## 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__guia__ficha_camping` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `buscar_campings`

- 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
Busca campings de la guía BuscaTuCamping en una zona (población, provincia, comunidad o nombre del camping), con filtros opcionales de país, perros, piscina, bungalows, playa y fechas de apertura (un día con abierto_en o un rango con abierto_desde y abierto_hasta). Devuelve hasta 30 campings con su población, estado de temporada, precio orientativo si lo hay y la URL de su ficha.
```

### `ficha_camping`

- 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 outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Datos de un camping de la guía BuscaTuCamping: población, provincia, país, coordenadas, dirección, teléfono, web, temporada (estado en la fecha, detalle y cuándo y dónde se verificó), precio orientativo por noche de una parcela, servicios, si admite perros, ofertas vigentes y la URL de su ficha. Identifíquelo por id (el que devuelve buscar_campings) o por la URL de su ficha.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__guia__buscar_campings",
      "mcp__guia__ficha_camping"
    ],
    "deny": []
  }
}
```

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

- `mcp__guia__ficha_camping`: outbound

- **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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://www.buscatucamping.com/mcp-guia: tools/list returned 3 tools to an anonymous client, including buscar_campings (write), ficha_camping (write), campings_cerca (write)
