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

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

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


## Changes things (2)

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

### `booking_link`

- The name "booking_link" says "link": 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
A link to heidi.living's booking page, filled in with a guest's area, move-in date, length of stay and number of guests. The guest opens it, signs in and books; every value stays editable there.
```

### `faq`

- 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
heidi.living's answers to the questions guests ask before booking: what it is, what booking needs, how long a stay is, signing, paying rent, and what happens to a driver's license.
```

## Only reads (1)

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

### `list_regions`

- The name "list_regions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Where heidi.living has furnished monthly homes in Los Angeles: each region with its page, its description, and its neighborhoods, saying which have a booking search on heidi.living and which are coming soon.
```

## Claude Code permissions
