Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@GovAuctions MCP server search for police seized cars under $5000"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.
Eight tools on the hosted server, all read-only. The local npm package exposes the first four.
Tool | What it does |
| Search live GSA federal-surplus listings (facts only). Filter by state, category, keyword, price. |
| Fetch one live GSA listing by id. |
| Sold-price range (25th / median / 75th percentile) for a described item, across the US, UK, CA or AU government-surplus market. |
| Flip Score resale signal for a listing: estimated value, effective bid, and discount. |
| The individual archived sales behind a comp number. |
| Month-by-month sold-price trend for a described item. |
| What can and cannot be priced, by category and market. |
| Your key's usage against its monthly allowance. |

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.
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):
GOVAUCTIONS_API_KEY: required. Your key from https://govauctions.app/developers/keys
GOVAUCTIONS_API_BASE: optional. Defaults to https://govauctions.app/api/v1
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.
The tools wrap the public REST Data API. OpenAPI spec: https://govauctions.app/api/v1/openapi.json
