## Description
US government-surplus auction search, sold-price comps, and Flip Score resale signals.

## Tools
Capabilities this server exposes over MCP:

- **search_listings** — Search live GSA federal-surplus auction listings (facts only — no images). Filter by state, category, keyword, and price. (Raw listings cover sanctioned federal sources; sold-price comps span the full market.)
- **get_listing** — Get one live GSA listing by its id (facts only).
- **get_sold_comps** — Sold-price range (25th/median/75th percentile of final prices) for a described item, computed across the full government-surplus market in the US, UK, CA or AU. Available on all plans; draws down the plan's monthly valuation allowance.
- **get_flip_score** — Flip Score resale signal for a live GSA listing (valued against the full-market comp archive): estimated value, effective bid, and discount. Available on all plans (call volume varies by tier).

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

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

**Requires environment variables:** `GOVAUCTIONS_API_KEY`, `GOVAUCTIONS_API_BASE` — the values above are empty placeholders; fill in real credentials before running (see the repository for what each one is for).

## Documentation

## What the govauctions.app MCP server does

The govauctions.app MCP server connects agents and application code to government-surplus auction data. Its live inventory tools cover GSA federal-surplus listings, including searches filtered by state, category, keyword, and price. A separate lookup retrieves one listing by its identifier.

The historical pricing tools use more than 170,000 closed government auctions across the United States, United Kingdom, Canada, and Australia. They can return the 25th percentile, median, and 75th percentile for a described item, expose the individual archived sales behind a comparison, and show sold-price movement by month. The service also provides a 0–100 Flip Score with estimated value, effective bid, and discount information for a listing.

## How it works

The tools are read-only and wrap the public REST Data API. Calls can be sent to the hosted Streamable HTTP endpoint at `https://govauctions.app/api/mcp`, or forwarded through the local npm package and Node wrapper. The hosted option avoids local installation and is suitable for clients that accept a remote MCP URL.

The local process communicates over stdio and passes requests to the REST API. It requires Node 18 or newer. The local package is available through `npx`, and the repository also provides an `.mjs` file that can be launched directly with Node.

## Setup and configuration

For hosted use, configure an MCP client with the remote URL. Claude Code can add the endpoint with the HTTP transport and an Authorization bearer header. The developer service provides API keys, including a free tier, at `https://govauctions.app/developers`.

For local use, set `GOVAUCTIONS_API_KEY` in the MCP process environment. This key is required for every local tool, including `get_sold_comps`. `GOVAUCTIONS_API_BASE` is optional and defaults to `https://govauctions.app/api/v1`; set it only when the REST API base needs to be changed.

The hosted service handles authentication differently: `get_sold_comps` can be called without a key, while the other hosted tools read the key supplied with the request. The OpenAPI description is available at `https://govauctions.app/api/v1/openapi.json`.

## Tools and capabilities

- `search_listings` finds live GSA listings using state, category, keyword, and price filters.
- `get_listing` retrieves one live listing by ID.
- `get_sold_comps` returns percentile-based sold-price comparisons for a described item and supported market.
- `get_flip_score` reports estimated value, effective bid, and discount as a resale signal.
- `get_sold_history` returns the archived sales supporting a comparison.
- `get_price_trend` provides month-by-month sold-price data.
- `get_comp_coverage` describes pricing availability by category and market.
- `get_api_usage` reports usage against the key's monthly allowance.

## Limitations and notes

The govauctions.app MCP server is focused on government-surplus auction information rather than auction actions. Its tools are read-only, so the material supports research, valuation, and screening but not bidding or listing management. Live listing search is described specifically for GSA federal-surplus inventory, while sold comparisons span the US, UK, Canada, and Australia government-surplus markets.

The hosted and local deployment modes do not have identical key behavior. Hosted sold-price comparisons work without authentication, but local execution requires a key for every tool. The repository states that the local wrapper forwards calls to the REST API, so network access to the configured API base is part of local operation.

The govauctions.app MCP server is distributed under the MIT license. Its local wrapper is intended for clients that cannot add a remote MCP URL; client-specific setup depends on whether the client supports remote HTTP or local stdio configuration.
