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. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 973 tokens (~243/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

find_cheapest Find cheapest products ~187
Find the cheapest supplements by normalized price-per-unit within a category (and all its subcategories). This is the primary tool for "what is the cheapest X?" questions. Use list_categories first to pick a valid category_slug.
| Name | Type | Req | Description |
|---|---|---|---|
| category_slug | string | yes | The category to search within, e.g. "whey-protein" or "creatine". Products in every subcategory are included, so a parent slug like "protein-powder" works too. Get valid slugs from list_categories. |
| in_stock_only | boolean | – | When true, only return products currently in stock. |
| limit | integer | – | Maximum number of products to return (1-50). |
| market | string | – | Optional country market to query: nl, be, fr, gb, pl, es. Defaults to nl, the market this endpoint answers for. Any other value is rejected. |
No output schema declared.
No examples provided.
get_product Get product details ~121
Get full detail for one product by its id: price, normalized unit price, size, bulk/staffel tiers, buy link, and recent price history. Use the id returned by find_cheapest or search_products.
| Name | Type | Req | Description |
|---|---|---|---|
| market | string | – | Optional country market to query: nl, be, fr, gb, pl, es. Defaults to nl, the market this endpoint answers for. Any other value is rejected. |
| product_id | integer | yes | The numeric product id, as returned in the `id` field by find_cheapest or search_products. |
No output schema declared.
No examples provided.
list_categories List categories ~104
List the supplement categories that currently hold priced products, each with a live product count, store count, lowest normalized unit price, and its comparison basis (per_kg / per_serving / per_capsule). Use this to discover a valid category_slug for find_cheapest.
| Name | Type | Req | Description |
|---|---|---|---|
| market | string | – | Optional country market to query: nl, be, fr, gb, pl, es. Defaults to nl, the market this endpoint answers for. Any other value is rejected. |
No output schema declared.
No examples provided.
search_products Search products ~245
Search the whole supplement catalog by product name or brand. Typo-tolerant (e.g. "kreatine", "theanin" still match). Results are ordered by relevance, then cheapest normalized price-per-unit. Use find_cheapest instead when you already know the category.
| Name | Type | Req | Description |
|---|---|---|---|
| category_slug | string | – | Optional: restrict results to this category and all of its subcategories, e.g. "protein-powder". Must be a slug from list_categories; an unknown slug is rejected. |
| in_stock_only | boolean | – | When true, only return products currently in stock. |
| limit | integer | – | Maximum number of products to return (1-50). |
| market | string | – | Optional country market to query: nl, be, fr, gb, pl, es. Defaults to nl, the market this endpoint answers for. Any other value is rejected. |
| max_unit_price_cents | integer | – | Optional: only return products whose normalized unit price is at or below this many cents. |
| query | string | yes | The product name or brand to search for, e.g. "whey isolaat" or "magnesium bisglycinaat". |
No output schema declared.
No examples provided.
