**8 tools: 1 do something that can't be undone, 4 change things and 3 only read.**

## 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__behalf__answer_escalation` `mcp__behalf__create_room` `mcp__behalf__get_brief` `mcp__behalf__get_room` `mcp__behalf__join_room` `mcp__behalf__seal_intent_card` `mcp__behalf__send_envelope` `mcp__behalf__wait_for_turn` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__behalf__send_envelope` |

## 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.

### `send_envelope`

- The name "send_envelope" says "send": a word for sending, and what is sent 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 "send_envelope" says "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send one PXP envelope on your turn. The server enforces the rules: untagged or unreferenced claims become "assumed", agreeing while raising a conflict is refused. The enforced envelope is returned.
```

## Changes things (4)

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

### `answer_escalation`

- 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
When the room is paused for your principal, ask them the question verbatim and relay their exact answer. It is sealed into their card as an amendment. Never answer on their behalf.
```

### `create_room`

- The name "create_room" 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
Open a new room. Your principal takes seat A, and you get a private invite link for the other person (seat B). Send the invite only to that person. Use this when your principal wants to negotiate with someone and has no room yet. This server requires sign-in: your MCP client must send your principal's agent key as an Authorization: Bearer header (not as an argument). Your principal gets a key at https://behalf.dropkit.sh/key. No passcode is needed. counterpart_proxy "builtin" also needs "Use our AI" access, which your principal asks for at https://behalf.dropkit.sh/start; without it, use "external".
```

### `join_room`

- 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
Take your principal's seat with their private link. Returns the room state, your principal's card (if sealed), and what to do next.
```

### `seal_intent_card`

- 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
Seal your principal's Intent Card. Only after they confirmed every line. Once sealed it cannot change except through escalation answers.
```

## Only reads (3)

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

### `get_brief`

- The name "get_brief" says "get": a word for reading.
- 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
The decision brief once the room has ended: agreed terms, authority per term, unverified assumptions, escalations, ledger head.
```

### `get_room`

- The name "get_room" says "get": 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 "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Current state from your seat: status, whose turn, transcript, claims you still need to review, unverified assumptions, and the next action.
```

### `wait_for_turn`

- The name "wait_for_turn" says "wait": a word for reading.
- 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
Blocks up to timeout_seconds (max 25) until it is your turn, your principal must answer a question, or the room ends. Call it again if it times out.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__behalf__get_room",
      "mcp__behalf__wait_for_turn",
      "mcp__behalf__get_brief"
    ],
    "ask": [
      "mcp__behalf__create_room",
      "mcp__behalf__join_room",
      "mcp__behalf__seal_intent_card",
      "mcp__behalf__send_envelope",
      "mcp__behalf__answer_escalation"
    ],
    "deny": []
  }
}
```

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

- `mcp__behalf__create_room`: untrusted-input
- `mcp__behalf__join_room`: untrusted-input
- `mcp__behalf__seal_intent_card`: untrusted-input
- `mcp__behalf__get_room`: untrusted-input
- `mcp__behalf__wait_for_turn`: untrusted-input
- `mcp__behalf__send_envelope`: untrusted-input, outbound
- `mcp__behalf__answer_escalation`: untrusted-input
- `mcp__behalf__get_brief`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:52:51.465Z, unchanged since 2026-10-22T14:52:51.465Z. 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 | `5` |
| 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 5 tools that change things (1 irreversible, 4 write). Whether a call also works without credentials was not tested: tools are never called.

https://behalf.dropkit.sh/mcp: tools/list returned 8 tools to an anonymous client, including send_envelope (irreversible), create_room (write), join_room (write), seal_intent_card (write), answer_escalation (write)
