## 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 (1)

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

### `rank_funds`

- 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
Sort 2 to 10 funds by up to three published facts: ongoing charge, US share, pairwise overlap and holdings count. Rows follow the criteria in order. A missing fact sorts last and stays null; it is never estimated. Rates are decimal fractions (0.07 = 7%). Analysis based on published fund data. Returns checkUrl: a shareable link to the same result.
```

## Only reads (3)

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

### `compare_funds`

- The name "compare_funds" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Analyze two ETFs as a 50/50 portfolio, with overlap and issuer facts including dated ongoing charges side by side, and each fund's own region and sector exposure. Identify each side with exactly one ISIN or ticker; a ticker can be ambiguous across exchanges. Unknown facts remain null. Returns checkUrl: a shareable link to the same result.
```

### `search_funds`

- The name "search_funds" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the published instrument catalogue by name, ISIN or ticker; includes currency and listing identifiers. Returns checkUrl: a shareable link to the same result.
```

### `xray_portfolio`

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

Description, as the server wrote it:

```untrusted-server-text
Analyze free-preview ETF overlap/concentration findings, known ongoing charges and regional/sector exposures from published evidence. Identify each holding with exactly one ISIN or ticker; a ticker can be ambiguous across exchanges. Use positive relative weights, values in one base currency, or omit all amounts for equal weights. Never mix weights and values. At most 10 distinct tickers per call. Dates, coverage and all data gaps accompany the result. Returns checkUrl: a shareable link to the same result.
```
