## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-09-20.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it.
  - 1 of 32 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: the license (MIT License) isn't a recognized OSI-approved license.
  - Actively maintained (last published 4 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 74/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 658 tokens (~164/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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 (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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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).

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (4)

### `get_product` (~153 tokens)

Get product price and stock

Get the live price, stock status, discount, variants, identifiers (SKU, GTIN) and rating of one
product page. Works with Shopify, WooCommerce, Walmart and eBay stores, Amazon in beta.

- `discount_percent`
- `extracted_at` (string): When the page was read (UTC).
- `gtin`: GTIN / UPC / EAN barcode number.
- `image`: Main product image URL.
- `image_count` (integer)

### `compare_products` (~89 tokens)

Compare products across stores

Compare 2-10 product pages side by side: cheapest, cheapest in stock, best rated, biggest discount,
price spread and whether every page sells the same product (matching GTIN). Uses 1 extraction per
URL and needs a paid CartScout plan (PRO or higher).

### `check_deal` (~135 tokens)

Check if a price is a good deal

Rate whether a product's current price is a good deal compared with its recorded price history,
with the average, lowest and highest price in the period. History builds up each time CartScout
reads the product, so a product seen for the first time has little to compare against.

Input parameters:

- `days` (integer): Period to compare against, capped by the plan.
- `refresh` (boolean): Fetch the current price first so the rating includes today (1 extraction).
- `url` (string, required): Full URL of one product page, e.g. https://www.allbirds.com/products/mens-tree-runner-nz-ochre

- `current_availability` (string)
- `current_price`
- `data_points` (integer)
- `days` (integer): Days of history analyzed, limited by the plan.

- `highest_price`
- `highest_price_at`
- `in_stock_percent`
- `last_observed_at`
- `lowest_price`
- `lowest_price_at`
- `percent_vs_average`
- `price_changes` (integer)
- `refreshed` (boolean): True when the current price was fetched just before rating.
- `url` (string)
- `verdict` (string): One-sentence explanation of the rating.

### `get_price_history` (~108 tokens)

Get price history

Recorded price and stock changes of a product page, with the current, lowest and highest price.
History exists only for products CartScout has read before; call get_product first to start it.
Does not use extractions.

Input parameters:

- `days` (integer): Days of history, capped by the plan (14 on the free plan).
- `url` (string, required): Full URL of one product page, e.g. https://www.allbirds.com/products/mens-tree-runner-nz-ochre

Output parameters:

- `currency`
- `current_price`
- `days` (integer): Days of history returned, limited by the plan.
- `highest_price`
- `lowest_price`
- `points` (array): Oldest first; a point is recorded when price or stock changes.
