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)

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

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

Claude Code:

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:

{
  "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
