## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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 (4)

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

### `prism_answer`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Единый порядок слоёв: реестр, вывеска, учреждение, карточки людей, списки города, карта, справочник контактов. Один вопрос — один ответ, тот же самый, что получает человек в боте и на сайте. Списком не отдаётся: карточки людей (что предлагают, что ищут) отвечают только на прямой вопрос, обход закрыт даже здесь — это единственный наш актив, ценность которого мы сами ещё не измерили. Объявления досок в этот инструмент не входят — право на переотдачу не оформлено.
```

### `prism_ask`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Всё, что известно про ИНН, с источником и датой у каждого значения. Отсутствие размечено пятью способами: found, none, unknown, not_provided, withheld — так видно, повторять ли вопрос и куда идти дальше. Принимает до ста ИНН через запятую.
```

### `prism_nearby`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Слой карты, а не реестр: заведения с вывесками и координатами. Связь вывески с ИНН нигде не установлена и отдаётся как гипотеза с указанием, чем её подтвердить. Реестр на этот вопрос ответить не может — координат в нём нет.
```

### `prism_needs`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Список дыр, нарисованный чужими вопросами: что спрашивали и на что мы не ответили. Показывается то, о чём спросили не меньше трёх разных сторон. Дыру можно закрыть, принеся факт — он проходит те же ворота записи, что и наши собственные данные.
```

## Only reads (1)

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

### `prism_find`

- The name "prism_find" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Кто есть на территории по виду деятельности, размеру, налоговому режиму, выручке, задолженности. В каждом ответе знаменатель — сколько всего субъектов на этой территории, без него доля бессмысленна. Проверку продают все, обнаружение не продаёт никто.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__hub__prism_find"
    ],
    "ask": [
      "mcp__hub__prism_ask",
      "mcp__hub__prism_nearby",
      "mcp__hub__prism_needs",
      "mcp__hub__prism_answer"
    ],
    "deny": []
  }
}
```

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `4` |

- **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 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://prismfact.com/mcp: tools/list returned 5 tools to an anonymous client, including prism_ask (write), prism_nearby (write), prism_needs (write), prism_answer (write)
