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_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.

| 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. |

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). |

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).
