Overview

AI-generated overview

Remote MCP server that lets an assistant look up public NYC property records by address, BBL or BIN: owners, buildings, assessments, deeds, permits and…

What you can do
  • Resolve a free-text NYC address to a tax lot (BBL) with a confidence score and match explanation
  • Fetch a full fact sheet for a property by BBL or DOB building number (BIN)
  • List open issues: DOB jobs without sign-off, active DOB and ECB violations, open HPD violations and OATH tickets
  • Retrieve ACRIS deed sales history with dates, prices, grantors and grantees
  • Search tax lots by street prefix and/or ZIP code, with pagination and open-item counts
When to use it
Useful when you need quick public-record facts about a New York City building or lot — ownership, assessment, permits, violations or sale history — for due diligence, research or tenant questions, without querying NYC Open Data sources yourself.
Requirements
A remote streamable HTTP endpoint at nycpropertyfacts.com; no package, API key, environment variable or header is declared. Network access is needed.
Before you install
Results are compiled from NYC Open Data by an independent site not affiliated with the City of New York; verify against official sources before relying on them. Apartment searches resolve only to the tax lot, not a verified unit record. When a match is unconfirmed, the assistant should ask you to pick a candidate BBL rather than assume a nearby suggestion.

Installation

In SourceWeft

  1. Open NYC Property Facts in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.jueluddinsf%2Fnyc-property-facts/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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".
