## 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__devis__get_legal_mentions` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__devis__create_quote` `mcp__devis__render_quote_html` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `create_quote`

- The name "create_quote" says "create": a word for a change.
- Tag outbound: The input takes a destination (input.company.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Calcule les totaux (HT, TVA par taux, TTC) d'un devis français, applique la franchise en base de TVA (art. 293 B du CGI) si demandée, et signale par des avertissements les mentions obligatoires manquantes (jamais d'invention de valeur).
```

### `render_quote_html`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a destination (input.company.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Génère un devis HTML A4 autonome et imprimable, dans l'un des 4 modèles (classique, moderne, bandeau, minimal), avec les mêmes calculs et mentions légales que create_quote.
```

## Only reads (1)

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

### `get_legal_mentions`

- The name "get_legal_mentions" says "get": a word for reading.
- Tag untrusted-input: The name "get_legal_mentions" says "get" and "mention": it reads comments, which other people can write. The description's first sentence says "mention": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Retourne la liste des mentions obligatoires d'un devis professionnel français, avec leurs sources officielles (service-public.gouv.fr, economie.gouv.fr, autoentrepreneurs.org pour la franchise en base de TVA).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__devis__get_legal_mentions"
    ],
    "ask": [
      "mcp__devis__create_quote",
      "mcp__devis__render_quote_html"
    ],
    "deny": []
  }
}
```

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

- `mcp__devis__create_quote`: outbound
- `mcp__devis__get_legal_mentions`: untrusted-input
- `mcp__devis__render_quote_html`: outbound
