MCP support
Exposes sold-listing and active-listing search tools to MCP clients. It runs locally over stdio or connects through the Pipeworx gateway.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details
From the project README@pipeworx/poshmark-comps
Sold-price and active-listing search on the public Poshmark marketplace — the best open sold-price comp data on Poshmark, with no login and no API key.
Part of Pipeworx — an MCP gateway connecting AI agents to 1683+ live data sources.
Tools
poshmark_sold_search(query, department?, sort_by?, limit?)— search SOLD listings, returns price, size, brand, condition, sold date, seller, and a listing URL per hit.poshmark_active_search(query, department?, sort_by?, limit?)— same shape for currently-listed (not yet sold) items, for comparing ask vs. sold.
Auth
Keyless. No login, no API key, no anti-bot challenge encountered (verified live 2026-09-05).
Data sources
- https://poshmark.com/search — Poshmark's own public search page. There is
no separate JSON API endpoint: the page is server-rendered by a Vue app and
embeds the full result set in a
window.__INITIAL_STATE__script-tag blob (checked live: an XHR/Accept: application/jsonrequest returns the same full HTML page, not JSON). This pack fetches that HTML and extracts the embedded JSON directly — cheaper and more robust than DOM parsing.
Traps for the next person:
- One page per call, up to ~48 results (Poshmark's own default page size).
next_max_idin the response is a real pagination cursor but this pack doesn't walk it yet —total_matches_reported_by_poshmarkin the tool output tells the caller how much more exists. priceon a sold item is the listing price Poshmark shows on the sold post (what the seller was asking), not a separately verified receipt/hammer amount, and excludes Poshmark's fee and shipping. State this to callers — it's incoverage_noteon every response.sort_byonly reliably takesbest_match(default),price_desc,price_asc—newestandmost_lovedreturned empty result sets when probed live 2026-09-05; not exposed as options for that reason.brand/sizequery params on the site did not reliably filter when probed (results included non-matching brands); free-textquerydoes the real filtering, so brand/size aren't exposed as separate parameters — put them inqueryinstead (e.g."lululemon align size 6").- Crawl politely: one page fetch per tool call, no pagination loop, no concurrent fan-out.
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"poshmark-comps": {
"url": "https://gateway.pipeworx.io/poshmark-comps/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/poshmark-comps/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 1683+ 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/poshmark_sold_search \
-H 'Content-Type: application/json' \
-d '{"query":"lululemon align","sort_by":"relevance","limit":10}'
No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/poshmark_sold_search. 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": {
"poshmark-comps": {
"command": "npx",
"args": ["-y", "@pipeworx/mcp-poshmark-comps"]
}
}
}
Or run it directly to confirm it starts:
npx -y @pipeworx/mcp-poshmark-comps
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 Poshmark Comps data" })
The gateway picks the right tool and fills the arguments automatically.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
