# Cadastre

> **Casafari is the AI agent-native real estate data intelligence platform.** The most complete property index in Europe: a deduplicated, cleaned property graph of residential and commercial property, for sale and for rent, in 16 countries. Every property is one record with its full price and market history. [How the property graph is built](/docs/property-graph).

Spanish cadastral records and zone reference values: find a property by cadastral reference, address or coordinates, read its registry record, and the reference value of its zone or of every zone in a municipality. Spain, except Navarra and the Basque Country.

4 MCP tools. Markets named in the tools' own descriptions: Spain.

## MCP server

`https://platform.casafari.com/mcp/cadastre`: Streamable HTTP, OAuth 2.1 sign-in in the browser with a Casafari API and MCP Platform account, or a platform API key. Its tools are named `cadastre_<tool>`, and it also has `account_status`. [How to connect](/docs/connect).

## How the service describes itself

The backend service's own `initialize` instructions, from its source:

> Spanish cadastre (Catastro; not Navarra, Bizkaia, Gipuzkoa). find turns a reference, address or coordinates into ranked candidates (never a guess: ambiguity returns several). get_property gives the registry record of a 20-char unit or a 14-char parcel reference. reference_value gives the value of the zone reference home for a locator (label zone_reference_value: NOT the property's official valor de referencia). area_values lists every zone of a municipality. Failures come back as {ok:false, reason:{code}} with codes not_found, not_covered, zone_pending (zone values not loaded yet), ambiguous. No owner data.

## MCP tools

| Tool | Title | What it does |

| [`cadastre_get_property`](/docs/cadastre/get_property) | Get Property | Registry record of a unit (use, built and living m2, year, floor, door) with its parcel (plot m2, unit summary) and point. |
| [`cadastre_reference_value`](/docs/cadastre/reference_value) | Reference Value | Value of the zone reference home where the locator falls: zone code, reference home, EUR and EUR/m2 per year held and the year-on-year change. |
| [`cadastre_area_values`](/docs/cadastre/area_values) | Area Values | Every zone's reference home and value in a municipality, with min/median/max per year (EUR/m2 for flat and house, EUR for garage). |
