## 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 2026-10-04.

- **Endpoint Security**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1766 tokens (~294/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (83% 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.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (6)

### `check_store_prices` (~259 tokens)

Check a store's products and price changes

Read an online store's products, prices and availability, and what changed since its previous daily snapshot. Use it for questions like "track competitor prices on allbirds.com", "what did gymshark.com change?", "did this store drop prices?", "what is new or sold out at this store?". Pass store web addresses, up to 5. Works for stores on Shopify that publish their public product feed (/products.json). The store is added to a daily snapshot list, so its history builds up. Optional filters: query (text in a product's title, brand or type), limit. Returns per store the snapshot date, product count, currency, counts and lists of new products, removed products, price changes and availability changes per variant, and matching products with price, variants and availability. The first snapshot of a store has no changes to compare with.

Input parameters:

- `limit` (integer): Most products listed per section (default 10)
- `query` (string): Only products whose title, brand, type or handle contains this text, such as "hoodie"
- `stores` (array, required): Web addresses of online stores, such as "allbirds.com" or "https://www.gymshark.com". At most 5.

Output parameters:

- `stores` (array)

### `get_product_price_history` (~185 tokens)

Get a product's price history

Read how one product's price and availability moved over the days a store has been tracked. Use it for questions like "how has the price of this hoodie changed?", "when did this product go on sale?", "has this been out of stock?". Pass the store's web address and the product's link, handle or title (or part of it). Returns per variant the price, the compare-at (was) price and availability on each day something changed, from the first snapshot to now. History starts when the store was first tracked; a store never asked about before has a single snapshot. Several matching products come back as a list of titles to choose from.

Input parameters:

- `product` (string, required): A product link, its handle, or its title (or part of it)
- `store` (string, required): Web address of the online store, such as "allbirds.com"

Output parameters:

- `candidates` (array)
- `history` (object)
- `host` (string)
- `message` (string)
- `product` (string)
- `query` (string)
- `snapshotDay` (string)
- `status` (string)

### `compare_store_prices` (~577 tokens)

Compare prices and find gaps across stores

Compare product prices between two online stores to find price gaps, spreads, and margin differences. Use it for questions like "compare prices between allbirds.com and allbirds.co.uk", "find the price gap for hoodies between two stores", or "which store sells this item cheaper?". Pass source_store and target_store web addresses. Supports cross-currency comparison: when stores quote in different currencies, prices are normalized using European Central Bank (ECB) daily reference rates via Frankfurter (https://api.frankfurter.dev, checked 2026-10-02). Optional filters: target_currency (defaults to target store currency), fx_rate (manual override), shipping_allowance (freight cost deduction), duty_allowance, include_landed_duty (EU flat customs duty), query (text in title/brand/category), match_by ("title", "sku", "handle", default "title"), and min_gap_pct (minimum percentage difference, default 0). Returns matched products with local and converted prices, exchange rate, rate date and source, price gaps, percentage spreads, stock availability, canonical links, and landed margin differences.

Input parameters:

- `duty_allowance` (number): Optional flat customs duty allowance per item in target currency to deduct for net landed margin evaluation. When omitted and include_landed_duty is true, defaults to EU flat duty (€3 converted to ta…
- `fx_rate` (number): Optional manual exchange rate override (source store currency to target currency). When omitted, fetched from ECB reference rates.
- `include_landed_duty` (boolean): Whether to include estimated EU low-value consignment duty under Council Regulation (EU) 2026/382 for margin estimation.
- `match_by` (string): Product attribute to match on: "title" (normalized title), "sku", or "handle" (default "title").
- `min_gap_pct` (number): Minimum percentage price gap required to include a matched product (e.g. 15 for 15% spread). Default 0.
- `query` (string): Optional text filter for product title, brand, or category, such as "runner" or "sneaker".
- `shipping_allowance` (number): Optional estimated flat shipping allowance per item in target currency to deduct for net landed margin evaluation. Default 0.

Output parameters:

- `disclaimer` (string)
- `fx_conversion` (object|null)
- `matches` (array)
- `message` (string)
- `source_store` (object)
- `status` (string)

Read maintainer reply to feedback

Input parameters:

- `ticket` (string, required): The ticket id that submit_feedback returned.

Output parameters:

- `note` (string)
- `reply` (string|null)

Lists tool name, a plain task phrase, and the MCP URL to connect. Feedback itself is submit_feedback on this same server.

Input parameters:

- `keyword` (string): Alias for query: keyword to search.
