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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "convert_hourly_to_salary" says "convert": a word for a change.
```


## Changes things (2)

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

### `calculate_paycheck`

- 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
Estimate 2026 take-home pay for one paycheck in California, New York, Illinois, Texas, or Florida. Federal income tax, Social Security, Medicare, and that state's withholding use the same figures as auracalcs.com. Returns the paycheck lines, a link to the matching page, the publications and the date they were checked, and a disclaimer. Estimate only.
```

### `convert_hourly_to_salary`

- The name "convert_hourly_to_salary" says "convert": a word for a change.
- 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
Convert an hourly wage into gross annual, monthly, semimonthly, biweekly, weekly, and daily pay, including overtime. Uses the same formula as the AuraCalcs hourly to salary page. This is gross pay before tax. Estimate only.
```
