## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 54/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1197 tokens (~399/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (3)

### `search_listings` (~606 tokens)

Search listings

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.

Input parameters:

- `energy_class`: Energy efficiency classes, e.g. "A+,A,B".
- `exclude_erbbaurecht` (boolean): Leave out leasehold (Erbbaurecht) properties.
- `exclude_foreclosures` (boolean): Leave out foreclosure auctions (Zwangsversteigerungen).
- `features`: Required amenities. "new_building" keeps only new builds (Neubau, Erstbezug, or built within the last 3 years).
- `page` (integer): Result page, starting at 1.
- `per_page` (integer): Results per page, at most 50.
- `price_below_market`: Only listings priced below Somantic's valuation.
- `price_change`: Only listings whose price changed while listed: "reduced", "increased" or "any".
- `price_max`: Maximum price in EUR; monthly cold rent when transaction is "mieten".
- `price_min`: Minimum price in EUR; monthly cold rent when transaction is "mieten".
- `price_per_sqm_max`: Maximum price per m² in EUR; cold rent per m² when transaction is "mieten".
- `price_per_sqm_min`: Minimum price per m² in EUR; cold rent per m² when transaction is "mieten".
- `property` (string): "wohnung" (apartment) or "haus" (house).
- `q`: Where — a city ("München", "Frankfurt am Main") or a postcode ("80331").
- `renovation_needed`: Only listings that need renovation (renovierungsbedürftig).
- `roi_min`: Minimum gross rental yield in percent, e.g. 5 for 5 %. Purchases only.
- `rooms_max`: Maximum number of rooms.
- `rooms_min`: Minimum number of rooms (German count, e.g. 2.5).
- `size_max`: Maximum living space in m².
- `size_min`: Minimum living space in m².
- `transaction` (string): "kaufen" to buy, "mieten" to rent.
- `vacant`: Only listings that are vacant (bezugsfrei).
- `year_max`: Built before this year.
- `year_min`: Built in or after this year.

### `get_listing` (~129 tokens)

Get listing

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.

Input parameters:

- `id` (string, required): The listing id from search_listings.
- `property`: "wohnung" or "haus" if known; both are tried otherwise.

### `estimate_value` (~406 tokens)

Estimate value

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.

Input parameters:

- `city` (string, required): City name, e.g. "München".
- `features`: Equipment the property has. Only what it *has* - a feature left out is treated as unknown, not as absent.
- `floor`: Floor the flat is on.
- `living_space_sqm` (number, required): Living area in m².
- `postcode` (string, required): Five-digit German postcode, e.g. "80331".
- `property` (string): "wohnung" (apartment) or "haus" (house).
- `property_type`: A narrower type such as "reihenhaus" or "etagenwohnung"; an unknown value is refused with the list of accepted ones.
- `rented`: True values it as sold with a sitting tenant, False as sold bezugsfrei - in Germany the same flat is worth markedly less with one. Leave it out unless you know which it is.
- `rooms`: Number of rooms (German count, e.g. 2.5). Improves the estimate.
- `street` (string, required): Street and house number, e.g. "Marienplatz 1". Required: without it the answer would silently describe the middle of the postcode.
- `year_built`: Year of construction. Improves the estimate.
