## 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

No check matched anything in these tool definitions.


## Changes things (5)

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

### `realistimo_deal_cost`

- 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
What a property purchase or sale in Bulgaria costs on top of the price: notary fee, registration, the municipality's local acquisition tax, broker commission, certificates, the seller's income tax, and — with a mortgage — the bank's fees, the loan and the monthly payment. For an apartment with a place and an area it adds the likely rent, yield and payback. Use for „колко струва покупката/продажбата", „такси при покупка на имот", „нотариални такси", „местен данък", „колко пари ми трябват за апартамент за 120 000 евро". Amounts in euros.
```

### `realistimo_estimate_price`

- 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
An estimate of what a property in an oblast capital (София, Пловдив, Варна, Бургас, …) or one of its квартали would ask on sale and on rent: the median asking price per m² of Realistimo's live listings there — the figures of its price statistics pages — times the area. With askingPrice it also says where that price sits among the listings' prices per m² (below the cheapest 10%, under or over the median, above the dearest 10%). Use for „колко струва апартаментът ми", „колко наем да искам", „скъпа ли е тази обява". Not an appraisal.
```

### `realistimo_market_index`

- 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
„Индекс Realistimo": the monthly edition of average asking prices per m² in Bulgaria's largest cities, with the change on the previous month (and on the year where the edition shows it) and the квартали whose prices rose and fell most. Use for „как се движат цените на имотите", „пазарен индекс", „цени на имоти за септември". The latest edition unless a month is asked for.
```

### `realistimo_market_stats`

- 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
Asking-price statistics from Realistimo's live listings for an oblast capital (София, Пловдив, Варна, Бургас, …) or one of its квартали: price and price per m² (P10–P90, median), how many listings, the share with a price cut, the city's 12-month trend per m², the gross rental yield for apartments, and the city's quarterly count of registered sales and mortgages. Use for „колко струва квадратен метър в Лозенец", „цени на апартаменти във Варна", „наеми в Пловдив", „доходност от наем". Prices in euros.
```

### `realistimo_neighbourhood_profile`

- 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
A profile of a place in Bulgaria from Realistimo: its location page's own description, how many properties are listed for sale and for rent, the median asking price and rental yield where Realistimo publishes them, and — for a квартал of Sofia — the metro stations and kindergartens near it. Use for „какъв квартал е Лозенец", „добре ли е да се живее в Младост", „какво има в Банско", „кой квартал да избера".
```
