## 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__experience-bamfield__get_product` |
| 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** Mentions of other tools or servers in `list_products` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The description contains "every other tool", wording about other tools or servers.

description: "...e, and its published price. Start here: every other tool takes a product id from this list. A co..."
```

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

```untrusted-server-text
The server marks "build_cart_link" 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 "build_cart_link" says "link": a word for a change.
```


## Changes things (5)

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

### `build_cart_link`

- The name "build_cart_link" says "link": 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
Builds the one link that puts the chosen lines in the guest's cart on experiencebamfield.com, and checks it: the lines it opens with, any that would be left out and why, and the totals. Give the guest the url. They review the cart and pay by card; the booking is confirmed the moment they pay. A fishing charter is not carried by the link: it is added from its own page.
```

### `camping_permits`

- 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
Where a camping permit is needed (the Deer Group and the Broken Group Islands), who issues it, what it costs, the longest stay, how long it takes, the campsites that can be applied for, and where the guest applies. The permit is not a line in the cart.
```

### `check_availability`

- 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
Day by day, whether a product is open between two dates, and how many are left where it is counted (boats, parking, charters; for moorage, feet free and the longest boat that fits). For a yes or no on exact dates and a number of units, quote_trip is the shorter road.
```

### `price_cottages`

- 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
Every cottage's price for a stay, whether it is free, and whether it sleeps the party. The figures are before the cleaning fee and taxes: quote_trip gives the all-in total.
```

### `quote_trip`

- 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
The whole basket, the way checkout charges it. Each line: its price and whether it is free for those dates in that number. The basket: the cleaning fee, each tax, the refundable deposits, and totals.dueAtCheckoutCents — the amount the guest's card is charged. Saves nothing and holds nothing. A fishing charter line takes tripType (half-day or full-day).
```

## Only reads (4)

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

### `get_product`

- The name "get_product" says "get": a word for reading.
- Tag private-data: The description's first sentence says "table": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Everything published about one product: description, what is included, amenities, rules, check-in and check-out, rate table, deposit, photographs and its page on the site.
```

### `get_trip_summary`

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

Description, as the server wrote it:

```untrusted-server-text
After the booking. Takes the link a guest made for their assistant on their trip page (or just the key on the end of it) and returns a read-only summary of that one trip: whether it is ready to travel, what needs doing, by what date and who it is waiting on, each booked line with what it came to, and the money — payments received, refunds completed and pending, what is retained, the damage deposit and what is owing. Read it again each time you are asked (freshness.staleAfterSeconds). A fact that is not known is "unknown" and an amount that cannot be stated is null: never read those as yes, no or 0. When money.state is not_reconciled, tell the guest not to pay again on the strength of this and to call the desk. It includes nobody's name or contact details and can change nothing. A link that is wrong, expired or turned off is refused; ask the guest for a new one.
```

### `list_photos`

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

Description, as the server wrote it:

```untrusted-server-text
Photographs of a business and its products, each with a description and an address that can be shown to the guest.
```

### `list_products`

- The name "list_products" says "list": a word for reading.
- Findings: warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
Every product on sale — cottages, kayaks and canoes, parking, moorage, fishing charters — with its id, business, what it holds, how many there are, and its published price. Start here: every other tool takes a product id from this list. A cottage's price depends on the dates (price_cottages).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__experience-bamfield__list_products",
      "mcp__experience-bamfield__get_product",
      "mcp__experience-bamfield__list_photos",
      "mcp__experience-bamfield__get_trip_summary"
    ],
    "ask": [
      "mcp__experience-bamfield__check_availability",
      "mcp__experience-bamfield__price_cottages",
      "mcp__experience-bamfield__quote_trip",
      "mcp__experience-bamfield__build_cart_link",
      "mcp__experience-bamfield__camping_permits"
    ],
    "deny": []
  }
}
```

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

- `mcp__experience-bamfield__get_product`: private-data

- **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 5 tools that change things (5 write). Whether a call also works without credentials was not tested: tools are never called.

https://experiencebamfield.com/mcp: tools/list returned 9 tools to an anonymous client, including check_availability (write), price_cottages (write), quote_trip (write), build_cart_link (write), camping_permits (write)
