## Exfil surface

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

| 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__duos__duos_crear_consulta` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__duos__duos_crear_consulta` |

## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `duos_consultar_cuota`

- 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
Devuelve el plan, las consultas disponibles y el presupuesto propio de IA. No genera respuestas ni consume consultas. No muestra otros clientes ni el gasto global.
```

### `duos_crear_consulta`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.chat_id): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Crea una consulta autenticada: dos análisis iniciales separados y una revisión cruzada de cada modelo. Envía el texto a proveedores de IA y puede consumir UNA consulta del plan y gasto de IA. Requiere intención del cliente; no usar como comprobación gratuita de conexión. Devuelve jobId/status para consultar el resultado con duos_obtener_resultado. Reutiliza el MISMO idempotency_key UUID si reintentas la MISMA pregunta; nunca cambies el mensaje con esa clave.
```

### `duos_listar_consultas`

- 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
Lista una página del historial propio de consultas. Requiere el permiso separado duos:history. No genera respuestas. Continúa con nextOffset cuando no sea null.
```

### `duos_obtener_resultado`

- 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
Recupera únicamente un trabajo propio creado antes. No vuelve a llamar a modelos ni descuenta consultas. Si sigue pendiente, respeta pollAfterMs antes de volver a leer. Un error no es un resultado completo.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__duos__duos_consultar_cuota",
      "mcp__duos__duos_crear_consulta",
      "mcp__duos__duos_obtener_resultado",
      "mcp__duos__duos_listar_consultas"
    ],
    "deny": []
  }
}
```

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

- `mcp__duos__duos_crear_consulta`: untrusted-input, outbound
