The data behind the capabilities.
Marketproof MCP gives your AI agent live access to NYC residential real estate — what's below is the data it can draw on. You ask in plain English; the agent picks the right capability and pulls what it needs.
Proprietary datasets
Built on ACRIS deeds, DOF tax rolls, DOB filings, and listing data, then linked, normalized, and enriched.
Refreshed continuously
New recordings, filings, and listing changes flow in as they're published.
Buildings & units
Condos, co-ops, and townhouses across the city, plus the new-development pipeline. Building profiles cover unit mix, amenities, developers and architects, sales history, and pricing stats; unit profiles go down to layout, square footage, and tax detail.
Ask: "Give me the full profile on 432 Park Avenue."
Listings & inventory
What's on the market right now, whether active, in contract, or recently sold. Plus shadow inventory in new developments and listings that came off the market without closing.
Ask: "Find 2-bedroom condos under $3M in Chelsea with outdoor space."
Recorded sales
Closed transactions from city records: prices, dates, price-per-square-foot, and the history of any building or unit. The raw material for comps and pricing analysis.
Ask: "List every UES 3-bedroom that closed for over $8M in the last 12 months."
Ownership & sell signals
Owners of record with the signals that matter: how long they've held, absentee and LLC ownership, pied-à-terre patterns, lis pendens, and expiring abatements. Ready-made cohorts for prospecting.
Ask: "Find 10 long-time UES owners with strong sell signals."
Contact information
Phone, email, and mailing address for owners of record, sourced from licensed data providers, so research turns into an actual conversation. Governed by our Terms, including resale restrictions.
Ask: "Pull contact info for these 10 owners and draft outreach for each."
Construction permits
DOB permits and pre-issuance filings for new buildings, demolitions, alterations, and trade work, including applicant and owner details, descriptions of work, and architectural facts.
Ask: "Show new-building permits filed in Brooklyn this year."
Brokers & deal professionals
Brokers ranked by what they actually close, plus the professionals behind recent transactions: listing agents, buyers' attorneys, lenders, and title companies, in any market slice.
Ask: "Who are the top 5 ultra-luxury brokers in Manhattan last quarter?"
Market analytics
Aggregated trends on demand: price and $/sqft trajectories, contract-signed activity as a leading indicator, and new-development supply, by borough, neighborhood, or segment.
Ask: "How has $/sqft for Tribeca condos trended quarterly over 3 years?"
How your AI agent uses it
You don't query any of this directly. You ask a question, and your agent chains the right capabilities: find the owners, pull their contact info, reference their building, draft the email. See how it works → · Browse all 18 capabilities →
