Parameters

A JSON object in the request body; in an MCP client, the arguments of the tool call.

Response

structuredContent holds the result, content the same result as text for a model, and isError is true when the tool refused the request or failed; then structuredContent.code, message and hint say what to change.

{
  "structuredContent": {
    "sources": [{ "name": "...", "licence": "...", "url": "..." }],
    "downloads": [{ "label": "...", "format": "...", "url": "...", "name": "..." }]
  },
  "content": [{ "type": "text", "text": "..." }],
  "isError": false
}

Every result lists its sources with their licence. File results come as downloads: each link builds its file when opened.

Errors

A missing key answers 401, an empty balance 402, too many calls 429. A call that fails or finds nothing is not counted. See Errors and rate limits.

Description for agents

The text the server gives an agent to decide when to call this tool:

Use this when the user asks which cadastral parcel (parcelle cadastrale, plot of land) is at an address or point in France, its reference (commune, section, number) and cadastral area, or which local urban plan zone applies there (PLU or PLUi zoning: zone label, type such as U, AU, A or N, and the plan document), for example before buying land or a house or before a building project. Reads the open data of the French cadastre (DGFiP) and of the Géoportail de l'Urbanisme. Shows the parcel on a map with GeoJSON and KML downloads. France only. Never returns owners or property sales. The zone is not a building permit decision. Never use the user's current location unless they type it. Give the place as the user names it (place name, address or coordinates): this tool locates it, so find_places is not needed first. Download links build their file when opened; no file is saved. Never pass these links to open_gis_file.
