### 2026-08-05 (score 35)

First indexed and scored.

## MCP tools (6)

### `search_products` (~115 tokens)

Search purchasable products in the catalog by name, brand or SKU. Returns slug, name, brand, price and product URL for each hit. If the query looks like a color/variant code (e.g. "E00", "101"), prefer get_color_card: a code is a variant of a chart, not a product.

Input parameters:

- `limit` (number): Max results (default 8, max 25)
- `query` (string, required): Free text to search (e.g. "sketch marker warm gray")

### `get_product` (~52 tokens)

Return full detail for one product by its exact slug: name, price, availability, description, image and canonical URL.

Input parameters:

- `slug` (string, required): Exact product slug, e.g. "classic-marker-set-12"

### `get_color_card` (~80 tokens)

Return a brand variant chart (color card): every variant with code, name, SKU and — when the stock backend answers — real per-variant availability. stock:null means unknown, never assume it is available.

Input parameters:

- `brand` (string, required): Chart slug or plain brand name, e.g. "chromaflow-classic" or "chromaflow"

### `list_brands` (~28 tokens)

List available variant charts (slug, brand, product line, number of variants, base price).

### `get_promotions` (~48 tokens)

List products currently on sale. Returns up to 100.

Input parameters:

- `brand` (string): Optional brand filter
- `limit` (number): Max results (default 50, max 100)

### `get_quote` (~86 tokens)

Build a quote for a list of items and return the total plus a payment_link to hand to the human. It never charges anything: quote only, the human pays through the normal checkout.

Input parameters:

- `items` (array, required): Items to quote: each with slug (a product) or sku (a specific variant), plus qty.
- `ref` (string): Optional referral key for conversion tracking
