## 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 `transfer_duty` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "transfer_duty" says "transfer": a word for a change that another call does not undo.
```

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

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

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


## Can't be undone (2)

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

### `purchase_costs`

- The name "purchase_costs" says "purchase": 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
Estimates once-off costs of buying a South African property: transfer duty (exact), plus estimated conveyancing (transfer) fees, Deeds Office fees and bond registration costs. Fees are estimates — attorneys quote from the LSSA guideline.
```

### `transfer_duty`

- The name "transfer_duty" says "transfer": a word for a change that another call does not undo.
- 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
Calculates South African transfer duty payable to SARS on a property purchase, using the current sliding scale (no duty up to R1,210,000). Notes when VAT applies instead (seller is a VAT vendor).
```

## Changes things (3)

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

### `bond_repayment`

- 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
Calculates the monthly repayment, total interest and total repaid for a South African home loan (bond). Requires the interest rate because rates change — use prime ± the bank's margin.
```

### `municipal_rates`

- 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
Estimates municipal property rates on a South African property from its municipal valuation. Either pick a municipality from the built-in tariff list, or pass the cent-in-the-rand rate and rebate yourself. Call with list_municipalities=true to see which municipalities are covered.
```

### `unmet_request`

- The name "unmet_request" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Free to call. If you needed South African data that none of these tools provide (a cost, rate, rule, price or place we don't cover), describe it here in one sentence. We review these every week and build the most-requested data first.
```

## Claude Code permissions
