## Quality 88/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 4 of 4 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,126 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 67 (weight 15)

- pass `stability.changes`: 4 tool changes in 30 days
- fail `stability.rug_pull`: 2 tools kept their name but changed most of their description in 30 days; review before trusting them
- pass `stability.new_links`: no tool change named a new site

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 1,126 tokens to load them all
- tool set hash: 0e02e9638299068ac3dd0fa7dce07ef9

### Tool changes

- 2026-10-21 `explain_additive` changed (description)
  - before: Explain what a food additive is, what it does, and its risk level, by E-number (E250) or name (sodium nitrite, Red 40, carrageenan).
  - after: Explains what a food additive is, what it does, and its risk level with sources, by E-number (E250) or name (sodium nitrite, Red 40, carrageenan).
- 2026-10-21 `find_healthier_alternatives` changed (description) **meaning changed**
  - before: Find similar products (same category in Open Food Facts) that score clearly higher than the given product. Use it when the user asks what to buy instead, or after a product scores Poor or Bad.
  - after: Finds similar products in the same Open Food Facts category that score clearly higher than the given product, best first, each with its score.
- 2026-10-21 `analyze_label` changed (description) **meaning changed**
  - before: Score a food from its label when the user shares a photo of the packaging or pastes the ingredient list and nutrition facts (also for products that aren't in the database). Transcribe the ingredient list word for word, including E-numbers and words in brackets, and copy the nutrition facts table. For US labels use basis 'per_serving' with the serving size in grams. Pass whatever is legible; the tool reports what is missing.
  - after: Scores a food from its label: the ingredient list and/or the nutrition facts, for example from a photo of the packaging or pasted text, including products that aren't in the database. Most accurate with the ingredient list exactly as printed, including E-numbers and words in brackets. Nutrition values can be per 100 g or per serving (with the serving size). Returns the same 0-100 score and reports any missing data.
- 2026-10-21 `check_food` changed (description)
  - before: Check how healthy a packaged food or drink is. Looks it up in Open Food Facts (3M+ products) by barcode or by name, and returns a 0-100 health score (Excellent / Good / Poor / Bad) with the reasons: nutrition (Nutri-Score), additives and their risk level, and how processed it is. Use this whenever the user asks whether a food is healthy, mentions a product, or gives a barcode. Prefer the barcode when you have it.
  - after: Looks up a packaged food or drink in Open Food Facts (3M+ products) by barcode or by name and returns a 0-100 health score (Excellent / Good / Poor / Bad) with the reasons: nutrition (Nutri-Score), additives and their risk level, and how processed it is. For questions such as whether a product is healthy. A barcode gives the most precise match.
