## 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__airbrake__airbrake_get_deploy` `mcp__airbrake__airbrake_get_group` `mcp__airbrake__airbrake_get_notice_status` `mcp__airbrake__airbrake_list_deploys` `mcp__airbrake__airbrake_list_groups` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__airbrake__airbrake_get_notice_status` `mcp__airbrake__airbrake_list_deploys` `mcp__airbrake__airbrake_list_groups` `mcp__airbrake__airbrake_list_notices` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `airbrake_mute_group`

- The description's first verb is "write": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
WRITE: mute one error group. Airbrake removes it from the default error list and stops ALL notifications for it (email, Slack and other integrations) until it is unmuted. Notices are still recorded. Reversible with airbrake_unmute_group. Airbrake API: PUT /api/v4/projects/{project_id}/groups/{group_id}/muted.
```

## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `airbrake_unmute_group`

- The description's first verb is "write": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
WRITE: unmute one error group, so it is back in the default error list and its notifications resume. Airbrake API: PUT /api/v4/projects/{project_id}/groups/{group_id}/unmuted.
```

## Only reads (11)

Looks things up and changes nothing. Claude Code: allow.

### `airbrake_get_deploy`

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:21:02.729Z, unchanged since 2026-10-22T15:21:02.729Z. 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 | `2` |
| 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 2 tools that change things (1 destructive, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://airbrake.usefulapi.io/mcp: tools/list returned 13 tools to an anonymous client, including airbrake_mute_group (destructive), airbrake_unmute_group (write)
