us-property-hazard-risk (MCP server)
A remote MCP server that assesses natural hazard exposure — flood, wildfire, earthquake, and coastal proximity — for a single US property address, using only free, keyless public data. No API keys, no database, no map. Works from Claude, ChatGPT, or any other MCP-compatible host.
Tool
assess_property_hazard(address: str)
Validates and geocodes the address, then returns flood zone (FEMA NFHL),
wildfire hazard score, seismic PGA (USGS, ASCE 7-22), fault and coastal
distance, and a deterministic 0–100 hazard_score / hazard_tier with up to
5 hazard_drivers. If a data source is unavailable, that field is reported
as unknown rather than assumed zero-risk.

Data sources
US Census Bureau Geocoder — address validation + geocoding
FEMA NFHL — flood zone
USGS Design Maps — seismic PGA
Static reference points (haversine) — fault + coastal proximity
