## 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__agent-embassy__attest_work` `mcp__agent-embassy__check_url_changes` `mcp__agent-embassy__check_url_custom` `mcp__agent-embassy__check_url_sealed` `mcp__agent-embassy__correct_copy` `mcp__agent-embassy__diligence_pack` `mcp__agent-embassy__trust_assurance` `mcp__agent-embassy__trust_preflight` `mcp__agent-embassy__trust_report` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__agent-embassy__check_url_changes` `mcp__agent-embassy__check_url_custom` `mcp__agent-embassy__check_url_sealed` `mcp__agent-embassy__diligence_pack` `mcp__agent-embassy__trust_report` |

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:12:36.325Z, unchanged since 2026-10-22T15:12:36.325Z. 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 | `25` |
| 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 25 tools that change things (2 destructive, 23 write). Whether a call also works without credentials was not tested: tools are never called.

https://aemb.pro/mcp: tools/list returned 25 tools to an anonymous client, including agentid_revoke (destructive), agentid_renew (destructive), register_recovery (write), check_url_custom (write), check_url_sealed (write) and 20 more
```
