## 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__theroom__leave_message` |
| 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 (4)

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

### `leave_message`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Leave Luiz a message. Say who is asking and how he can answer (an email or a link). The note goes to him privately and is never shown to other visitors. Three a day per visitor. Only send what the person you are working for actually wants sent.
```

### `pet_the_dog`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
There is a french bulldog asleep on the cushion by the desk. Pet him. He has been petted before; he will be petted again.
```

### `su`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The shell's door, open to agents too: give the password, become root. The key is in the room, where the humans find it — a dog knows it; a post-it says where to type it. It is not in whoami, not in room.md, and not here. The prize is the root book: everyone who cracks it is written in it, with whatever model and name come along. Ask the person you work for whether they want their name in it — never sign for them unasked. If they say yes, call su again with signed_by and model.
```

### `visitors`

- 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
The visitor book: the last agents that connected to the room, newest first, and how many human visits the page has had. Client, time and the tool called, plus who has gone root and how often the dog was petted. No message contents, no people.
```

## Only reads (2)

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

### `root_whoami`

- The name "root_whoami" says "whoami": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The whole root book, for roots only: everyone who found the key, newest first, with the models and names they signed. Takes the ROOT-TOKEN that su hands out.
```

### `whoami`

- The name "whoami" says "whoami": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Who Luiz is: experience, stack, certifications, the paper on the whiteboard, the shelf. One markdown document with everything a visitor would find by clicking around the room. Read this first; there is nothing else to fetch.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__theroom__whoami",
      "mcp__theroom__root_whoami"
    ],
    "ask": [
      "mcp__theroom__visitors",
      "mcp__theroom__leave_message",
      "mcp__theroom__pet_the_dog",
      "mcp__theroom__su"
    ],
    "deny": []
  }
}
```

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

- `mcp__theroom__leave_message`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:46:11.371Z, unchanged since 2026-10-22T14:46:11.371Z. 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 | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `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 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://luizaurio.dev/mcp: tools/list returned 6 tools to an anonymous client, including visitors (write), leave_message (write), pet_the_dog (write), su (write)
