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. How we score → Why this is hard to score →
Endpoint Security89
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability54
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management7
- Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
estimate_value Estimate value ~406
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.
| Name | Type | Req | Description |
|---|---|---|---|
| city | string | yes | 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 | yes | Living area in m². |
| postcode | string | yes | 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 | yes | 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. |
Structured output declared, but exposes no named fields.
No examples provided.
get_listing Get listing ~129
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.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | The listing id from search_listings. |
| property | – | – | "wohnung" or "haus" if known; both are tried otherwise. |
Structured output declared, but exposes no named fields.
No examples provided.
search_listings Search listings ~606
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |

| year_min | – | – | Built in or after this year. |
