## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 74/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 479 tokens (~159/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the Allergen Detector MCP server?

Allergen Detector is a hosted endpoint at https://allergen-detector-mcp.onrender.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (3)

### `check_product_allergens` (~206 tokens)

Check a product for 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".

Input parameters:

- `household` (array, required): One entry per person, each with their allergens.
- `ingredients` (string, required): The product's ingredient list, or the product page text that contains it.
- `language` (string): Language of the text, if known, e.g. "fr". Optional; helps short words in other languages be read correctly.
- `product_name` (string): Product name, for the answer only.

### `lookup_ingredient` (~112 tokens)

Look up an 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.

Input parameters:

- `ingredient` (string, required): One ingredient name as printed on a label.
- `language` (string): Language of the text, if known, e.g. "fr". Optional; helps short words in other languages be read correctly.

### `list_supported_allergens` (~32 tokens)

List supported allergens

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

## Common questions

### What is the Allergen Detector MCP server?

Allergen Detector is an MCP server listed in the public MCP registry as io.github.daniellemeng1022/allergen-detector. Checks food and cosmetic ingredients against each household member's allergies, incl. hidden names. This page covers its hosted endpoint (https://allergen-detector-mcp.onrender.com/mcp).

### Is the Allergen Detector MCP server safe to use?

Allergen Detector scores 76 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Allergen Detector MCP server expose?

Allergen Detector exposes 3 tools: check_product_allergens, lookup_ingredient, list_supported_allergens. Their descriptions and schemas cost roughly 350 tokens of context every time the server is loaded.

### Does the Allergen Detector MCP server require authentication?

No. We connected to Allergen Detector without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Allergen Detector MCP server still maintained?

Allergen Detector is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
