**7 tools: 1 do something that can't be undone and 6 change things.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 1 | ask |
| Changes things | write | 6 | ask |
| Only reads | read | 0 | allow |

## Exfil surface

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

| 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. | `mcp__soma-protocol__soma_send` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `soma_send`

- The name "soma_send" says "send": a word for sending, and what is sent cannot be taken back.
- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The name "soma_send" says "send": it sends or publishes something to other people. The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Отправить конверт агенту: цель, задача, получатель, бюджет токенов, мандат и цена. Конверт подписывается и попадает в очередь.
```

## Changes things (6)

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

### `soma_claim`

- 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
Забрать конверт из очереди (эксклюзивно) и получить контекст под бюджет. Если у работы назначена цена — нужна квитанция.
```

### `soma_complete`

- 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
Закрыть конверт результатом работы.
```

### `soma_inbox`

- 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
Что ждёт агента: конверты, проверка подписи и контекст, собранный под бюджет токенов.
```

### `soma_route`

- 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
Подобрать исполнителя по capability, мандату и цене. Если кандидата нет — вернётся честная причина отказа.
```

### `soma_stats`

- 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
Состояние хаба: конверты по статусам, факты, связи, холодные артефакты.
```

### `soma_verify`

- 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
Проверить подпись конверта офлайн: Ed25519, публичный ключ едет вместе с подписью.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__soma-protocol__soma_send",
      "mcp__soma-protocol__soma_inbox",
      "mcp__soma-protocol__soma_claim",
      "mcp__soma-protocol__soma_complete",
      "mcp__soma-protocol__soma_route",
      "mcp__soma-protocol__soma_verify",
      "mcp__soma-protocol__soma_stats"
    ],
    "deny": []
  }
}
```

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

- `mcp__soma-protocol__soma_send`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:17:52.786Z, unchanged since 2026-10-22T15:17:52.786Z. 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 | `7` |
| 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` |

- **high** 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 7 tools that change things (1 irreversible, 6 write). Whether a call also works without credentials was not tested: tools are never called.

https://rta.lat/soma-protocol/mcp: tools/list returned 7 tools to an anonymous client, including soma_send (irreversible), soma_inbox (write), soma_claim (write), soma_complete (write), soma_route (write) and 2 more
