## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__all-quiet__allquiet_get_incident_markdown` `mcp__all-quiet__allquiet_list_users` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__all-quiet__allquiet_get_incident_markdown` `mcp__all-quiet__allquiet_list_users` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

annotations: {"readOnlyHint":true}; The name "allquiet_who_is_on_call" says "call": a word for a change.
```

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

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

annotations: {"readOnlyHint":true}; The name "allquiet_on_call_report" says "call": a word for a change.
```


## Deletes or cancels (3)

Removes, cancels or revokes something. Claude Code: deny.

### `allquiet_create_incident`

- The name "allquiet_create_incident" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Creates a new incident on the LIVE account (may trigger alerting/paging). `status` and `severity` are free-form strings the API validates against your account's configuration — common `severity` values include "Warning", "Minor", "Major", "Critical", and `status` reflects the incident lifecycle (e.g. "Open"/"Resolved"); confirm the valid values for your account before calling. All Quiet: POST /v1/incident.
```

### `allquiet_create_on_call_override`

- The name "allquiet_create_on_call_override" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Creates an on-call override for a user on the LIVE account (temporarily changes who is on call). `type` is a free-form override kind and `start`/`end` govern the override window — confirm the valid `type` values for your account. All Quiet: POST /v1/on-call-override.
```

### `allquiet_update_incident`

- The name "allquiet_update_incident" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Applies an operation to an existing LIVE incident: change its severity and/or append an intent (a lifecycle action such as acknowledge/resolve/reopen/snooze — a status transition). At least one of `changeSeverity` or `appendIntent` is required. All Quiet: PATCH /v1/incident/{incidentId}.
```

```untrusted-server-text
Get a summed on-call duration report over a time window, optionally filtered by user/team/escalation tier. All Quiet: GET /v1/on-call-report/sum.

### `allquiet_who_is_on_call`

      "mcp__all-quiet__allquiet_list_incidents",
      "mcp__all-quiet__allquiet_get_incident",
      "mcp__all-quiet__allquiet_get_incident_markdown",
      "mcp__all-quiet__allquiet_list_teams",

    ]
  }
}

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

- `mcp__all-quiet__allquiet_get_incident_markdown`: private-data, untrusted-input
- `mcp__all-quiet__allquiet_list_users`: private-data, untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:21:40.223Z, unchanged since 2026-10-22T15:21:40.223Z. 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` |

- **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 (3 destructive, 2 write). Whether a call also works without credentials was not tested: tools are never called.

https://all-quiet.usefulapi.io/mcp: tools/list returned 11 tools to an anonymous client, including allquiet_create_incident (destructive), allquiet_update_incident (destructive), allquiet_create_on_call_override (destructive), allquiet_who_is_on_call (write), allquiet_on_call_report (write)
