Bigiron MCP server

BigIron

Search live and confirmed-sold ag/construction/livestock/transportation equipment auctions from bigiron.com, a national US online timed-auction platform.

Part of Pipeworx — an MCP gateway connecting AI agents to 1576+ live data sources.

The sold-price gap

BigIron does not expose the realized hammer price in the page shape this pack reads. Every closed lot's amount field reads 0 regardless of bid count — verified across 100 sampled sold lots, including several with 60+ recorded bids. The live figure is served by a bidding widget (SignalR hub) this pack does not call. bigironsoldsearch still returns real, verifiably-sold lots (title, make/model/year, quantity, seller, location, close date, bid count) with finalprice: null and an explicit pricenote — never a fabricated or implied number.

buyitnowprice on active lots is a real asking** price a buyer can pay to end the auction immediately. It is not a sold comp and is labeled as such.

Data sources

a data-lot="{...}" attribute holding the full lot record as HTML-entity-encoded JSON (title, price, location, category, make/model/ year, seller, end time, buy-it-now, sale status).

• bigiron.com/Search — server-rendered ASP.NET HTML. Every lot card carries

description.

• bigiron.com/Lots/{slug} — the same per-lot record plus a free-text

Upstream quirks (measured 2026-09-13)

overwhelmingly Active — 7 unfiltered pages of "tractor" turned up exactly 1 Sold lot. filter=Sold (found via the site's own category nav links, e.g. /sale/farm-equipment-for-sale?filter=Sold) switches the whole result set to closed lots.

• page=N paginates (20 lots/page); without filter=Sold results skew

/MyAccount. It is not usable keyless; filter=Sold on /Search is.

• /Past (the site's own "past auctions" link) requires login — redirects to

the content is public and served without credentials — per Bruce's 2026-09-01 ruling ("public data is public data, regardless of robots"), this does not block building the pack. This pack crawls politely and identifies honestly via its User-Agent.

• robots.txt disallows AI crawlers by name (ClaudeBot/GPTBot/CCBot etc.), but

Quick Start

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/bigiron/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — askpipeworx, discovertools, 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.
