@pipeworx/swappa-prices

Daily-updated used-device prices from Swappa: current active-listing averages by variant, and realized (sold) average price per storage tier plus a sample of individual sold listings with date/condition/price.

Part of Pipeworx — an MCP gateway connecting AI agents to 1558+ live data sources.

Tools

• search_device(query, limit?) — find a device's Swappa slug by free-text name (needed by the other two tools, though they'll also auto-resolve a free-text device argument themselves).

• device_prices(device) — starting price, average (active-listing) price, and a variant breakdown table (carrier/storage → listing count, avg price, trade-in value).

• sale_prices(device, condition?, carrier?, storage?) — the realized SALE price average per storage tier (distinct from the list-price average in device_prices), plus a rolling sample of individual sold listings.

Data sources

• https://swappa.com/prices/<slug> — per-device price page: starting/average price, variant table (table.table-striped), and a "Storage Prices" table (#recent_prices, columns Storage | Avg list price | Avg sale price) — the latter is the actual realized-sale-price data.

• https://swappa.com/xui/product/<slug>/sales — htmx partial backing the "Recent Sales" slide-out; a plain HX-Request: true header (no cookie/auth) is enough — without it the endpoint 302s. Accepts condition, carrier, storage query filters (values vary per device; discover them from the <select> options in the fragment, e.g. unlocked, att, t-mobile, 128gb).

• https://swappa.com/search/quick_search?q=<query> — the site's own search autocomplete, used to resolve a free-text device name to its slug (data-product-slug attribute on data-index-name="swappa-catalog-product" links; product_group and product_sub entries are skipped — the former has no /prices/ page, the latter carries an empty slug).

robots.txt (checked 2026-09-05) disallows only /cgi-bin/ — no crawl-delay, no anti-bot page block encountered on /prices/*, /search/quick_search, or /xui/product/*/sales. Swappa's "Data Services" contact page 404'd during the survey (contact-based bulk offering, unverified) — no bulk/API terms were found linked from the /prices pages themselves during this build.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "swappa-prices": {
      "url": "https://gateway.pipeworx.io/swappa-prices/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/swappa-prices/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1558+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "swappa-prices": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-swappa-prices"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-swappa-prices

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Swappa Prices data" })

The gateway picks the right tool and fills the arguments automatically.
