## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `generate_demand_letter`

- The name "generate_demand_letter" says "generate": a word for a change.
- The input carries an amount (input.amount) and a currency, so it moves money.

Description, as the server wrote it:

```untrusted-server-text
Generate the finished demand-letter PDF (formal letter + matching envelope), localized and legally formatted for the jurisdiction. Returns the PDF as a base64 resource. Free, no registration.
```

## Only reads (2)

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

### `list_jurisdictions`

- The name "list_jurisdictions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List every supported country/jurisdiction (code, name, currency, default language) plus the available languages and tones. Call this first to pick a valid jurisdiction + language.
```

### `preview_demand_letter`

- The name "preview_demand_letter" says "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Render the demand letter's text content (title, subject, body paragraphs, amount line, legal reference, closing) as structured JSON, without producing a PDF. Use to review or refine wording before generating.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `final-notice`:

```json
{
  "permissions": {
    "allow": [
      "mcp__final-notice__list_jurisdictions",
      "mcp__final-notice__preview_demand_letter"
    ],
    "ask": [
      "mcp__final-notice__generate_demand_letter"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:04:27.897Z, unchanged since 2026-10-22T15:04:27.897Z. 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` |

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

https://finalnotice.io/mcp: tools/list returned 3 tools to an anonymous client, including generate_demand_letter (irreversible)
