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 Security63
- 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 870 tokens (~217/item across 4 items; 4 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 Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 3 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

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 →
convert_ingredient Convert cups to grams for a named ingredient ~375
Converts a kitchen amount between volume and weight for a specific ingredient, using measured grams-per-cup values (USDA FoodData Central portion weights with FDC ids, and the King Arthur Baking ingredient weight chart) instead of guessed densities. 271 ingredients. Units: US cup (236.5882365 mL), metric cup (250 mL), imperial cup, US legal cup (240 mL), Japanese cup, US/metric/Australian tablespoons, teaspoons, US and imperial fl oz, pints, quarts, gallons, mL, dL, L, g, mg, kg, oz, lb and sticks of butter. Volume to volume and weight to weight need no ingredient. States which cup definition it used and cites the density source.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | number | yes | Quantity to convert, e.g. 1.5. Use decimals for fractions (3/4 = 0.75). |
| cup_system | string | – | Which cup and spoon family the bare words cup, tbsp, tsp, fl oz and pint mean. us = 236.588 mL cup (default), metric = 250 mL cup with 15/5 mL spoons, imperial = 284.13 mL cup with UK pints. Explicit… |
| from_unit | string | yes | Unit to convert from, e.g. cup, us_cup, metric_cup, tbsp, tsp, fl oz, ml, l, g, oz, lb, stick. |
| ingredient | string | – | Ingredient name, e.g. "all-purpose flour", "brown sugar", "honey". Required when converting between volume and weight. |
| to_unit | string | yes | Unit to convert to, e.g. g, oz, cup, ml. |
No output schema declared.
No examples provided.
convert_oven_temperature Convert oven temperature between F, C and gas mark ~126
Converts an oven setting between Fahrenheit, Celsius and UK gas mark (1/4 to 10, from the standard recipe table) and optionally adjusts for a fan (convection) oven by 20 C, the manufacturer guidance. Returns the nearest gas mark and whether it is an exact table value.
| Name | Type | Req | Description |
|---|---|---|---|
| fan | string | – | Fan oven adjustment. Default none. |
| from_scale | string | yes | Scale of value: F, C or gas (gas mark). |

scale_recipe Scale a recipe and convert it to grams ~253
Scales a list of recipe ingredient lines ("1 1/2 cups all-purpose flour", "2 tbsp honey", "3 eggs") by a factor or from original to target servings. Parses mixed numbers and fraction characters. With to_metric_weights, converts cup and spoon amounts to grams with the measured density table and weights to grams, and reports lines it could not match.
| Name | Type | Req | Description |
|---|---|---|---|
| cup_system | string | – | Which cup and spoon family the bare words cup, tbsp, tsp, fl oz and pint mean. us = 236.588 mL cup (default), metric = 250 mL cup with 15/5 mL spoons, imperial = 284.13 mL cup with UK pints. Explicit… |

| target_servings | number | – | Servings you want. |
| to_metric_weights | boolean | – | Also give grams for each line. Default false. |
No output schema declared.
No examples provided.
search_ingredients Search the measured ingredient density table ~116
Fuzzy search over the ingredient table (flours, sugars, fats, dairy, liquids, nuts, grains, fruit, produce). Returns canonical names, grams per US cup and per tablespoon, and the source (USDA FDC id or King Arthur Baking chart). Use it to pick the exact ingredient before converting.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum results. Default 10. |
| query | string | yes | Ingredient name or part of it, e.g. "flour", "confectioners sugar", "oats". |
