## Exfil surface

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

| 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__gatwick-transfers__check_flight` `mcp__gatwick-transfers__confirm_booking` `mcp__gatwick-transfers__request_booking` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__gatwick-transfers__confirm_booking` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `confirm_booking`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send the booking request with the code the user received by text. Returns a reference. It is a REQUEST: OrangeRide texts the user to confirm it.
```

## Changes things (4)

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

### `about_orangeride`

- 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
Facts about OrangeRide: area covered, booking notice, payment, Gatwick meeting points, flight tracking, contact details.
```

### `check_flight`

- 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.
- 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
Check a flight landing at Gatwick: airline, origin, scheduled landing (UK time) and terminal. Use for pickups from Gatwick.
```

### `request_booking`

- The name "request_booking" says "request": 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
Start a booking request for a quote the user has agreed to. Texts a 6-digit code to the user's mobile; then ask the user for it and call confirm_booking. Only after reading the trip and fare back to the user.
```

### `suggest_pickup_time`

- 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
For a trip to Gatwick to catch a flight: works out the pickup time (at the airport 2 hours before the flight, plus the drive and 10 minutes spare).
```

## Only reads (3)

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

### `booking_status`

- The name "booking_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Status of one OrangeRide booking. Needs the reference and the mobile number it was booked with.
```

### `find_place`

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

Description, as the server wrote it:

```untrusted-server-text
Look up a UK pickup or drop-off place (street address, postcode, station, hotel). Returns up to 5 matches with ids for get_quote. Not for Gatwick Airport: use the ids gatwick_north or gatwick_south.
```

### `get_quote`

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

Description, as the server wrote it:

```untrusted-server-text
Fixed fare for a trip. With date, time, passengers and suitcases: the exact fare and a quote_id for booking (valid 30 minutes). Without date and time: a typical daytime 'from' price only.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__gatwick-transfers__find_place",
      "mcp__gatwick-transfers__get_quote",
      "mcp__gatwick-transfers__booking_status"
    ],
    "ask": [
      "mcp__gatwick-transfers__about_orangeride",
      "mcp__gatwick-transfers__check_flight",
      "mcp__gatwick-transfers__suggest_pickup_time",
      "mcp__gatwick-transfers__request_booking",
      "mcp__gatwick-transfers__confirm_booking"
    ],
    "deny": []
  }
}
```

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

- `mcp__gatwick-transfers__check_flight`: untrusted-input
- `mcp__gatwick-transfers__request_booking`: untrusted-input
- `mcp__gatwick-transfers__confirm_booking`: untrusted-input, outbound

- **high** 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 (1 irreversible, 4 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.orangeride.co.uk/mcp: tools/list returned 8 tools to an anonymous client, including confirm_booking (irreversible), about_orangeride (write), check_flight (write), suggest_pickup_time (write), request_booking (write)
