## 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__booking__find_table_times` |
| 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 `start_appointment_booking` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "start_appointment_booking" 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 "start_appointment_booking" says "start": a word for a change.
```

## Changes things (2)

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

### `start_appointment_booking`

- The name "start_appointment_booking" says "start": 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
Turn a time from find_appointment_times into a link the guest taps to finish booking. This does NOT book anything: it returns a short-lived URL on the venue's own booking page, already opened at that service, that staff member and that exact time, where the guest enters their own name, email and phone and confirms.

Give the guest the `url` and say plainly that the booking is not made until they open it. Never ask the guest for their contact details to pass here; this tool does not take them, and the page collects them directly. Nothing is reserved in the meantime, so a popular time can still go before they tap.
```

### `start_table_booking`

- The name "start_table_booking" says "start": 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
Turn a time from find_table_times into a link the guest taps to finish booking. This does NOT book anything: it returns a short-lived URL on the venue's own booking page, already opened at that party size and that exact sitting, where the guest enters their own details and confirms.

The venue holds the table from the moment the guest opens the link, for about ten minutes, which is what gives them time to fill the form in. Until they open it nothing is held, so give them the `url` promptly and say the table is not theirs until they do.
```

## Only reads (3)

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

### `find_appointment_times`

- The name "find_appointment_times" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free appointment times at one venue for one service, over up to two weeks. For salons, clinics, studios and anywhere a guest books a named service with a provider. Use find_table_times for a restaurant instead.

Needs a service id from get_venue. Each returned time has an `at` label to show the guest and a `slotToken`. The token is the booking handle: it is signed, it expires in about 30 minutes, and it is the only way a time can be booked later. Pass it back exactly as given, never edited, and never reuse one from a different venue. An empty `times` array for a day means that day is genuinely unavailable, not that something failed.
```

### `find_table_times`

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

Description, as the server wrote it:

```untrusted-server-text
Free table times at one restaurant or venue for one party size, over up to two weeks. Use find_appointment_times for a salon or clinic instead.

Each returned time has an `at` label to show the guest and a `slotToken`. The token is the booking handle: it is signed, it expires in about 30 minutes, and it is the only way a time can be booked later. Pass it back exactly as given, never edited, and never reuse one from a different venue. An empty `times` array for a day means the venue has nothing at that party size that day, which usually means closed or fully booked; for a large party the venue may take it by phone even when nothing shows here.
```

### `get_venue`

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

Description, as the server wrote it:

```untrusted-server-text
Read a venue's public booking profile: what it is, where it is, what can be booked, and what time it is THERE right now. Call this first: the other tools need this venue's slug, and appointment searches need a service id from here.

Returns `venueClock`, which is the venue's own current date and time. Every date you ask for later is resolved against `venueClock.today`, not against your own today: the two are routinely different days. Times are given as text on purpose and there is no timezone identifier anywhere in the result, because converting them is how a booking ends up hours off.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__booking__get_venue",
      "mcp__booking__find_appointment_times",
      "mcp__booking__find_table_times"
    ],
    "ask": [
      "mcp__booking__start_appointment_booking",
      "mcp__booking__start_table_booking"
    ],
    "deny": []
  }
}
```

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

- `mcp__booking__find_table_times`: private-data

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://gaplessly.com/api/mcp: tools/list returned 5 tools to an anonymous client, including start_appointment_booking (write), start_table_booking (write)
