Catastro GPS MCP server

Official cadastral parcels for AI agents from 29 European countries (including the Basque Country and Navarre foral cadastres), with one API key: by cadastral reference in 27, by coordinates in all 29. In Croatia (ARKOD agricultural parcels), Sweden (agricultural blocks) and Scotland (by coordinates) the source is not a full cadastre.

Ask your agent for a parcel by its cadastral reference, by a point on the map or by a postal address. It gets back the reference, location, area, land use and the parcel outline; it can list every dwelling of a Spanish building, read relief, protected areas, climate normals and satellite ground motion, estimate solar and agricultural potential, read aggregated market prices, and score and compare parcels.

• 29 countries, one call shape. ES, PT, FR, IT, DE, PL, NL, CH... and the two Spanish foral cadastres (PV, NA) that the central Catastro does not serve.
• The country is optional. It is detected from the reference format or from the point. When bare digits fit several countries the API says so (CNV_AMBIGUOUS) and resolve_reference tells you which ones, for free.
• Address search in 27 countries. "Calle Gran Via 31, Madrid", "8 boulevard du Port, Amiens" or "Damrak 1, 1012 LG Amsterdam" become ranked parcels.
• Buildings, not only plots. get_units lists every dwelling, shop and garage of a Spanish building with floor, door, area and participation coefficient.
• Your quota in every answer. Each result carries the monthly quota left, the prepaid balance and the per-minute headroom.
• Free tier for good. 250 calls a month at no cost, no card. Failed lookups are not charged.

Quota, prepaid balance and limits

• Only successful answers with data spend quota: a not found, a validation error, CNV_COVERAGE, CNV_AMBIGUOUS, a 5xx and an answer without data (available: false) are free. resolve_reference never spends.
• Each successful call costs 1 unit, except get_units (one unit per unit served in the page, minimum 1) and compare_parcels (one per parcel found).
• Every result carries a quota object read from that same response: remaining, limit, resets_at, plan, and when they apply prepaid_overage, prepaid_balance_eur, overage_units_left, per_minute_remaining, and on get_units with a contract per-finca cap finca_cap / finca_cap_used.
• When the monthly quota runs out the API does not cut you off if you have prepaid balance: each extra unit is paid from it (top up at parcelgps.com/app/developer). With the quota used up and no balance the call fails with KEY_AUTH_004 (HTTP 429, never 402) and the error says whether to top up or upgrade, and when the quota resets.
• A separate per-minute limit depends on the plan (Free 10, Developer 60, Startup 120, Growth 300 calls per minute; a global per-IP guard also applies). Going over it answers KEY_RATE_002 with the seconds to wait.

What the market, score and history tools can and cannot tell

• get_market_data has numbers only where an official source gives them: France (DVF recorded sales: average €/m², number of sales, last sale date, estimated value), Italy (OMI zone values from the Agenzia delle Entrate) and Germany (official Bodenrichtwert land value per m², North Rhine-Westphalia only; elsewhere in Germany it answers available: false). In Spain and Portugal it answers with a note and no figures: there is no per-parcel price source yet.
• get_investment_score combines what the API can gather for the parcel: solar potential and agricultural use everywhere it answers, market prices only in France, Italy and Germany (NRW). Accessibility and risk are not computed yet and come back as not_available, so the score is relative to the factors that were available. You get the score, the rating and qualitative factor levels, never the weights.
• get_value_history starts the first time anyone looks the parcel up through Catastro GPS (at most one snapshot every 30 days). A parcel nobody has queried returns an empty list. It records area and land use; the official cadastral value is not recorded yet, so cadastral_value_eur is always null and change_pct is the change in area.
• compare_parcels fills area, land use and municipality only for Spanish parcels; for Portugal, France, Italy and Germany it returns the location, solar, agriculture and score. It does not include market prices. A parcel that is not found comes back with an error and the others are still compared.

Coverage

What each code answers today (measured against production on 1 October 2026). "Partial" means the official source does not cover the whole territory.

