Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

lookup

lookup_property

Resolve a free-text NYC address to its tax lot (BBL) and return the property facts: summary, owner of record, building, assessment, last priced deed and open-item counts. Returns the best match with a 0-1 confidence, a plain-English confidence_explanation, a machine-readable match_type, the HTML/Markdown/JSON URLs and up to 4 alternatives. Requires "address". Use get_property for a known BBL/BIN.

open

list_open_issues

List every open item for a property: DOB jobs with a permit issued but no sign-off, active DOB and ECB violations, open HPD violations, and OATH tickets with an unpaid balance or a pending hearing. Each record has status, dates, a plain-English description and its source dataset. Requires one of "address", "bbl" or "bin".

properties

search_properties

List tax lots on a street (prefix match, e.g. "Grattan St") and/or in a ZIP code, with address, building class, units, owner of record and open-item count. Requires "street" and/or "zip"; borough and house_number only narrow the search. Paginate with limit/offset; total is the number of matches.

property

get_property

Return the full fact sheet for a tax lot by 10-digit BBL (borough-block-lot, e.g. 3030090016) or by 7-digit DOB building number (BIN). Requires "bbl" or "bin" (if both are sent, bbl is used).

sales

get_sales_history

Deeds recorded with the NYC City Register (ACRIS) for a property: date, stated price (0 = non-market transfer), grantors, grantees, and whether the deed covers several lots. Requires one of "address", "bbl" or "bin".

NYC Property Facts — questions

Answers built from our own checks of this server.

What can NYC Property Facts do?

It exposes 5 tools, read directly from the server on our last check. Among them: get_property, get_sales_history, list_open_issues, lookup_property, search_properties. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is NYC Property Facts working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 33 of 33 checks got a reply (100.0%), average response time 356 ms. The bar chart above shows every period we have measured.

How do I connect NYC Property Facts?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does NYC Property Facts need an API key?

No. NYC Property Facts completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is NYC Property Facts?

It answers our handshake in 356 ms on average, which is faster than 36% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
