nyc-property-facts
Registry code: 2cf6fc453ae5b30e
Facts about New York City properties (tax lot / BBL), compiled from NYC Open Data: owner of record, building details, tax assessment, ACRIS deeds, DOB jobs/permits/violations, ECB and HPD violations, OATH tickets, HPD complaints and 311 requests.

If needs_confirmation is true, ask the user to choose a candidate BBL before requesting facts; never describe a nearby suggestion as the requested property. Apartment searches resolve to the tax…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
search_properties unknown never probed
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. Paginate with limit/offset.
{ "type": "object", "properties": { "zip": { "type": "string", "description": "5-digit ZIP" }, "limit": { "type": "integer", "default": 25, "maximum": 200, "minimum": 1 }, "offset": { "type": "integer", "default": 0, "minimum": 0 }, "street": { "type": "string", "description": "Street name, e.g. \"Grattan St\" or \"5th Ave\"" }, "borough": { "type": "string", "description": "Optional borough name" }, "house_number": { "type": "string" } } }arguments 31 lineslookup_property unknown never probed
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 and up to 4 alternatives. Use get_property for a known BBL/BIN.
{ "type": "object", "required": [ "address" ], "properties": { "zip": { "type": "string", "description": "Optional 5-digit ZIP" }, "address": { "type": "string", "description": "NYC street address, e.g. \"98 Grattan St, Brooklyn\". Units (Apt 3B), borough and ZIP are optional; a 10-digit BBL or 7-digit BIN also works." }, "borough": { "type": "string", "description": "Optional: Manhattan, Bronx, Brooklyn, Queens or Staten Island" } } }arguments 20 linesget_property unknown 54m ago
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).
{ "type": "object", "properties": { "bbl": { "type": "string", "description": "10-digit BBL, e.g. 3030090016" }, "bin": { "type": "string", "description": "7-digit BIN" } } }arguments 13 linesget_sales_history unknown 54m ago
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.
{ "type": "object", "properties": { "bbl": { "type": "string", "description": "10-digit BBL (instead of address)" }, "limit": { "type": "integer", "default": 25, "maximum": 200, "minimum": 1 }, "address": { "type": "string", "description": "NYC street address, e.g. \"98 Grattan St, Brooklyn\". Units (Apt 3B), borough and ZIP are optional; a 10-digit BBL or 7-digit BIN also works." } } }arguments 19 lineslist_open_issues unknown 54m ago
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.
{ "type": "object", "properties": { "bbl": { "type": "string", "description": "10-digit BBL (instead of address)" }, "limit": { "type": "integer", "default": 50, "maximum": 200, "minimum": 1 }, "address": { "type": "string", "description": "NYC street address, e.g. \"98 Grattan St, Brooklyn\".

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id2cf6fc453ae5b30e.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
