Govauctions MCP Server

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, and get a 0–100 Flip Score resale signal, from the same engine behind the site.

It exposes four read-only tools:

All tools are read-only. Get an API key (free tier available) at https://govauctions.app/developers.

Use it (two ways)

1. Hosted (remote) — no install

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

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

get_sold_comps is open on the hosted endpoint; the other three tools read your key from the request. See the developer docs.

2. Local (stdio) — this file

A dependency-free Node wrapper (Node 18+) over the REST Data API. Download govauctions-mcp.mjs and add it to your client:

{
  "mcpServers": {
    "govauctions": {
      "command": "node",
      "args": ["/absolute/path/to/govauctions-mcp.mjs"],
      "env": { "GOVAUCTIONS_API_KEY": "gak_your_key" }
    }
  }
}

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

API

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