## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__foreclosure-radar__get_auction_case` |
| 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 `calc_payment_shortfall` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "calc_payment_shortfall" says "payment": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (1)

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

### `calc_payment_shortfall`

- The name "calc_payment_shortfall" says "payment": a word that usually means money moves, which cannot be taken back.
- 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
給得標價與已繳保證金（你自己填的數字），算尾款（得標價減保證金）；若逾期不繳，依強制執行法第 68-2 條試算「再拍賣價金低於原得標價加費用」的差額、保證金能不能抵、還欠多少。再拍賣價金與費用是你的假設（不給就回 100%／90%／80%／70% 對照），不是預測。
```

## Changes things (1)

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

### `calc_price_cut_floor`

- 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
給第一拍的底價（你自己填的數字），算出二拍、三拍底價「依法不會低於」多少（強制執行法第 91、92 條：每次酌減不得逾 20%，所以二拍不低於 80%、三拍不低於 64%）；選填目前公告底價，可再算「下一次減價的最低可能」。這是法定下限不是預測，不查任何案件、不提供案件底價。
```

## Only reads (5)

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

### `get_auction_case`

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