Code	Country / region	By reference	By coordinates	Address search	Notes
ES	Spain (central Catastro)	yes	yes	yes	Buildings and dwellings with get_units
PV	Basque Country (Araba, Bizkaia, Gipuzkoa)	yes	yes	with country: ES	Foral cadastres; get_units without participation coefficient
NA	Navarre	yes	yes	with country: ES	Foral cadastre; get_units
FR	France	yes	yes	yes
IT	Italy	yes	yes	yes
DE	Germany	partial	partial	partial	15 of 16 Lander: not Bavaria
AT	Austria	yes	yes	yes
NL	Netherlands	yes	yes	yes
BE	Belgium	yes	yes (slow source)	yes
PL	Poland	yes	yes	yes	TERYT parcel IDs
CH	Switzerland	yes	partial	yes	Not in cantons that publish no parcels (e.g. Vaud)
CZ DK NO FI EE	Czechia, Denmark, Norway, Finland, Estonia	yes	yes	yes
LT SI SK BG	Lithuania, Slovenia, Slovakia, Bulgaria	yes	yes	yes
LU LI IS	Luxembourg, Liechtenstein, Iceland	yes	yes	yes
CY	Cyprus	yes	yes	yes, low confidence	Few house numbers mapped
LV	Latvia	with country: LV	yes	yes
GR	Greece	with country: GR	yes	yes
PT	Portugal	yes	partial	partial	The cadastre does not cover Lisbon, Porto or Coimbra; the DGT source is often down
IE	Ireland	with country: IE (SP_ID)	partial	partial
UK	United Kingdom	no	Scotland only	Scotland only	England, Wales and Northern Ireland not yet
HR	Croatia	no	ARKOD agricultural parcels only	no	No open cadastre; not Zagreb or Rijeka
SE	Sweden	agricultural blocks	agricultural blocks	no	Not property units

Hungary, Romania and the rest of Europe are not covered: a reference or point there answers CNV_COVERAGE. Data comes from each country's official cadastre or INSPIRE service (Spain from our copy of the Catastro), so availability follows theirs; when one is down the server answers SERVICE_UNAVAILABLE, which is free.

Official registry documents (Spanish nota simple, Italian visura, Portuguese certidão permanente and others) can be ordered at catastrogps.es. They are not exposed through the API or this server yet.

Examples

Ask your agent:

Find the cadastral parcel at Calle Mallorca 213, Barcelona, and give me its area and outline.

List every flat of the building at Avenida Jose Rodriguez de la Borbolla 10, Dos Hermanas, with floor, door and area.

Is the ground sinking under parcel 30024A16000286? Is it inside a Natura 2000 site?

What is the parcel at 52.2297, 21.0122? What's its area?

Look up the Polish parcel 146510_8.0502.1/3 and tell me its area.

Compare the solar potential of these two rural parcels in Navarre and Portugal.

Compare these three parcels in Spain, France and Italy and tell me which has the best investment score.

What do land prices look like around the French parcel 75056000AB0001?

What a get_parcel call returns (shortened; values are illustrative):

{
  "reference": "9872023VH5797S0001WX",
  "country": "ES",
  "latitude": 40.4165,
  "longitude": -3.7038,
  "address": "CL MAYOR 1",
  "municipality": "MADRID",
  "region": "MADRID",
  "area_m2": 512,
  "land_use": "Residencial",
  "outline_lat_lng": [[40.41662, -3.70391], [40.41671, -3.70362], "..."],
  "google_maps_url": "https://maps.google.com/?q=40.4165,-3.7038"
}

Every call goes to the English v1 REST API (https://api.parcelgps.com/v1/...), so nested blocks such as agriculture, relief or ground_motion use the same English camelCase field names as the API docs.

Errors come back as a code plus a sentence the agent can act on, for example:

CNV_COVERAGE: That reference or point is in a country that is not covered yet.
SERVICE_UNAVAILABLE: The official cadastre for this country is not responding. Try again in a few minutes.
KEY_AUTH_004: Monthly quota used up and prepaid balance empty: top up at https://parcelgps.com/app/developer (or upgrade at https://www.parcelgps.com/developers).
