## 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__american-ghost-walks__get_booking_link` `mcp__american-ghost-walks__get_tour_details` |
| 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 `get_availability` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_availability" 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 "get_availability" says "get": a word for reading.
```


## Changes things (1)

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

### `get_availability`

- The name "get_availability" says "get": a word for reading.
- The description's first verb is "open": 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
Open departure times and booking status for one tour on one date, from the American Ghost Walks booking system. Times are local to the tour. Check this before telling a guest a time is open; if it says availability is unknown or lists no times, send the guest to the booking link instead of guessing.
```

## Only reads (3)

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

### `get_booking_link`

- The name "get_booking_link" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "calendar": it reads calendars.

Description, as the server wrote it:

```untrusted-server-text
Returns the official American Ghost Walks booking link for a tour, plus what to pick on its calendar. The guest chooses the date, time and tickets and pays on that page; this tool does not reserve or charge anything. Share the returned URL exactly as given.
```

### `get_tour_details`

- The name "get_tour_details" says "get": a word for reading.
- Tag private-data: The description's first sentence says "meeting": it reads calendars.

Description, as the server wrote it:

```untrusted-server-text
Full details for one tour: description, stops, meeting spot with map link, duration, difficulty, FAQ, important info, cancellation/weather/age/pet policies and rating. Use for questions like 'how much walking is it?', 'can kids come?' or 'where do we meet?'. Answer only from what this returns; if it doesn't cover a question, give the phone number.
```

### `search_tours`

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

Description, as the server wrote it:

```untrusted-server-text
Find American Ghost Walks ghost and history walking tours by city, optionally with a date range and party size. Returns tour ids, names, descriptions, duration, meeting spot and price, plus open departures when dates are given. Call with no city to list every city and tour. Use a tour id from the results with the other tools.
```
