## Exfil surface

2 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__bop__request_booking`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__bop__get_business` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__bop__complete_booking` `mcp__bop__get_booking_link` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__bop__request_booking` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__bop__get_business` | `mcp__bop__complete_booking` | `mcp__bop__request_booking` |

```

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

```untrusted-server-text
The server marks "get_booking_link" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "get_booking_link" says "get": a word for reading.
```


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_booking`

- The name "cancel_booking" says "cancel": a word for removing or ending something.
- The description says "cannot be undone".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Cancel a confirmed, pending or awaiting_payment booking made with request_booking, when the customer asks to. Frees the place for others and cannot be undone; a booking paid online is refunded minus the card processing fee Stripe charged and BOP's fee (5.5% + NT$10). Online cancellation closes at the business's cutoff (online_cancellation in get_business; 120 minutes before the start time unless the business sets a longer one).
```

### `modify_booking`

- The name "modify_booking" says "modify": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Change the slot or quantity of a pending, awaiting_payment or confirmed booking, when the customer asks to. Replaces the booking's time or quantity and frees the old place. Use a slot value from get_availability. A booking paid online can change its slot but not its quantity (cancel and rebook instead). Changes close at the same cutoff as online cancellation.
```

## Can't be undone (1)

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

### `complete_booking`

- The description's first verb is "pay": a word that usually means money moves, which cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info credentials-mention, info credentials-mention, info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Pay for a booking whose status is awaiting_payment, with a payment credential the customer approved for the booking's amount and currency. payment.handler_id must come from the booking's payment_handlers ("stripe_payments"), and credential is {type: "stripe_payment_token", token: "spt_…"}: a Stripe shared payment token issued to the handler's business_profile. Charges the customer once (repeating the call does not charge twice). Returns the booking (confirmed, or pending if the business confirms it) and the payment result; if payment.status is requires_action, open payment.redirect_url for the customer and call again with the same credential.
```

## Changes things (2)

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

### `get_booking_link`

- The name "get_booking_link" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
For businesses whose booking_mode is external_link: get a link to the business's own booking page for one service. The click is counted for the business. Booking and payment happen on that page.
```

### `request_booking`

- The name "request_booking" says "request": a word for a change.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Create a booking for one open slot on behalf of the customer, after the customer has agreed to the service, time, quantity and contact details. Sends the customer's name, phone and email to the business. The result is either 'confirmed' or 'pending' (waiting for the business to confirm). Payment is at the venue, unless the business takes online payment (payment in get_business): then the status is 'awaiting_payment' with amount, currency, expires_at and payment_handlers, and the place is held until expires_at for complete_booking. Returns booking_id and a one-time status_token for get_booking_status, complete_booking, modify_booking and cancel_booking. Repeating the call for the same contact details, service and slot is rejected as a duplicate.
```

### `get_availability`

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

```

### `get_booking_status`

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

```

### `get_business`

```

### `search_businesses`

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

```
