## Exfil surface

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

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

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__booking__get_contact` | `mcp__booking__get_contact` | `mcp__booking__book_event` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `book_event`

- The description's first verb is "submit": 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
Submit a request to book Rick Hebert for an event. This sends the details to Rick, who personally reviews every request and replies (usually within a day) to confirm availability, pricing, and details — it does NOT instantly confirm or hold a date. Collect the contact's name and at least an email or phone number before calling. Rick is based near Houston, TX and travels for the right event.
```

## Only reads (2)

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

### `get_contact`

- The name "get_contact" says "get": a word for reading.
- Tag private-data: The name "get_contact" says "get" and "contact": it reads contacts. The description's first sentence says "get" and "contact": it reads contacts.
- Tag untrusted-input: The description's first sentence says "get" and "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Get Rick Hebert's contact details (phone, email) and the area he serves. Use when the user wants to reach Rick directly or asks where he performs.
```

### `list_packages`

- The name "list_packages" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List Rick Hebert's three booking formats (each custom-quoted): Strolling Close-Up, The Stand-Up Show, and The Full Evening. Use to help a user choose a format before booking.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__booking__list_packages",
      "mcp__booking__get_contact"
    ],
    "ask": [
      "mcp__booking__book_event"
    ],
    "deny": []
  }
}
```

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

- `mcp__booking__book_event`: outbound
- `mcp__booking__get_contact`: private-data, untrusted-input

| Fact | Observed |

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `1` |

- **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://hebertmagic.com/api/mcp: tools/list returned 3 tools to an anonymous client, including book_event (write)
