DFX Intelligence MCP server

DFX Intelligence: MCP server

One connection, four domains. Real estate is the first and deepest; the same server also answers across family offices, independent sponsors and their capital providers, private companies with a transition coming, and venture capital, with cross-domain identity, relationships, events, matching and verification. See Beyond real estate.

The real estate domain answers dated questions about two things: United States commercial and federal-programme real estate debt, where loan maturities are published across 52 state codes, compliance expiries across 56 and subsidy expiries across 54, and property records, where 291,914 Massachusetts and New York parcels carry ownership and assessed value and 95,562 recorded sale instruments cover Massachusetts and New York. Call it when an agent needs to know who owns a specific building, what it last sold for, or which loans and subsidies come due in a given state and time window, with the source and the observation date attached to every claim.

Coverage is deliberately uneven and it is stated up front rather than discovered by trial.

United States, unevenly. NATIONAL: federal programme debt and maturities, LIHTC, HUD subsidy, distress and commercial tenancy. MASSACHUSETTS ONLY: parcels and ownership. RECORDED SALES: Massachusetts statewide, plus New York City deeds at or above $10m. BOSTON ONLY: permits and certificates of occupancy. coveragebyevent_type below is the measured grid, per event family, per state.

The measured per-type, per-state numbers are in Event coverage, measured below, and dfx_coverage returns the same grid at call time so an agent never has to guess from an empty result.

Endpoint: https://exchange-production-9123.up.railway.app/mcp Transport: Streamable HTTP Auth: none Registry: io.github.Capital-W-Holdings/us-property-parcel-real-estate-debt

84 tools, all free, unauthenticated and read-only: no key, no signup, no OAuth.

A tool that answers "no" clearly is worth more to an agent than one that answers an empty list, so this server refuses unknown arguments with the served vocabulary attached.

Every number on this page is measured against production, not typed. Last measured

Read the schemas before you call anything

A plain GET on the endpoint returns the full tool list, the coverage numbers and a worked example. No handshake, no session, no initialize.

curl -s https://exchange-production-9123.up.railway.app/mcp

Then call a tool over JSON-RPC:

curl -s https://exchange-production-9123.up.railway.app/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":
       {"name":"resolve_address","arguments":
        {"address":"100 Binney St","city":"Cambridge","state":"MA"}}}'

That address returns a parcel carrying a recorded sale, with the registry book and page it was recorded under.

If you are a harvester rather than a caller

The endpoint serves the discovery conventions from its own origin, so an index does not have to guess and does not have to be told:
