## 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 (6)

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

### `armar_carrito_por_texto`

- 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
EN UN SOLO PASO: recibe lo que pidió la persona en texto libre (ej. "2 chombas talle 10 y un buzo talle 10") y devuelve el link al carrito con precio publicado de cada renglón, y lo que no se pudo resolver con el motivo ("no encontré X", "sin stock", "¿qué color?"). NO compra ni cobra. Preferila antes que buscar_productos + armar_pedido.
```

### `armar_kit`

- 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
EN UN SOLO PASO: el kit armado por la tienda (ej. "1er grado", "invierno") con un talle o la edad → link al carrito. Lo que no tiene stock o talle queda afuera con aviso. Si no se indica kit y hay varios, devuelve la lista. NO compra ni cobra.
```

### `armar_pedido`

- 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
NO compra ni cobra. Arma un link al carrito de la tienda con las prendas precargadas; la persona lo abre, completa sus datos y paga en la tienda. Los precios los calcula la tienda.
```

### `buscar_productos`

- 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 uniformes publicados en la tienda por texto (prenda, colegio, color) y opcionalmente por talle con stock. Devuelve hasta 20 productos con precio "desde" en ARS.
```

### `talle_sugerido`

- 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
Sugiere un talle por edad (y opcionalmente para una prenda). Es una sugerencia, nunca una certeza: que lo confirme con la tabla de medidas. Si la tienda tiene el ayudante apagado, lo dice.
```

### `ver_producto`

- 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
Un producto (id = "modelo" de buscar_productos) con el precio publicado de cada talle/color y si hay stock (sí/no o preventa). No informa cantidades exactas.
```

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

https://colegios.shop/mcp: tools/list returned 6 tools to an anonymous client, including buscar_productos (write), ver_producto (write), armar_pedido (write), armar_carrito_por_texto (write), armar_kit (write) and 1 more
