## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-04.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 53/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2167 tokens (~722/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 73/100
  - Stability observed for 22 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (3)

### `sold_comps` (~720 tokens)

Sold prices for an item

What an item actually sold for on Poshmark: median sold price, typical range (p10-p90), days to sell,
        what the seller keeps after fees, price by condition, a confidence rating, and the matching sales.
        Call it for one item at a time; if it reports busy, wait the given number of seconds and call again.

        query: brand + item, e.g. "coach tabby 26" or "lululemon align leggings", or a plain item type like
            "womens jeans". For kids' clothing put girls, boys, kids, toddler or youth in the query ("girls jeans");
            otherwise kids' sizes are removed.
        size: only this size, e.g. "8", "M" or "10.5". Leave it out unless the user named a size: it can leave
            very few sales.
        condition: "new", "used", a plain word (nwt, like new, excellent, very good, good, fair, poor), or an
            exact grade: new_with_tags, not_new_with_tags, used_like_new,
            used_excellent, used_good, used_fair (comma-separated for several).
        days: only sales from the last N days (1-365). Poshmark lists sold results by relevance, not date, so
            without it the sales can be years old; days=365 (or 90) keeps prices recent.
        limit: how many individual sales to include in `sales` (default 10, 0-50). Each sale has the same fields
            as a /v1/sold item.
        exclude_seller: comma-separated seller usernames to leave out (case-insensitive).
        sort: order of the included sales: "recent" (newest first), "price_asc" or "price_desc". Stats are unaffected.
        department: comma-separated: Women, Men, Kids, Home, Pets, Electronics. "Kids" also keeps kids' sizes, and
            adds "kids" to a query with no kids' word ("snow pants" searches "kids snow pants"; query_note says so).
        category: comma-separated Poshmark categories, e.g. "Jeans".
        kids_age: only kids' sales in "baby" (0-24 months), "toddler" (2T-5T) or "big_kids" (4/5 and up) sizes.
            Kids' searches otherwise ke…

Input parameters:

- `category`
- `condition`
- `days`
- `deep` (boolean)
- `department`
- `exclude_seller`
- `include_removed` (boolean)
- `kids_age`
- `limit` (integer)
- `query` (string, required)
- `size`
- `sort`
- `source` (string)

### `buy_or_pass` (~228 tokens)

Buy or pass at a price

Whether an item is worth buying at a given cost to resell on Poshmark: buy, maybe or pass with the
        reason, judged from its clean sold comps after Poshmark's fee.
        Call it for one item at a time; if it reports busy, wait the given number of seconds and call again.

        query: brand + item, e.g. "patagonia better sweater".
        cost: what you'd pay, e.g. the thrift-store tag price, in the same currency as source (USD for poshmark, CAD for poshmark_ca).
        min_profit: smallest profit after fees worth the effort (default 10).
        size / condition: same filters as sold_comps.
        source: "poshmark" (US, default) or "poshmark_ca" (Poshmark Canada; prices and fees in CAD).

Input parameters:

- `condition`
- `cost` (number, required)
- `min_profit` (number)
- `query` (string, required)
- `size`
- `source` (string)

### `value_donation_list` (~895 tokens)

Value a donation list

Fair-market values for a whole donation list (clothing, shoes, bags and household
        goods: kitchen, home, electronics, media, toys, baby gear, pets, beauty), each item with the Poshmark sales
        behind it, a list total and a dated method paragraph the donor can keep with their
        records. One call values up to 100 items and costs one lookup per item. Call it once with the whole list, not
        once per item.

        items: a list of objects, one per item. Only description is required.
            description: what it is, as the donor would say it: "womens handbag", "mens suit", "kids snow pants",
                "Levi's 501 jeans", "KitchenAid stand mixer". Put brand and model in brand or description. Goods are
                valued only from sales of the same product, so name it as it would be listed; a count in the text
                ("throw pillows (4)") is read as the quantity.
            brand: optional, e.g. "Coach". With a brand the item is priced from that brand's own sales when enough are
                saved, else from its category.
            condition: optional. new_with_tags, used_like_new, used_excellent, used_good, used_fair, a plain word
                (like new, good, fair), or new or used. Default used, which is right for most donations.
            category, department, size: optional; read from the description when left out. A kids' size such as
                "4T" marks the item as kids'.
            kids_age: optional, for kids' items: "baby" (0-24 months), "toddler" (2T-5T) or "big_kids" (4/5 and up).
            quantity: optional, default 1. total is value times quantity.
        source: "poshmark" (US, USD, default) or "poshmark_ca" (Poshmark Canada, CAD).
        examples_per_item: how many of the sales behind each value to include (0-5, default 2). Each has a title,
            price, sold date and link.
        days: only sales from the last N days (1-3650); 365 is the last 12 months. Default: every sale.…

Input parameters:

- `days`
- `examples_per_item` (integer)
- `items` (array, required)
- `sold_after`
- `sold_before`
- `source` (string)
