## 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 2026-11-06.

- **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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 82/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1017 tokens (~101/item across 10 items; 7 tools + 3 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 74/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 10% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 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).

## Install

### How do I install the Whoppah MCP server?

Whoppah is a hosted endpoint at https://mcp.whoppah.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (7)

### `search_catalog` (~256 tokens)

Search Whoppah listings

Search Whoppah's live catalogue of curated second-hand design: furniture, lighting, art, decor and designer bags, every listing screened by Whoppah's curators. Use it when someone wants to find, compare or buy a second-hand design piece listed on Whoppah. Combine a free-text query with filters (category, brand, designer, price range in EUR, condition, colour, material, seller country) and narrow further with the facet counts in the result. Every result can be bought or bid on right now: sold, reserved and expired listings never appear. Each item carries its whoppah.com link; give the buyer that link, because buying and payment happen on whoppah.com.

Input parameters:

- `brand`
- `category`
- `color`
- `condition`
- `country`
- `designer`
- `language` (string): The buyer's language: titles come back as whoppah.com shows them in it, and links open the listing's page in it.
- `limit` (integer)
- `material`
- `page` (integer)
- `price_max`
- `price_min`
- `query`
- `sort`

### `get_item` (~174 tokens)

Get listing details

Get the full public details of one listing: description, price in EUR, condition and quality grade, brand and designer, dimensions, materials, photos, seller reference and the whoppah.com link. Pass the id (or slug) from search_catalog. Every item is a one-off, so check it here before recommending a specific piece. Only listings that can be bought or bid on right now are returned. not_found means the item has sold, expired or been withdrawn, not that it never existed: offer the buyer alternatives (search_catalog, or similar_items on a comparable listing) instead of describing it.

Input parameters:

- `id`
- `language` (string): The buyer's language: titles come back as whoppah.com shows them in it, and links open the listing's page in it.
- `slug`

### `similar_items` (~85 tokens)

Find similar listings

Find listings that look and read like a given one, to offer alternatives or comparisons. Pass a product id from search_catalog or get_item.

Input parameters:

- `language` (string): The buyer's language: titles come back as whoppah.com shows them in it, and links open the listing's page in it.
- `limit` (integer)
- `product_id` (string, required)

### `get_seller_profile` (~92 tokens)

Get seller profile

Public profile of a Whoppah seller: private or business seller, expert-seller status, and review score with recent review excerpts. Use it when the buyer asks whether a seller can be trusted. Never returns a buyer's or seller's name or contact details: a name in a review excerpt reads [name], and buyers and sellers talk through whoppah.com.

Input parameters:

- `seller_id` (string, required)

### `list_brands_designers` (~75 tokens)

Look up brands and designers

Look up Whoppah's brand and designer index, to spell names correctly, ground answers and build precise search filters. Use kind=brand or kind=designer with an optional name query.

Input parameters:

- `kind` (string)
- `limit` (integer)
- `page` (integer)
- `query`

### `list_categories` (~39 tokens)

List categories

List the marketplace categories (slugs and titles), to build precise search_catalog filters.

Input parameters:

- `limit` (integer)
- `page` (integer)

### `shipping_quote` (~74 tokens)

Get shipping options

Shipping options and prices for one listing to the buyer's country (courier, parcel or pickup), as offered at checkout on whoppah.com. Pass the product id and a country code, e.g. 'de'.

Input parameters:

- `country` (string, required)
- `postal_code`
- `product_id` (string, required)

## Common questions

### What is the Whoppah MCP server?

Whoppah is an MCP server listed in the public MCP registry as com.whoppah/commerce. Search and shop curated second-hand design: furniture, lighting, art and designer bags. This page covers its hosted endpoint (https://mcp.whoppah.com/mcp).

### Is the Whoppah MCP server safe to use?

Whoppah scores 87 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Whoppah MCP server expose?

Whoppah exposes 7 tools: search_catalog, get_item, similar_items, get_seller_profile, list_brands_designers, and 2 more. Their descriptions and schemas cost roughly 795 tokens of context every time the server is loaded.

### Does the Whoppah MCP server require authentication?

No. We connected to Whoppah without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Whoppah MCP server still maintained?

Whoppah is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Whoppah MCP server?

VerifyMCP ran 13 checks on Whoppah, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
