Available tools 3

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

lookup

lookup_ingredient

Tell which allergens, if any, an ingredient name belongs to, e.g. "sodium caseinate" -> milk, "Prunus amygdalus dulcis oil" -> tree nuts, "DMDM hydantoin" -> formaldehyde releasers.

product

check_product_allergens

Check a product's ingredient list against the allergies of one or more people in a household. Catches allergens listed under other names (e.g. "arachis oil" for peanut, "casein" for milk, Latin plant names in cosmetics) and does not let "free from" claims hide a real ingredient. Covers food and cosmetics. Use when the user asks if a product or ingredient list is safe for someone with allergies. A result with no listed allergens is not a promise of safety: relay the limits, and never call the product "safe".

supported

list_supported_allergens

List the allergens this service can check (food and cosmetic), with the other names users may type for them.

Allergen Detector — questions

Answers built from our own checks of this server.

What can Allergen Detector do?

It exposes 3 tools, read directly from the server on our last check. Among them: check_product_allergens, list_supported_allergens, lookup_ingredient. 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 Allergen Detector 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 189 ms. The bar chart above shows every period we have measured.

How do I connect Allergen Detector?

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 Allergen Detector need an API key?

No. Allergen Detector completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Allergen Detector?

It answers our handshake in 189 ms on average, which is faster than 71% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Allergen Detector open source?

We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
