## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__market-metrics__compare_assets` `mcp__market-metrics__find_assets` `mcp__market-metrics__get_risk_return_metrics` |
| 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 (1)

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

### `rank_assets_by_metric`

- 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
Rank the assets Gale Finance covers by one published metric (return, cagr, volatility, sharpe, sortino, max_drawdown, var_5, es_5, skew, excess_kurtosis), optionally filtered by asset type. Each row carries its value, window dates, and Gale page. Example: "Which crypto had the best Sharpe last year?".
```

## Only reads (4)

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

### `compare_assets`

- The name "compare_assets" says "compare": a word for reading.
- Tag private-data: The description's first sentence says "compare" and "calendar": it reads calendars.

Description, as the server wrote it:

```untrusted-server-text
Compare two assets using Gale Finance's published pair pages: the rolling 1Y compare (default), a calendar-year compare (horizon "2024"), or the long-term scorecard with year-by-year returns (horizon "long_term"). Pairs resolve in either order and keep the cited page's A/B labels. When Gale has no pair page, returns each asset's own metrics side by side and says pair figures are not published. Example: "How has gold performed vs bitcoin historically?".
```

### `find_assets`

- The name "find_assets" says "find": a word for reading.
- Tag private-data: The description's first sentence says "search" and "calendar": it reads calendars.

Description, as the server wrote it:

```untrusted-server-text
Search the assets Gale Finance covers by ticker or name and list, for each, its asset page and the published pair comparisons, calendar-year pages, and long-term scorecards. Omit query to page through all coverage. Example: "Do you cover Hyperliquid?".
```

### `get_downside_risk`

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

Description, as the server wrote it:

```untrusted-server-text
Gale Finance's published downside risk for one asset: daily 5% VaR, expected shortfall, skew and excess kurtosis, the largest drawdown episodes with peak/trough/recovery dates, 1Y max drawdown, and best/worst day from a published compare page. Example: "What are the tail risks for bitcoin?".
```

### `get_risk_return_metrics`

- The name "get_risk_return_metrics" says "get": a word for reading.
- Tag private-data: The description's first sentence says "note": it reads notes.

Description, as the server wrote it:

```untrusted-server-text
Gale Finance's published return, CAGR, volatility, Sharpe, Sortino and max drawdown for one asset (stock, ETF, crypto, or commodity), on its 1Y window and its long window (5Y or since inception), each with a one-line method note and the canonical Gale page to cite. Example: "What's the Sortino ratio of gold?". Computed metrics only; no prices.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__market-metrics__get_risk_return_metrics",
      "mcp__market-metrics__get_downside_risk",
      "mcp__market-metrics__compare_assets",
      "mcp__market-metrics__find_assets"
    ],
    "ask": [
      "mcp__market-metrics__rank_assets_by_metric"
    ],
    "deny": []
  }
}
```

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

- `mcp__market-metrics__get_risk_return_metrics`: private-data
- `mcp__market-metrics__compare_assets`: private-data
- `mcp__market-metrics__find_assets`: private-data

- **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://www.gale.finance/mcp: tools/list returned 5 tools to an anonymous client, including rank_assets_by_metric (write)
