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 Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- 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
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability62
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1133 tokens (~377/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 Management13
- Stability observed for 4 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
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 supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

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_acquisition_costs Austrian property purchase costs ~369
Calculate the one-off costs of buying residential property in Austria on top of the price (Kaufnebenkosten): real estate transfer tax (Grunderwerbsteuer), land-register court fees, broker commission with a check against the legal maximum, and lawyer/notary contract costs, each with VAT where it applies. Use when someone asks what buying a specific flat or house in Austria costs in total. The JSON lists the cited legal bases and sources once; pass detail "full" for every line item with its calculation and its own citations. Amounts in EUR. Not covered: bank or valuation fees, purchases within the family, exemptions for a primary residence.
| Name | Type | Req | Description |
|---|---|---|---|
| assumptions | object | – | Override default assumptions. Omit to use documented defaults. |
| broker | – | yes | Broker commission, or "none" if the purchase is commission-free (provisionsfrei). |
| detail | string | – | How much of the result to return as JSON. "summary" (default) keeps the key figures, flags, assumptions, limitations and deduplicated citations (about 40% of the size for underwrite_property, 60% for… |
| financing | object | – | Mortgage financing, if any. Adds the court fee for registering the mortgage. |
| purchasePrice | number | yes | Purchase price in EUR (the agreed price for the property), e.g. 249000. |
| valuationDate | string | – | Date whose rules apply, YYYY-MM-DD, usually today or the expected signing date. Defaults to today (Vienna time). Covered: 2025-04-01 to 2027-12-31. |
No output schema declared.
No examples provided.
get_rules Statutory rules and assumptions ~115
List the statutory values the engine uses on a date (tax and fee rates, broker caps, minimum repair reserve, MRG cut-off dates, Richtwerte per state, AfA rates, land shares, income tax brackets), each with legal basis, source URL and the date it was last verified, plus the default assumptions and risk thresholds. Use to cite sources or to explain how a number was calculated.
| Name | Type | Req | Description |
|---|---|---|---|
| date | string | – | Return the rules valid on this date, YYYY-MM-DD. Defaults to today (Vienna time). |
No output schema declared.
No examples provided.
underwrite_property Underwrite an Austrian buy-to-let purchase ~512
Analyse an Austrian residential property as a rental investment: acquisition costs, annuity loan payment, monthly cash flow before and after income tax, gross and net yield, cash-on-cash return, debt cover (DSCR), break-even rent, whether statutory rent caps (MRG) apply and the Richtwert cap, depreciation (AfA) with the legal land share, a 25-year Liebhaberei check, and risk flags. Use when evaluating whether a specific flat or house is a good buy-to-let deal. Inputs in EUR; rents and owner costs are monthly and net of VAT. Pass what you know: missing facts fall back to documented assumptions and are flagged. The JSON is compact by default (key figures, flags, citations); pass detail "full" for every line, the tax years and the rules used. Not covered: rent increases or interest-rate changes over time, tax credits, Richtwert surcharges and deductions (Zuschläge/Abschläge).
| Name | Type | Req | Description |
|---|---|---|---|
| assumptions | object | – | Override default assumptions. Omit to use documented defaults. |
