## 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 (1)

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

### `calculate_due_date`

- 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
Use quando quiserem saber a data provável do parto (DPP) ou de quantas semanas estão. Informe a última menstruação (lmp), ou um ultrassom (data mais semanas e dias do laudo), ou a DPP que a médica passou. Retorna a DPP, as semanas e dias de hoje, o trimestre e o link da semana. Regra de Naegele (DUM + 280 dias).
```

## Only reads (4)

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

### `get_pregnancy_week`

- The name "get_pregnancy_week" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use quando perguntarem sobre uma semana específica da gravidez (4 a 40). Retorna o tamanho do bebê comparado a uma fruta (cm e g), o desenvolvimento do bebê, o que muda no corpo, dicas, perguntas para a consulta, os exames da fase e o link da página. Conteúdo geral em português, com base na Caderneta da Gestante 2026; não é diagnóstico.
```

### `get_pricing`

- The name "get_pricing" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use quando perguntarem quanto custa o app Nove ou o que é grátis. Retorna, em reais, o que o plano grátis inclui e seus limites, o Nove+ mensal (com dias grátis) e o Nove+ Gestação completa (pagamento único), e o que o Nove+ libera.
```

### `list_features`

- The name "list_features" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use quando perguntarem o que o app Nove faz ou se ele tem um recurso (lembrete de remédio, pré-natal, pressão e glicemia, cardápio da nutri, conversa com IA, álbum, nomes, parceiro, caderneta, plano de parto). Retorna cada recurso com nome, descrição e link da página.
```

### `search_nove`

- The name "search_nove" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use para achar no site da Nove o conteúdo sobre um assunto de gestação (enjoo, exames, plano de parto, pressão, remédios na gravidez) ou sobre o app. Retorna até 5 páginas com título, resumo, trecho e link, da mais relevante para a menos.
```

| Fact | Observed |

| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `1` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

- **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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://nove.care/mcp: tools/list returned 5 tools to an anonymous client, including calculate_due_date (write)
