You can query French geographic data from IGN directly through MCP by running a local MCP server that translates natural language requests into IGN API Carto calls. This lets Claude Desktop or any MCP client access cadastral, agricultural, environmental, urban planning, and administrative data with natural-language queries.

How to use

You install and run the MCP server locally, then connect your MCP client to it either in stdio mode (local process) or in HTTP mode (remote access). Once connected, you can ask in plain language for data like cadastral parcels, administrative boundaries, or Natura 2000 zones. The server handles translating your questions into IGN API Carto requests and returns structured geographic results in GeoJSON.
