唯讀存取政府剩餘物資拍賣資料:GSA 在售標的資訊、成交價比較、價格趨勢與 Flip Score 轉售訊號。

可以做什麼
  • 搜尋並讀取 GSA 聯邦剩餘物資在售標的資訊,可依州別、類別、關鍵字、價格或距美國郵遞區號的距離篩選
  • 取得某項物品的成交價比較、批次比較,以及支撐價格區間的單筆歷史成交紀錄
  • 查看逐月中位價趨勢,以及各市場各類別的成交資料涵蓋情形
  • 取得某個標的的 Flip Score 轉售訊號:估值、有效出價與折價
  • 查詢 API 金鑰當月額度使用情形
適用情境
適合研究政府剩餘物資拍賣、估算標的轉售價值,或判斷某類別是否有足夠成交資料支撐估值。所有工具皆為唯讀,適合分析與選品,不涉及出價。
執行需求
遠端 Streamable HTTP 端點,無需安裝;本機 npm 包裝 govauctions-mcp 需 Node 18+。託管端點透過 Authorization Bearer 標頭讀取 API 金鑰,本機包裝則使用環境變數 GOVAUCTIONS_API_KEY。託管端點上成交價比較可免登入使用,其他工具需要金鑰。
安裝前請注意
估值類查詢(成交比較、成交歷史、趨勢、Flip Score)會消耗每月額度,批次呼叫按筆計費,超額可能回傳 429 錯誤。本機包裝對包括成交比較在內的所有工具都要求金鑰。資料涵蓋美國、英國、加拿大與澳洲市場,且僅限服務方已歸檔的內容。

README

GovAuctions MCP server

GovAuctions.app is a free public site for finding government surplus auctions: live listings from GSA and other government sellers, alongside what comparable lots actually sold for. This repo is its MCP server, a second front door onto the same data for agents and code.

Agent-callable tools for government-surplus auction data: search live listings, pull real sold-price comps from 170,000+ closed government auctions in the US, UK, Canada and Australia, and get a 0–100 Flip Score resale signal, from the same engine behind the site.

Tools

Eight tools on the hosted server, all read-only. The local npm package exposes the first four.

ToolWhat it does
search_listingsSearch live GSA federal-surplus listings (facts only). Filter by state, category, keyword, price.
get_listingFetch one live GSA listing by id.
get_sold_compsSold-price range (25th / median / 75th percentile) for a described item, across the US, UK, CA or AU government-surplus market.
get_flip_scoreFlip Score resale signal for a listing: estimated value, effective bid, and discount.
get_sold_historyThe individual archived sales behind a comp number.
get_price_trendMonth-by-month sold-price trend for a described item.
get_comp_coverageWhat can and cannot be priced, by category and market.
get_api_usageYour key's usage against its monthly allowance.

Get an API key (free tier available) at https://govauctions.app/developers.

Use it (two ways)

1. Hosted (remote), no install. Recommended.

Point any client that speaks remote MCP at the hosted Streamable HTTP endpoint:

json
{  "mcpServers": {    "govauctions": { "url": "https://govauctions.app/api/mcp" }  }}

Claude Code:

sh
claude mcp add --transport http govauctions https://govauctions.app/api/mcp \  --header "Authorization: Bearer gak_YOUR_KEY"

get_sold_comps answers on the hosted endpoint with no key at all; the other tools read your key from the request. See the developer docs.

2. Local (stdio) via npx

For clients that cannot add a remote MCP URL. A dependency-free Node wrapper (Node 18+) over the REST Data API, published to npm as govauctions-mcp:

json
{  "mcpServers": {    "govauctions": {      "command": "npx",      "args": ["-y", "govauctions-mcp"],      "env": { "GOVAUCTIONS_API_KEY": "gak_your_key" }    }  }}

Or download govauctions-mcp.mjs and run it with node /absolute/path/to/govauctions-mcp.mjs.

Config (env):

The local wrapper forwards every call to the REST API, so unlike the hosted server it needs a key for every tool, including get_sold_comps.

API

The tools wrap the public REST Data API. OpenAPI spec: https://govauctions.app/api/v1/openapi.json

search_listings

Search live GSA listings

Search live GSA federal-surplus auction listings (facts only — no images). Filter by state, category, keyword, price, or distance from a US ZIP code. Works signed out (up to 25 rows per page). Raw listings cover sanctioned federal sources; sold-price comps span the full market.

輸入參數qzipsortlimitstateoffsetsourcecountrycategorypriceMaxpriceMinradiusMiles

get_listing

Get a listing

Get one live GSA listing by its id (facts only). Works signed out.

輸入參數id必填

get_sold_comps

Sold-price comps

Sold-price comps for a described item, computed across the full government-surplus market in any market listed in `country`. Signed out: coverage (how many comparable sales, confidence, a coarse price band) plus `categoryStats`, the 25th/median/75th percentile of every sale in the item's category (in `state` when it has enough sales). Signed in or with an API key: the 25th/median/75th percentile for this item itself. `liveListingsUrl` links to the live auctions for the same item. A miss says which kind it is: reason `insufficient_comps` (too few comparable sales yet) is worth retrying, reason `category_not_priceable` (real-estate) never is — that category cannot be priced from a title. A catch-all `category` such as `miscellaneous` is not refused: it is dropped and the item is priced on its title alone, with `requestedCategory` and `categoryDropped` echoed back — check the resolved `category` and `confidence` before trusting the range. A miss can still carry `categoryStats` when the item's category is clear, and `retryHint` when the query was a long listing title: retry with just the brand and model.

get_sold_comps_batch

Sold-price comps, many at once

get_sold_comps for a list of items in one call. Each query is either a string ('2015 Ford F-150') or an object with its own q/category/country/state. Each item costs one valuation lookup, exactly as if sent alone; an item that comes back without a range is not charged. If the monthly allowance runs out part-way, the items already priced are returned and `batch.truncated` names the rest. Batch size is capped by plan (10 on the free allowance). Requires sign-in or an API key.

輸入參數statecountryqueries必填

get_flip_score

Flip Score

GovAuctions Flip Score resale signal for one live lot, from any source, in any market with sold-price comps (valued against that market's comp archive): estimated value, effective bid, discount, and the link to the lot on its source site. Pass the lot id as it appears in a govauctions.app lot URL. Requires sign-in or an API key.

輸入參數id必填

get_sold_history

Sold history

The individual archived sales behind an item: title, final price, sale month and state, plus the range they produce. Use when you want the evidence rather than just the number. Query-anchored — describe an item; there is no way to list the archive. Requires sign-in or an API key.

輸入參數q必填limitstatecountrycategory

get_price_trend

Price trend

Month-by-month median sale price for an item, plus the first-to-last change — 'is this category softening?'. Computed from the same comps as get_sold_comps, so it never contradicts that range. Returns an empty series when too few months clear the sample threshold. Requires sign-in or an API key.

輸入參數q必填statecountrycategory

get_comp_coverage

Comp coverage

How much sold-price data we hold per category for a market, and which categories can never be priced. Check this before building on the comps tools — it is the honest answer about what we cannot do. Works signed out.

輸入參數country

get_api_usage

API usage

This key's usage for the current month: total calls and the separate valuation allowance (which comps, sold history, trend and flip-score draw down), plus the reset date. Call it to pace a long run instead of hitting a 429 mid-task. Every other signed-in tool result already carries the same numbers in `_meta.usage`, so this is rarely needed. Free: it does not count against either allowance. Requires sign-in or an API key.

無需輸入參數。
