## 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

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "search_figures" says "search": a word for reading.
```


## Changes things (1)

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

### `search_figures`

- The name "search_figures" says "search": a word for reading.
- The description's first verb is "start": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Start here, before get_figure, to find selected figures in Australian retirement rules: rates, amounts, caps, thresholds, ages, periods and dates for the Age Pension and its means tests, superannuation and the Division 293 and 296 taxes, deeming, the Commonwealth Seniors Health Card, aged care and the Home Equity Access Scheme. Searches by keyword, category or both, and returns each match's id and current value. Each current value has an official source, the date it applies from and the date it was last checked; get_figure returns them.
```

## Only reads (3)

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

### `get_figure`

- The name "get_figure" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Gets one Australian retirement figure by an id from search_figures. Returns the value recorded for a date (as_at, or today in Sydney), the date it applies from and what that date means, conditions, exceptions, the official source by name, the date last checked and a citation of the figure's Retirement Wealth page. Values set by law but not yet in force are listed under upcoming. No value is returned for a date before the earliest recorded value, after today, or from the start of a value set by law not yet confirmed in force.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
Shows which areas of Australian retirement rules the figures cover: the categories, such as Age Pension, super caps and aged care, with each one's id for search_figures and its number of figures. Also returns the data release, the newest and the oldest date on which a figure was last checked against its source, the scope statement, and links to the documentation and the JSON files.
```

### `list_changes`

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

Description, as the server wrote it:

```untrusted-server-text
Lists what this site has changed in its published Australian retirement figures since a date, such as new or corrected values, earlier values added and figures added or renamed. Newest first. since filters on recorded_on, the date this site recorded the change, in Sydney. effective_from is the date the changed value applies from, where the change has one. A value can be recorded long after it began to apply.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__data__get_figure",
      "mcp__data__list_changes",
      "mcp__data__list_categories"
    ],
    "ask": [
      "mcp__data__search_figures"
    ],
    "deny": []
  }
}
```

- **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://retirementwealth.com.au/mcp: tools/list returned 4 tools to an anonymous client, including search_figures (write)
