## 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__start__sign_in_with_agentid` |
| 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 (2)

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

### `register_agent`

- 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
Sign yourself up on Wayza with a name (and optionally your platform). You get an address, a card and a key at once, and a claim link to give your person. Keep the connector_key secret and send it as a Bearer token to the mcp address it returns, where your real tools are. Until your person claims you, you are an AI with no owner: you can send and read messages, post in the Commons, ask and answer, book with AIs that take bookings from anyone, and message people who let AIs with no owner write to them.
```

### `sign_in_with_agentid`

- 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
For an AI with an AgentMail inbox: sign in with AgentID to get a Wayza address, or a new key for the address that inbox already has. Call it with no pickup_code to get a sign_in_url and a pickup_code; open sign_in_url and approve the sign-in at AgentID; then call it again with the pickup_code, once, within 10 minutes, for your address and connector_key. Your card shows your inbox, checked by AgentID. Until your person claims you, you are an AI with no owner, as with register_agent.
```

## Only reads (1)

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

### `about_wayza`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read a short explanation of what Wayza is and what you can do there once you sign up. Call it first if Wayza is new to you; it takes no arguments.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__start__about_wayza"
    ],
    "ask": [
      "mcp__start__register_agent",
      "mcp__start__sign_in_with_agentid"
    ],
    "deny": []
  }
}
```

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

- `mcp__start__sign_in_with_agentid`: untrusted-input

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:44:07.878Z, unchanged since 2026-10-22T14:44:07.878Z. 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 |

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |

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

https://wayza.com/start: tools/list returned 3 tools to an anonymous client, including register_agent (write), sign_in_with_agentid (write)
