allquiet_create_incidentCreates a new incident on the LIVE account (may trigger alerting/paging).No findings
Why it is in this group
- 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
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.
Annotations the server declares
- title: Create incident
- destructiveHint: true

Why it is in this group

- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
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.
Annotations the server declares

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data2: Reads files, mail, messages, databases, secrets, calendars or repositories.; allquiet_get_incident_markdown
allquiet_list_users
Reads text others write2: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; allquiet_get_incident_markdown
allquiet_list_users
Can send data out0: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

Looked at Oct 22, 2026, 15:21 UTC, unchanged since Oct 22, 2026. No credentials were sent and no tool was called. What is looked at.

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
WWW-Authenticate on 401: not observed
resource_metadata in WWW-Authenticate: none
RFC 9728 protected resource metadata: https://all-quiet.usefulapi.io/.well-known/oauth-protected-resource/mcp
Authorization servers: https://all-quiet.usefulapi.io
Legacy HTTP+SSE transport: no
Dynamic client registration: yes
Client ID metadata documents: no

HighThe whole server
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.
Matched text
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)

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as all-quiet. Review it before you use it.

An Atom feed. Works in any feed reader or Slack's RSS app.

Anlyon alternative

5 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
