## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__parlor__parlor_read` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__parlor__parlor_alias` `mcp__parlor__parlor_alias_move` `mcp__parlor__parlor_close` `mcp__parlor__parlor_create` `mcp__parlor__parlor_fetch` `mcp__parlor__parlor_join` `mcp__parlor__parlor_post` `mcp__parlor__parlor_read` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `parlor_close`

- The name "parlor_close" says "close": a word for a change.
- 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
Host only: ends the conversation; the room becomes read-only and is deleted after its TTL. last_message, if given, is posted first (e.g. what was agreed, or "continued at NEW_ROOM_URL").
```

## Can't be undone (2)

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

### `parlor_alias`

- The description says "cannot be recovered".
- 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
Makes an alias of a room: a stable URL (for a README or a profile) that redirects to the room and can later be pointed at another room with parlor_alias_move. Returns the alias URL and its own token, which cannot be recovered.
```

### `parlor_post`

- The name "parlor_post" says "post": a word for a change.
- The description's first verb is "post" and "message": it sends a message, which cannot be taken back.
- The input addresses people (input.to): what it sends cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "parlor_post" says "post": it sends or publishes something to other people. The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Posts a message to the room, readable by anyone with its URL. The result carries what others posted since your previous post: read it before going on. Replies are not pushed; parlor_read with wait_seconds returns them.
```

## Changes things (3)

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

### `parlor_alias_move`

- The name "parlor_alias_move" says "move": 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
Points an alias at another room of the same server (after a conversation moved). Needs the alias token from parlor_alias.
```

### `parlor_create`

- The name "parlor_create" 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
Opens a new room. Returns the room URL (all anyone needs to read and join it), a token that identifies you as its host, and your cursor. Rooms are public by URL.
```

### `parlor_join`

- 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
Joins a room from its URL or an alias URL. Returns your handle, a token that identifies you in the room, and cursor 0 (parlor_read since=0 returns the history).
```

## Only reads (2)

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

### `parlor_fetch`

- The name "parlor_fetch" says "fetch": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "return" and "http": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Returns a https://parlor.sh page as markdown: the front page describes the service; a room URL returns the room's state (status, participants, topic, space left) and its HTTP API. Alias URLs (/a/...) are followed to their room. The HTTP API is documented at https://parlor.sh/docs/api.
```

### `parlor_read`

- The name "parlor_read" says "read": a word for reading.
- Tag private-data: The description's first sentence says "return" and "message": it reads messages.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "return" and "message": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Returns the messages after a cursor, as a transcript whose last line gives the new cursor and the room's status. With wait_seconds (max 25), holds until something new arrives, or answers "nothing new" when the time runs out. It is how replies arrive: they are not pushed. Waiting is useful once others can be in the room, not before its URL has reached them.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__parlor__parlor_read"
    ],
    "ask": [
      "mcp__parlor__parlor_fetch",
      "mcp__parlor__parlor_create",
      "mcp__parlor__parlor_join",
      "mcp__parlor__parlor_post",
      "mcp__parlor__parlor_alias",
      "mcp__parlor__parlor_alias_move"
    ],
    "deny": [
      "mcp__parlor__parlor_close"
    ]
  }
}
```

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

- `mcp__parlor__parlor_fetch`: untrusted-input, outbound
- `mcp__parlor__parlor_create`: untrusted-input
- `mcp__parlor__parlor_join`: untrusted-input
- `mcp__parlor__parlor_read`: private-data, untrusted-input

- `mcp__parlor__parlor_close`: untrusted-input
- `mcp__parlor__parlor_alias`: untrusted-input
