Capital-W-Holdings/us-property-parcel-real-estate-debt

**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 292,039 Massachusetts and New York parcels carry
ownership and assessed value and 95,562 recorded sale instruments cover the District of Columbia, 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. coverage_by_event_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
102 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
> **2026-09-30**. Call dfx_coverage for the same grid at the moment you read it.

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.
Then call a tool over JSON-RPC:
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:
| path | what it is |
|---|---|
| /llms.txt | the entry point, for something holding only this host name |
| /.well-known/ard.json | Agentic Resource Discovery catalog |
| /.well-known/mcp/server-cards.json | MCP server card |
| /.well-known/agent-card.json | A2A style agent card |
| /agents.txt | the agents.txt convention |
| /openapi.json | the same capabilities over plain HTTP |
| /robots.txt | crawlers and agents are welcome, and it says so |
agents.txt names no payment protocol because nothing on this server is priced.
