## 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**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 68/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 863 tokens (~215/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 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 4 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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-05 (score 67, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-11-03 (score 66, +1)

## MCP tools (4)

### `lookup_ingredient_nutrition` (~223 tokens)

Look up USDA nutrients for an ingredient

Returns USDA FoodData Central nutrient values per 100 g (calories, protein, total fat, saturated fat, carbohydrate, fiber, total sugars, sodium) for a common recipe ingredient, with its FDC id, the USDA household measures (1 cup, 1 tbsp, 1 large, 1 clove) in grams, and optionally the nutrients for an amount such as 1.5 cup or 3 large. 406 ingredients from SR Legacy and Foundation Foods, embedded, no API key. Use it instead of estimating nutrition from memory.

Input parameters:

- `amount` (number): Optional amount to compute nutrients for, e.g. 1.5.
- `ingredient` (string, required): Ingredient name, e.g. "cheddar cheese", "brown rice", "olive oil", "large egg".
- `unit` (string): Unit for amount: g, oz, lb, kg, cup, tbsp, tsp, fl oz, ml, or "each" for a counted item (uses the USDA medium or large size). Default g.

### `calculate_recipe_nutrition` (~180 tokens)

Calculate nutrition for a whole recipe and per serving

Parses ingredient lines ("2 cups flour", "1 stick butter" as 8 tbsp, "3 large eggs", "1 lb ground beef"), converts cups, spoons and counted items to grams with USDA household measure weights for that specific food, and sums USDA FoodData Central nutrients. Returns per-line grams and matches, recipe totals, per-serving values, and the per-serving values rounded by the FDA Nutrition Facts rules (21 CFR 101.9) with percent Daily Value. Lines it cannot match are listed, never guessed.

Input parameters:

- `lines` (array, required): Ingredient lines, one per item, amount first: "2 cups all-purpose flour", "1/2 cup butter", "2 large eggs", "200 g chicken breast", "1 tsp salt".
- `servings` (number): Number of servings the recipe makes. Default 1.

### `round_nutrition_label` (~301 tokens)

Round values for an FDA Nutrition Facts label

Applies the FDA Nutrition Facts rounding rules from 21 CFR 101.9(c) to unrounded per-serving values: calories (under 5 = 0, nearest 5 up to 50, nearest 10 above), fat and saturated fat (nearest 0.5 g under 5 g), sodium (nearest 5 mg up to 140 mg, nearest 10 above), carbohydrate, fiber, sugars, added sugars and protein (nearest gram, "less than 1g" rules). Adds percent Daily Value from the 2,000-calorie DRVs (fat 78 g, saturated fat 20 g, sodium 2,300 mg, carbohydrate 275 g, fiber 28 g, added sugars 50 g). Rules copied from the eCFR text.

Input parameters:

- `added_sugars_g` (number): Added sugars, g per serving.
- `carbs_g` (number): Total carbohydrate, g per serving.
- `fat_g` (number): Total fat, g per serving.
- `fiber_g` (number): Dietary fiber, g per serving.
- `kcal` (number, required): Calories per serving, unrounded.
- `protein_g` (number): Protein, g per serving.
- `sat_fat_g` (number): Saturated fat, g per serving.
- `sodium_mg` (number): Sodium, mg per serving.
- `sugars_g` (number): Total sugars, g per serving.

### `scale_recipe_nutrition` (~159 tokens)

Scale a recipe and recompute its nutrition

Scales ingredient lines by a factor or from original to target servings (parses mixed numbers and fraction characters), then recomputes total and per-serving nutrition with USDA FoodData Central values and FDA label rounding for the scaled recipe.

Input parameters:

- `factor` (number): Multiply every quantity by this, e.g. 2 or 0.5. Or give servings instead.
- `lines` (array, required): Ingredient lines, one per item, amount first: "2 cups all-purpose flour", "1/2 cup butter", "2 large eggs", "200 g chicken breast", "1 tsp salt".
- `original_servings` (number): Servings the recipe makes now.
- `target_servings` (number): Servings you want.
