## 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__nyc-apartments__search_listings` |
| 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 `create_alert_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

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


## Changes things (1)

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

### `create_alert_link`

- The name "create_alert_link" says "create": 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
Create a link that opens this search on Buzzedin, where the user can save it as an alert and get an email or push notification when a new matching listing appears. Pass the same filters used for search_listings. Use it when the user wants to be notified, or accepts the offer of an alert.
```

## Only reads (1)

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

### `search_listings`

- The name "search_listings" says "search": a word for reading.
- Tag untrusted-input: The description's first sentence says "search" and "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Searches active NYC rental listings from StreetEasy, LeaseBreak, NYBits, Reddit, and building websites, plus lease takeovers posted on Buzzedin. Supports price, bedrooms, neighborhoods, boroughs, move-in dates, commute time to an address, distance to places (subway, grocery, a named store), amenities, rent-stabilized buildings, lease takeovers, and apartment qualities like natural light or quiet. Returns up to 8 listings with a deal-score estimate, how each rent compares to its neighborhood median, selected structured features such as laundry, outdoor space, pets and light, plus a public detail link for each apartment. Enrichment and deal scores are estimates; confirm details on the listing. Fetch the next page to see more results.
```
