## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__perfume-api__journal-search` `mcp__perfume-api__perfume-search` |
| 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

- **warn** Annotations that disagree with the tool in `occasion-edit` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "occasion-edit" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "occasion-edit" says "edit": a word for a change.
```


## Changes things (10)

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

### `family-map`

- 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 this when the user asks how fragrances are grouped or what a scent family is (for example woody, floral, amber, fresh, citrus), or wants the exemplar perfumes of one family (synonyms: scent families, fragrance categories, olfactive families). Returns Scento's own family system: the whole tree, or one family with its definition, subfamilies, exemplar perfumes and neighbouring families, with the scento.com guide. Don't use for one perfume's family (perfume-portrait), a perfumery term (perfumery-lexicon) or an occasion (occasion-edit).
```

### `house-portrait`

- 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 this when the user asks about a perfume house, brand or maison (for example Creed, Le Labo, Amouage): where it is from, when it was founded, its style and its signature perfumes. Returns country, founding year, style, signature perfumes with their families and the scento.com house page in the user's language. Don't use for one perfume (use perfume-portrait) or to list perfumes with a given note (material-match). If the house name is uncertain, call perfume-search with kind "house" first.
```

### `material-match`

- 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 this when the user wants perfumes, fragrances or colognes that contain specific notes or raw materials, optionally in the top, heart or base (synonyms: with notes of, built on, smells of, containing; for example vanilla and tobacco in the base). Returns the perfumes that have every material given, with house, where each sits in the pyramid and scento.com links in the user's language. Don't use to explain one material (note-portrait), to find perfumes like a named perfume (scent-neighbours) or for a mood or occasion (occasion-edit).
```

### `note-portrait`

- 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 this when the user asks what a note or raw material smells like or is (for example vetiver, oud, vanilla, iris, ambroxan, bergamot), whether it is natural or synthetic, or what it pairs with (synonyms: what does X smell like, ingredient, note). Returns how it smells, its family, natural or synthetic, pairings and perfumes that show it, with the scento.com page in the user's language. Don't use to find perfumes containing notes (use material-match) or to define a perfumery term such as sillage (perfumery-lexicon).
```

### `occasion-edit`

- The name "occasion-edit" says "edit": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks which perfume, fragrance or cologne to wear for one occasion, season or climate: wedding, office, date night, night out, weekend, everyday, gym or sport (workout), summer days, cold weather, first impressions, long-lasting or under-the-radar. Returns a short edit of perfumes with a line on why each fits and a scento.com link for each, in the user's language. The occasion is a fixed list, so pick the nearest value; omit gender_lean unless the user states one. For several occasions call it once per occasion. Don't use for a collection built around perfumes the user already loves (wardrobe-composer) or for similar scents (scent-neighbours).
```

### `perfume-contrast`

- 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:

Use this when the user asks to compare, contrast or choose between two to four named perfumes, fragrances or colognes (synonyms: versus, vs, difference between, which one). Returns the perfumes side by side on house, Scento family, top, heart and base notes, shared materials, character, seasons, hours, year and concentration, with scento.com links in the user's language. Don't use to find new perfumes (scent-neighbours or perfume-search) or to explain a single perfume (perfume-portrait).
```

### `perfume-portrait`

- 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.

Returns the verified note pyramid, Scento family and subfamily, character, seasons and hours, signature materials and the scento.com page in the user's language. Don't use to find similar perfumes (use scent-neighbours), compare perfumes (perfume-contrast) or search by mood (perfume-search).
```

### `perfumery-lexicon`

- Nothing in its name or description says what it does, so it is counted as a write.
