## 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__domhaul__check_domains` `mcp__domhaul__get_tld_prices` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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
Check whether domain names are actually available to register, using live registry (RDAP) data. Use this when suggesting domain names (verify availability before presenting them, never assume a name is unregistered) or when the user asks whether specific domains are available. Accepts up to 50 fully-qualified domains (e.g. 'brewlog.app'). Returns availability, the registrar for taken domains, a 0-100 brandability score, an estimated resale value, the price in USD (price_usd for term_years, quote it rather than estimating; price_source 'checkout' is the expected charge at buy_url, confirmed before payment), and buy_url, the domhaul checkout page where the user can purchase the domain. If too few names are available, generate more candidates and call again.
```

## Only reads (1)

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

### `get_tld_prices`

- The name "get_tld_prices" says "get": a word for reading.
- 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
Get registrar retail first-year price estimates in USD for top-level domains (.com, .io, .app, .dev, .ai, …). Use this when the user is comparing TLD options, e.g. 'should I get the .com or the .io?'. For the exact purchase price of a specific domain, use check_domains instead.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__domhaul__get_tld_prices"
    ],
    "ask": [
      "mcp__domhaul__check_domains"
    ],
    "deny": []
  }
}
```

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

- `mcp__domhaul__check_domains`: untrusted-input
- `mcp__domhaul__get_tld_prices`: untrusted-input
