No check matched anything in these tool definitions.


## Changes things (4)

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

### `chercher_empreinte`

- 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
Rend chaque dépôt de cette empreinte SHA-256 : jour, ligne du registre, adresse du reçu. Aucun dépôt : le document n’a pas été daté par ce service.
```

### `dater_empreinte`

- 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
Inscrit dans le registre public l’empreinte SHA-256 d’un document que l’utilisateur garde ; le document n’est jamais envoyé. Rend le reçu, qui prouve que ce document existait à cette date, sans modification.
```

### `dater_url`

- 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
Le service lit lui-même l’adresse publique (http ou https, 20 Mo et 30 s au plus) et inscrit l’empreinte SHA-256 des octets lus dans le registre public, ancré dans Bitcoin. Rend le reçu : à remettre à l’utilisateur, il prouve que ce contenu était servi à cette adresse à cet instant. Une même adresse se lit une fois par jour.
```

### `lire_recu`

- 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
Rend la ligne publique d’un reçu par son identifiant (64 caractères hexadécimaux) : empreinte, jour, ligne du registre, et pour un acte de collectivité son adresse pérenne, à citer.
```
