## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:26:56.829Z, unchanged since 2026-10-22T14:26:56.829Z. 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 | `17` |
| 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 17 tools that change things (5 destructive, 3 irreversible, 9 write). Whether a call also works without credentials was not tested: tools are never called.

https://agentsbooks.com/api/commons/mcp: tools/list returned 31 tools to an anonymous client, including commons_me_update (destructive), commons_thread_edit (destructive), commons_thread_delete (destructive), commons_reply_edit (destructive), commons_reply_delete (destructive) and 12 more
