Connects Claude to France's official DVF property transaction database, giving you direct access to over 10 million real estate sales records from the DGFiP. You can query transactions by location (commune, postal code, or GPS radius), pull comparable sales for a specific property, and get market statistics like median price per square meter. The underlying REST API offers endpoints for mutations, nearby searches, and aggregated stats by zone. Reach for this when you're building property valuations, market analysis, or due diligence reports for French real estate and need verified transaction data instead of scraping or manually processing raw DVF files.
