| Group | Class | Tools | Claude Code |

## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__secret-santa__show_secret_santa_status` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__secret-santa__create_secret_santa` `mcp__secret-santa__redraw_secret_santa` |
| 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.


## Deletes or cancels (1)

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

### `redraw_secret_santa`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
- 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
Use this when the organizer wants a new random draw for an existing Secret Santa, for example because they saw an assignment by mistake. Takes the organizer link. Works only while nobody has opened a private link; it replaces the old draw with the same rules, keeps the same private links and keeps wishlists. Does not add or remove people (make a new Secret Santa for that).
```

## Changes things (1)

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

### `create_secret_santa`

- The name "create_secret_santa" 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
Use this when the user wants to draw names for a Secret Santa or holiday gift exchange and give each person a private link. Takes 3 to 60 names, optional couples or households who must not draw each other, one-way exclusions (for example last year's match), a budget, an exchange date and a note. Publishes a hosted page: each private link shows one person whom they buy for, the budget, the date and the match's wishlist, and each person can add their own wishlist. Returns one private link per person and an organizer link; the draw itself is not returned. Explains why when no draw is possible. Does not send emails or texts. Do not use for White Elephant games or for picking one winner.
```

## Only reads (1)

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

### `show_secret_santa_status`

- The name "show_secret_santa_status" says "show": a word for reading.
- Tag private-data: The name "show_secret_santa_status" says "show" and "secret": it reads secrets. The description's first sentence says "secret": it reads secrets.

Description, as the server wrote it:

```untrusted-server-text
Use this when the organizer asks who has opened their Secret Santa link, who added a wishlist, or wants the private links again. Takes the organizer link (it contains /m/). Returns each person's link, whether and when it was first opened, and whether they added a wishlist. Does not return who buys for whom. Does not change anything. Does not work with a person's private link.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__secret-santa__show_secret_santa_status"
    ],
    "ask": [
      "mcp__secret-santa__create_secret_santa"
    ],
    "deny": [
      "mcp__secret-santa__redraw_secret_santa"
    ]
  }
}
```

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

- `mcp__secret-santa__create_secret_santa`: untrusted-input
- `mcp__secret-santa__show_secret_santa_status`: private-data
- `mcp__secret-santa__redraw_secret_santa`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-08T06:23:15.378Z, unchanged since 2026-11-08T06:23:15.378Z. 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 | `2` |
| 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` |

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

https://secret-santa.zovo.one/mcp: tools/list returned 3 tools to an anonymous client, including redraw_secret_santa (destructive), create_secret_santa (write)
```
