Propraven

jdw2111/propraven-mcp

Gives Claude and other MCP clients direct access to 180 million US parcel records through eight focused tools: lookup by address or APN, geographic search with attribute filters, portfolio resolution by owner name, hazard scoring (flood, fire, seismic), AVM estimates, permit timelines, and deed history. Each tool maps to a specific PropRaven API endpoint and includes explicit guidance on when not to use it, which helps agents pick the right one. Currently requires local setup with a PropRaven API key until the hosted endpoint launches in August 2026. Useful when you need authoritative property data in conversational workflows instead of toggling between county assessor sites or commercial data providers.

@propraven/mcp

Model Context Protocol server for PropRaven — gives Claude, ChatGPT, Cursor, and any MCP-compatible agent canonical access to 191.3M US parcels (110.0M mapped) with ownership, valuation, permits, deeds, hazard, and market data.

Hosted endpoint: https://propraven.com/mcp (Streamable HTTP, no install — docs: https://propraven.com/docs/mcp · agents + x402: https://propraven.com/docs/agents). Or run the stdio server locally (below).

Hosted (no install)

Point any HTTP-transport MCP client at https://propraven.com/mcp with your API key as a bearer header. Claude Desktop / Cursor (claude_desktop_config.json, ~/.cursor/mcp.json):
