Property Intelligence MCP Server

by mosswild

๐Ÿก Open-Source Property Intelligence MCP Server

A 100% Free and Open-Source Model Context Protocol (MCP) Server for property and parcel intelligence. Powered exclusively by official public US government data APIs (USGS 3DEP Elevation, FEMA NFHL Flood Hazard REST API, USDA NRCS Soil Data Access API, EPA Facility Registry Service, USFS Active & Historical Wildfire APIs, USGS Earthquake Hazards API), open government land auctions, open county assessor GIS REST APIs, official County Recorder legal public records, FSBO portals, direct Redfin Stingray GIS APIs, and active API catalogue health diagnostics.

CRITICAL GUARANTEE: Zero paid APIs, commercial scrapers (Zillow, RentCast, RapidAPI), or subscription keys required. 100% free forever.
