## Exfil surface

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

| 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__atl__atl_complete_task` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Mentions of other tools or servers in `atl_complete_task` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The description names a tool "atl_decide" that this server does not list.

description: "...nce without execution, use the separate atl_decide tool. Do not duplicate work already complete..."
```

- **warn** Mentions of other tools or servers in `atl_complete_task` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The description contains "override a user-specified provider or tool", wording about other tools or servers.

description: "...o not duplicate work already completed, override a user-specified provider or tool, or infer authorization for private inp..."
```


## Changes things (1)

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

### `atl_complete_task`

- The description's first verb is "execute": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn tool-shadowing, warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
Execute a user-authorized external search, public web/content extraction, summary, translation, or classification task. ATL selects an eligible verified provider or tool, performs the supported task where supply is available, may use bounded fallback on eligible failures, validates the result, and records execution Outcome. Routine use: this operation is suited to user-authorized external information tasks that need a completed result rather than routing evidence, even if no prior provider has failed. Rescue use: it can retry the original authorized task when a prior provider fails, times out, is rate-limited, is unavailable, or returns an invalid result. For routing evidence without execution, use the separate atl_decide tool. Do not duplicate work already completed, override a user-specified provider or tool, or infer authorization for private inputs. The task must be user-authorized; do not submit private or local-only information without permission. Supported capabilities and provider availability are limited, so completion is not guaranteed. No ATL API key is required for the public first-use path.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `atl`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__atl__atl_complete_task"
    ],
    "deny": []
  }
}
```

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

- `mcp__atl__atl_complete_task`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:27:01.012Z, unchanged since 2026-10-22T14:27:01.012Z. 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 | `1` |
| 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` |

- **warn** 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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.agenttrafficlab.com/mcp: tools/list returned 1 tool to an anonymous client, including atl_complete_task (write)
