Tools

Tool	Description
`gunbroker_search_items`	Search active GunBroker firearms-marketplace listings by keyword (e.g. "Glock 19", "AR-15 lower", "Henri 22 rifle"). Returns matching live listings with item IDs, titles, current/buy-now prices, bid counts, and time left. Public — needs only a GunBroker developer key (_apiKey). Supports pagination and sort.
`gunbroker_get_item`	Get full details for a single GunBroker listing by item ID — title, description, prices, seller, shipping, condition, category, and time remaining. Public — needs only a GunBroker developer key (_apiKey).
`gunbroker_seller_orders`	List the authenticated seller's sold orders (GunBroker /OrdersSold) — order IDs, buyers, item titles, totals, payment and shipping status. Seller tool: needs a GunBroker developer key (_apiKey) PLUS the seller's GunBroker username and password, which are exchanged for a short-lived access token on each call.

Quick Start

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

config.json

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/gunbroker/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:

config.json

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

Both URLs reach the same gateway and the same 1476+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

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:

Code

ask_pipeworx({ question: "your question about Gunbroker data" })

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