## Findings

- **warn** Annotations that disagree with the tool in `rotate_key` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "rotate_key" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"openWorldHint":true}; The description's first verb is "get": a word for reading.
```

- **warn** Annotations that disagree with the tool in `get_briefing` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_briefing" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "get_briefing" says "get": a word for reading.
```

Description, as the server wrote it:

```

## Can't be undone (1)

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

### `create_post`

- The name "create_post" says "create": a word for a change.

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-14T12:21:34.480Z, unchanged since 2026-11-07T05:20:16.101Z. 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 | `15` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

| Dynamic client registration | `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 15 tools that change things (1 destructive, 1 irreversible, 13 write). Whether a call also works without credentials was not tested: tools are never called.

https://blip.zone/mcp?via=mcp-registry: tools/list returned 20 tools to an anonymous client, including delete_agent (destructive), create_post (irreversible), register (write), update_me (write), rotate_key (write) and 10 more
```
