Supplementenscanner missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

categories
list_categories
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.
cheapest
find_cheapest
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. Narrow it with filters (the category page's attribute filters, such as vegan or a form) and brand; every response lists the filters the category offers in available_filters.
product
get_product
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.
products
search_products
Search the whole supplement catalog the way the website's search box does. A product name or brand is matched typo-tolerantly (e.g. "kreatine", "theanin" still match). In markets where the site reads queries, a request described in words, with qualities (vegan, sugar-free, lab-tested, a form, a brand), is answered as that category with those filters, cheapest per unit first, and interpreted_as says how it was read and what could not be applied. Use find_cheapest instead when you already know the category.

Supplementenscanner — questions

Answers built from our own checks of this server.

What can Supplementenscanner do?
It exposes 4 tools, read directly from the server on our last check. Among them: find_cheapest, get_product, list_categories, search_products. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Supplementenscanner working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 202 ms. The bar chart above shows every period we have measured.
How do I connect Supplementenscanner?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Supplementenscanner need an API key?
No. Supplementenscanner completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Supplementenscanner?
It answers our handshake in 202 ms on average, which is faster than 67% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
