## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| 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__bnod-booking__create_booking` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `create_booking`

- The name "create_booking" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Create a booking request for a slot returned by get_available_slots. Only call after the user explicitly confirmed the service, date, time and their name and e-mail. The booking is created as "pending" and the slot is held for 30 minutes; the customer must click the confirmation link sent to their e-mail, otherwise it expires. After that the business's own confirmation policy applies (instant or manual approval). Tell the user to check their inbox.
```

## Only reads (2)

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

### `get_available_slots`

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

Description, as the server wrote it:

```untrusted-server-text
List free appointment start times for one service of a business, per day in the business timezone, with ISO 8601 start/end (including UTC offset) and the team members who can take each slot. Holidays, vacations, working hours and buffers are already applied. Ranges are capped to 14 days. service.questions lists booking questions to ask the user (pass answers to create_booking). Never invent slots: only book times returned here. Flow: search_businesses -> get_available_slots -> confirm service, date, time, team member, name and e-mail with the user -> create_booking. Bookings are only requests until the customer clicks the confirmation link e-mailed to them.
```

### `search_businesses`

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

Description, as the server wrote it:

```untrusted-server-text
Find businesses on bnod (Austrian local services such as hairdressers, barbers, beauty, massage) that accept online bookings. Filter by free text, category, city, a lat/lng radius or a Google Place ID. Returns slugs, addresses with coordinates, services (id, name, duration, price in euro cents) and the profile URL. Flow: search_businesses -> get_available_slots -> confirm service, date, time, team member, name and e-mail with the user -> create_booking. Bookings are only requests until the customer clicks the confirmation link e-mailed to them.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__bnod-booking__search_businesses",
      "mcp__bnod-booking__get_available_slots"
    ],
    "ask": [
      "mcp__bnod-booking__create_booking"
    ],
    "deny": []
  }
}
```

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

- `mcp__bnod-booking__create_booking`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:53:40.266Z, unchanged since 2026-10-22T14:53:40.266Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `1` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://bnod.at/api/mcp: tools/list returned 3 tools to an anonymous client, including create_booking (write)
