## 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.


## Changes things (3)

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

### `keepup_users_net_worth`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
How KeepUp users compare: net worth at the 25th, 50th, 75th and 90th percentiles and the asset class most of them are led by, worldwide or in one country, optionally within an age band. Rounded group figures over users on KeepUp's public leaderboard (groups of five or more), never an individual. For a whole country's population, use net_worth_percentile.
```

### `net_worth_by_age`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Household net worth by age of the household head in a country: the median and the top 10% and top 1% cutoffs for each age group (under 35, 35 to 44 … 75 or older). Pass an age to single out its group. Use for 'what is the average net worth at 30', 'top 1% net worth at 40 in the US' or 'median net worth by age in Germany'. US medians are the Federal Reserve's; other countries are labeled estimates.
```

### `net_worth_percentile`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Given a household net worth in USD and a country (and optionally the age of the household head), return the wealth percentile it falls in and the 'top X%'. Answers questions like 'what percentile is a $500k net worth in Germany', 'is $1M a lot in Japan' or 'is $200k good at 30 in the US'. Public aggregate data, no personal or account information.
```

## Only reads (2)

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

### `country_net_worth_thresholds`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the household net worth (USD) needed to reach the median and the top 25%, 10%, 5%, and 1% in a given country. Use for 'what net worth is top 1% in the UK' or to build a wealth-distribution table. Public data.
```

### `list_supported_countries`

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

Description, as the server wrote it:

```untrusted-server-text
List every country KeepUp has wealth-distribution data for, with whether it has full survey breakpoints (higher precision at the tails). Call this to discover valid country codes.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__keepup__country_net_worth_thresholds",
      "mcp__keepup__list_supported_countries"
    ],
    "ask": [
      "mcp__keepup__net_worth_percentile",
      "mcp__keepup__net_worth_by_age",
      "mcp__keepup__keepup_users_net_worth"
    ],
    "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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.keepup.finance/mcp/connector: tools/list returned 5 tools to an anonymous client, including net_worth_percentile (write), net_worth_by_age (write), keepup_users_net_worth (write)
