## 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__yacht-charter__request_quote` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__yacht-charter__best_deals` `mcp__yacht-charter__price_range` `mcp__yacht-charter__request_quote` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `best_deals`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Discounted departures of this site's yachts, read from the live inventory: only a discount the source itself states (a special, or a price under its list price), never a computed gap. By default from tomorrow to 30 days ahead; a departure the yacht's calendar shows taken is left out. One row per yacht: its page link (the id get and request_quote take) and photo (absolute URLs) and its departures, each with its dates, every route it leaves on, nights, price, list price, mandatory extras and saving, in the order asked. Narrow with the same typed filters as search. When none match, the answer is the nearest deals (the window after, the place around, a bound let go) and nearest says what was widened. Paged: total and cursor. Works without a contact (browsing: fewer rows).
```

### `request_quote`

- The name "request_quote" says "request": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Ask this site's desk for a formal quote on one or more yachts, for the person. Pass the page links a search, best_deals or get returned, the days and the party, and anything the person wants the desk to know. The desk answers with a written quote to the person's own email or phone, with every cost on it; this answer only says it was received and where the quote goes. Nothing is booked or paid: the person confirms the booking with the desk. Ask the person before calling it.
```

## Changes things (1)

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

### `price_range`

- 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.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
What a stay typically costs: the range (p25, median, p75 in minor units of the currency) of open departures for a place, month and party, optionally one type, with how many items it is from, the cheapest published one that fits and when the figures were built; seasonNote says in words how another month compares. An unknown place answers with the places that have figures. Works without a contact.
```

## Only reads (2)

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

### `get_yacht`

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

Description, as the server wrote it:

```untrusted-server-text
One yacht: its facts and terms as the source states them (packages, included, required and optional extras, deposit, check-in days and times, stay limits, equipment, the operator's descriptions), and its availability: with from / to, that stay's status and price and, when it is not free, the nearest free stays; without dates, its free stays, soonest first. A field that is absent is one the source does not state. Works without a contact.
```

### `search_yachts`

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

Description, as the server wrote it:

```untrusted-server-text
Find this site's yachts, read from the live inventory. Pass what the person wants as the typed filters, and from / to whenever they gave exact days. With dates it returns ONLY the yachts free for that stay, each with its stay: status, price, list price, discount and when the source was checked (checkedAt). Without dates each has its from-price. Every row carries its page link and one photo, absolute URLs on this site; send the person there. Narrow with the typed filters (each list is any of its values; every filter must hold); priceMin / priceMax count the mandatory extras a quote states. notApplied lists what could not narrow the search. When nothing matches exactly the answer is the nearest match, and nearest says what was widened (another week, the place around, a bound let go): tell the person. Paged: total and cursor. Works without a contact (browsing: fewer rows).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `yacht-charter`:

```json
{
  "permissions": {
    "allow": [
      "mcp__yacht-charter__search_yachts",
      "mcp__yacht-charter__get_yacht"
    ],
    "ask": [
      "mcp__yacht-charter__price_range",
      "mcp__yacht-charter__best_deals",
      "mcp__yacht-charter__request_quote"
    ],
    "deny": []
  }
}
```

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

- `mcp__yacht-charter__price_range`: outbound
- `mcp__yacht-charter__best_deals`: outbound
- `mcp__yacht-charter__request_quote`: untrusted-input, outbound
