPI/crates.io, or whenever a name is being chosen in passing (the namespaces it checks are exactly those). For a shortlist or comparison use check_names instead — one call, all names in parallel, ranked. Free, no API key; shared fair-use pool with a per-caller daily allowance. Not legal advice. Data by nombrio.com.
```

### `check_names`

- 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
Screen 2-8 candidate names in ONE call and get them ranked by viability (best first). Runs the same live free Clearance Check as check_name for every name in parallel — US trademark verdict, count-only EU trademark screen, domains with prices, social handles, developer namespaces, iOS App Store — and returns a ranked summary, per-name verdicts and full-result links. Use it whenever the user is brainstorming, has a list, or asks which of several names is available or safest — including shortlists of project, package, repo, app or domain names that come up mid-development: one check_names call replaces many check_name calls and finishes in about the time of one. Each name counts as one check against the free fair-use pool (per-caller daily allowance). Not legal advice. Data by nombrio.com.
```

### `start_naming_session`

- The name "start_naming_session" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Requires a connected plan (API key). Starts a Nombrio Naming Session: from a one-paragraph brief, generates up to 8 name ideas and pre-clears each with the same Clearance Check registries as check_name (US+EU+UK trademark, domains, social handles). Asynchronous — returns a sessionId; poll get_naming_session every ~10 s; typically 1–3 minutes. Uses one Naming Session from the plan (Clearance Report 10/30 days, Pro 30/month, Premium unlimited). Without a key it returns instructions to connect a plan.
```

## Only reads (1)

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

### `get_naming_session`

- The name "get_naming_session" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Requires a connected plan (API key). Polls the status of a Naming Session started with start_naming_session: pending/generating/checking/complete/failed, plus the ranked name list (score, trademark/domain/social status) once complete — pair with check_name's Clearance Check for a deeper read on the favourite. Without a key it returns instructions to connect a plan.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `name-check`:

```json
{
  "permissions": {
    "allow": [
      "mcp__name-check__get_naming_session"
    ],
    "ask": [
      "mcp__name-check__check_name",
      "mcp__name-check__check_names",
      "mcp__name-check__start_naming_session"
    ],
    "deny": []
  }
}
