Etsy MCP Server

@pipeworx/etsy

Search active Etsy listings via the Etsy Open API v3 — scoped to the three endpoints that authenticate with just an API key (no OAuth user token).

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

Tools

• etsy_search_listings(keywords?, limit?, offset?, sort_on?, sort_order?, min_price?, max_price?, taxonomy_id?, buyer_country?) — site-wide active-listing search (findAllListingsActive).
• etsy_search_shop_listings(shop_id, keywords?, limit?, offset?, sort_on?, sort_order?) — active listings within one shop (findAllActiveListingsByShop).
• etsy_get_listing(listing_id) — one listing by ID (getListing).

No sold-price / comps data — Etsy's v3 API has none. Active listings only.

Auth

BYO key only (_apiKey), requires an API key. Register a free app at https://www.etsy.com/developers/register to get a keystring + shared secret. Pass ?_apiKey=<keystring>; the colon-joined <keystring>:<shared_secret> form your "Your Apps" page displays is accepted too, and the pack handles the difference for you (see the trap below).

Etsy's v3 reference marks each endpoint's required auth. Only the three endpoints above are api_key-only; everything else (shop/receipt/user management, listing writes) requires an OAuth user token issued through Etsy's manual commercial-review flow — out of scope for this pack. If Etsy's review later grants broader access, extend this pack rather than building a second one.

Registering an Etsy developer account requires signing in with (or creating) an Etsy account and a password — a human step this pack's author cannot perform on Bruce's behalf. See the open Needs Bruce item for platform-key registration; this pack ships BYOK-gated in the meantime and its own live call has not yet been verified against a real key.

Data sources

• https://developers.etsy.com/documentation/reference/ — Etsy Open API v3. Base URL https://openapi.etsy.com/v3/application.

Traps for the next person:

• Etsy contradicts itself about the x-api-key header value, and you cannot resolve it by experiment. The api_key reference for these three endpoints documents the bare keystring; the quickstart shows the colon-joined keystring:shared_secret pair (which is really the Basic-auth credential for the OAuth token endpoint). An app awaiting Etsy's Personal Approval returns a 403 that is byte-identical to the 403 a fabricated key returns — verified with a negative control on 2026-09-09 (fleet #1279) — so no probe before activation can tell the two header forms apart. The pack therefore sends the keystring and, only on a 403, retries once with the raw value the caller passed. Don't "simplify" that back to one call until a live successful response says which form won.
• This pack returns Etsy's response JSON close to verbatim (count + results plus a source field) rather than re-mapping field names, since the exact Listing resource shape was only checked against the published OpenAPI reference, not a live authenticated response (no working key was available at build time — see Auth above).

Quick Start

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

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

What this endpoint actually serves

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

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/etsy_search_listings \
  -H 'Content-Type: application/json' \
  -d '{"keywords":"vintage brass lamp","limit":10}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/etsy_search_listings. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

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

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

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-etsy

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 Etsy data" })

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