Catastro Gps MCP Server

Catastro GPS MCP server

Official cadastral parcels for AI agents, across 29 European countries plus the Basque Country and Navarre (31 country and region codes), with one API key.

Ask your agent for a parcel by its cadastral reference, by a point on the map or, in Spain, by a postal address typed as free text. It gets back the reference, location, area, land use and the parcel outline, and it can estimate solar and agricultural potential, read aggregated market prices, score and compare parcels in Spain, Portugal, France, Italy and Germany.

• 31 codes, 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. A few references are valid in more than one country (some German and Portuguese numbers look alike): pass country to be explicit.
• Free-text Spanish addresses. "Calle Mallorca 213, Barcelona" becomes a cadastral reference.
• Geometry included. Parcel outlines as GeoJSON or [lat, lng] rings, with centroid and area.
• Free tier for good. 250 calls a month at no cost, no card. Failed lookups are not charged.

Claude Code

claude mcp add catastro-gps --env CATASTROGPS_API_KEY=pk_live_your_key_here -- npx -y catastro-gps-mcp

Cursor, Windsurf, VS Code and other MCP clients

Use the same npx -y catastro-gps-mcp command with CATASTROGPS_API_KEY in the environment.

Tools

Every tool call is one API call against your monthly quota, including calls that end in "not found". compare_parcels is one call for the whole comparison.

The API reports the monthly quota of your plan in the X-Quota-Limit, X-Quota-Remaining and X-Quota-Reset headers (plus X-Quota-Tier); when it runs out, the error tells you the date it resets. X-RateLimit-* is a separate per-key burst limit per minute that depends on your plan (Free 10, Developer 60, Startup 120, Growth 300; a global per-IP guard also applies) and has nothing to do with the monthly quota.

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. "Partial" means the official source does not cover the whole territory.

Data comes live from each country's official cadastre or INSPIRE service, so availability follows theirs: some national services are slow, and the server raises a clear SERVICE_UNAVAILABLE when one is down. Outside the table, a point or reference answers CNV_COVERAGE.

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.

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",
  "province": "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"
}

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 exhausted. Upgrade at https://www.parcelgps.com/developers
