## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `estimate_value`

- 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 what a German address is worth to buy and to rent.

Works for any address, listed or not. The estimate comes from comparable
listings around it, so `confidence` and `sample_size` say how much to trust
it - a thin sample means a wide, weakly supported band.

Returns `estimate` (point values, ranges and €/m² for price and rent) and
`confidence`. A point estimate is absent when too few comparables back it;
the €/m² band and `sample_size` still say what was found. This is a model
output, not an appraisal, and no comparable listing is reproduced in it.
```

## Only reads (2)

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

### `get_listing`

- The name "get_listing" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Details of one listing: facts, Somantic's valuation, and the link to the
original.

No description text: it is the advertiser's, at source_url. A withdrawn
(inactive) listing is not returned: the call fails with "No listing", since
the offer no longer exists.

`image_urls` is always empty: Somantic passes on no photos. They are the
advertiser's, at source_url.
```

### `search_listings`

- The name "search_listings" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search current real-estate listings in Germany, newest first.

Returns listings with facts, Somantic's valuation (somantic_valuation_eur,
price_vs_valuation_pct: negative means priced below it) and source_url, the
original listing on the portal that carries the offer.

`last_seen` is when Somantic last confirmed the offer as online. Listings
no longer confirmed are usually removed from results after 3 days.

One offer is often advertised on several portals at once. Those copies are
collapsed to the newest, so a page can hold fewer than `per_page` listings
and `total` counts the copies rather than the offers.
```
