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 Security83
- 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 is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability72
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1208 tokens (~201/item across 6 items; 6 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 Management32
- Stability check failed: schema churn in the 14 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 0 additions. See how to fix → Fail
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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 7 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 tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. 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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_allergens Check allergens ~165
Use this when the user asks whether a product contains certain allergens, such as "does 5449000000996 contain milk or nuts?". Pass the barcode and the allergens to avoid. Returns which are listed as contained, which as possible traces, which are not listed, and whether the entry has no allergen data at all. It reads the entry's allergen tags and ingredients text, which are crowd-sourced and can be wrong: it is a data lookup, not a safety guarantee. The physical label wins.
| Name | Type | Req | Description |
|---|---|---|---|
| avoid | array | yes | Allergens to look for, such as milk, nuts, peanuts, soy, gluten, eggs, fish, shellfish, sesame |

compare_products Compare products ~140
Use this when the user wants to compare packaged foods, such as "which of these barcodes has the least sugar?". Pass one to five barcodes and optionally sugars (default), salt or kcal. Returns a ranking from lowest to highest per 100 g with each product's other nutrition, Nutri-Score and NOVA group, and lists barcodes that were invalid, not found or lacked data. Crowd-sourced data: check the physical labels.
| Name | Type | Req | Description |

get_feedback_reply Read maintainer reply to feedback ~70

lookup_barcode Look up a barcode ~142
Use this when the user gives a product barcode (EAN or UPC) and wants to know what is in it, such as "what is in 3017620422003?". Returns the product name, brands, quantity, ingredients text, the allergens and traces the entry lists, Nutri-Score, NOVA group, nutrition per 100 g, a data-quality note and the Open Food Facts link. The barcode check digit is verified first. The data is crowd-sourced and may be incomplete or wrong: check the physical label. Not dietary or medical advice.
| Name | Type | Req | Description |

Pass the words to search for and optionally a country (English name or two-letter code) and a limit of up to 10. Returns each product's barcode, name, brands and Nutri-Score; use lookup_barcode for the full entry.
| Name | Type | Req | Description |
|---|---|---|---|

How do I install the Food Facts MCP server?
Food Facts is a hosted endpoint at https://food.openkrill.app/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.

Is the Food Facts MCP server safe to use?
Food Facts scores 79 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 Food Facts MCP server expose?
Food Facts exposes 6 tools: lookup_barcode, search_products, compare_products, check_allergens, submit_feedback, get_feedback_reply. Their descriptions and schemas cost roughly 962 tokens of context every time the server is loaded.
Does the Food Facts MCP server require authentication?
No. We connected to Food Facts without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Food Facts MCP server still maintained?
Food Facts is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
