Estatesales Net MCP Server

@pipeworx/estatesales-net

Upcoming estate sales, moving sales and estate auctions near a US ZIP code, from EstateSales.NET — the largest US estate-sale listing site — plus the companies that run them.

Part of Pipeworx — an MCP gateway connecting AI agents to 1864+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• estatesales_search(postal_code) — the upcoming sales nearest a ZIP: sale ID, type, city/state/ZIP, coordinates, distance, schedule, start/end dates.
• estatesales_sale(sale_id) — one sale in full: name, description, terms, every scheduled date, coordinates, picture count, and the company running it with phone and page. Street address only once the site has released it (see below).
• estatesales_companies(postal_code) — estate-sale businesses working that ZIP: name, business address, phone, coordinates, listing tier.

Auth

Keyless. No account, no token, no registration.

The official EstateSales.NET API is a different thing, and it is not usable here

EstateSales.NET does publish a documented beta REST API (https://github.com/vintage-software/EstateSales.NET-Api), and the obvious reading is that this pack should use it. It should not. That API is seller-side only — every endpoint is scoped to your own OrgId:

GET    /api/public-sales/org/{OrgId}      your org's sales
GET    /api/public-sales/{saleId}         403 without your org's token
POST   /api/public-sales/                 create a sale
PUT    /api/public-sales/{saleId}         edit a sale
POST   /api/public-sales/{saleId}/publish
POST   /api/sale-dates/ · /api/sale-pictures/

It is how an estate-sale company lists its own sales. There is no search endpoint in it at all, its keys are issued from an estate-sale company account (/account/company/api-keys), and a key would only ever return our own empty org. It cannot answer a buyer's question, so no PLATFORM_ESTATESALES_KEY exists and none would help.

What this pack reads instead is the site's own public buyer-facing data — the structured JSON the website itself renders from, no credentials involved.

Addresses are embargoed by the publisher, and this pack honors that

An estate sale is usually held at a private home, so EstateSales.NET withholds the street address until shortly before the sale (showAddress, utcShowAddressAfter, showAddressType). estatesales_sale returns the address only when the site has already published it; otherwise it returns address_published: false, the release time in address_visible_after_utc, and a note. Coordinates and city/ZIP are always present, since the site publishes those from the start.

Do not route around this. The embargo is the publisher's decision about someone's home, not a technical quirk.

No prices

EstateSales.NET lists upcoming sales. It publishes no hammer prices and no realized-sale data, so nothing here is a comp. Every response says so in a price_data field.

Data sources

• https://www.estatesales.net/{ST}/{City}/{ZIP} — city sale listing.
• https://www.estatesales.net/{ST}/{City}/{ZIP}/{saleId} — sale detail.
• https://www.estatesales.net/companies/{ST}/{City}/{ZIP} — company listing.

Things worth not rediscovering:

• The pages carry their data as JSON, not markup. Each embeds a script tag with id="estatesales-net-state" and type="application/json", holding {"NGRX_STATE": …} — Angular transfer state. Sales are at feature.cityViewState.filteredSales, a sale at feature.traditionalSaleViewState.entitiesById[saleId], companies at feature.companiesCityViewState.companies. Anchor on the script tag's id: matching type="application/json" alone also hits the analytics blocks.
• The site canonicalises its own location URLs, which is why every tool here needs only a ZIP or a sale ID. /XX/x/64111 redirects to /MO/Kansas-City/64111, and /XX/x/00000/{saleId} redirects to the sale's real path. Never hand-build the city slug.
• A city page lists 20 sales regardless of how many exist; filteredSaleCount and totalSaleCount report the real depth (e.g. 64111: 20 listed, 61 filtered, 97 total). There is no page parameter — the site loads the rest client-side. Report the counts rather than implying 20 is all.
• Dates arrive wrapped as {"_type":"DateTime","_value":"…"}; this pack unwraps them to ISO strings.
• GET /api/sales/{id} is public and keyless, but returns only bookkeeping (org id, type, timestamps) — no address, dates, description or pictures. The page state has all of those, which is why the pack uses it. GET /api/public-sales/{id} (the official API's path) is 403 without a seller token.
• /api/sales?postalCodeNumber=… answers HTTP 400 "Permissions denied on filter" — the filter is not public. That error means the endpoint exists, not that the site is down.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "estatesales-net": {
      "url": "https://gateway.pipeworx.io/estatesales-net/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/estatesales-net/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1864+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/estatesales_search \
  -H 'Content-Type: application/json' \
  -d '{"postal_code":"64111"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/estatesales_search. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Run it from npm

@pipeworx/mcp-estatesales-net is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/estatesales-net/mcp endpoint shown above. It needs network access; there is no offline mode.

{
  "mcpServers": {
    "estatesales-net": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-estatesales-net"]
    }
  }
}

Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.

It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.

Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Estatesales Net data" })

The gateway picks the right tool and fills the arguments automatically.
