## Trust

- hygiene: 80
- liveness: 99
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-98% +updated-16d-ago -duplicate-repo(15 names)
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (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 carries no ttlMs, so clients re-fetch it

### 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 1,275 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 8 tool changes in 30 days
- fail `stability.rug_pull`: 8 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

- tools: 4, about 1,275 tokens to load them all
- tool set hash: b10892f0c7596b51a0610472543a200c
- tools last changed: 2026-10-10T11:27:40.406Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.everyai-com/recipe-scale.svg)](https://protogrid.dev/servers/io.github.everyai-com/recipe-scale)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-10 `cost_per_serving` changed (description, inputSchema, outputSchema, annotations) **meaning changed**
  - before: Calculate the cost per serving of a recipe. Use when you need to understand the cost efficiency of a recipe. Do NOT use when you need to adjust the quantity of ingredients in a recipe, use scale_recipe.
  - after: Total the cost of a recipe's ingredients and work out the cost per serving and per 10 servings. Use when budgeting a dish, pricing meal prep or comparing recipes on cost. Do NOT use to resize the recipe (use scale_recipe first, then price the scaled amounts here).
- 2026-10-10 `merge_shopping_list` changed (description, inputSchema, outputSchema, annotations) **meaning changed**
  - before: Merge multiple shopping lists into one. Use this when you have several lists to consolidate. Use scale_recipe when you need to adjust ingredient amounts for a different number of servings.
  - after: Combine several shopping or ingredient lists into one, summing the same item across lists (volumes and weights converted to a friendly unit) and noting which list each came from. Use when shopping for several recipes or meals at once. Do NOT use to resize one recipe (use scale_recipe) or price it (use cost_per_serving).
- 2026-10-10 `convert_units` changed (description, inputSchema, outputSchema, annotations) **meaning changed**
  - before: Convert a cooking amount between units. Use when needing exact conversions between same-dimension units; avoid when needing ingredient-specific conversions, use scale_recipe instead.
  - after: Convert one cooking amount between units: within volume or weight exactly, or between volume and weight using a built-in density for flour, sugar, brown sugar, butter, water, milk, rice, oats, cocoa or honey. Use for questions like 'how many grams is 2 cups of flour'. Do NOT use to change serving counts (use scale_recipe).
- 2026-10-10 `scale_recipe` changed (description, inputSchema, outputSchema, annotations) **meaning changed**
  - before: Scale ingredients from one serving count to another. Use when you need to adjust serving sizes; NOT when you need to convert units, use convert_units.
  - after: Scale every ingredient in a recipe from one serving count to another (0.1x to 20x), with kitchen-friendly fraction hints; items without a quantity pass through unchanged. Use when cooking for more or fewer people. Do NOT use to change units (use convert_units) or to combine several recipes' ingredients (use merge_shopping_list).
- 2026-10-06 `cost_per_serving` changed (title, description, outputSchema, annotations) **meaning changed**
  - before: Total the cost of the ingredients in a recipe and divide it by the servings to get cost per serving, also shown for 10 servings.
  - after: Calculate the cost per serving of a recipe. Use when you need to understand the cost efficiency of a recipe. Do NOT use when you need to adjust the quantity of ingredients in a recipe, use scale_recipe.
- 2026-10-06 `merge_shopping_list` changed (title, description, outputSchema, annotations) **meaning changed**
  - before: Merge several shopping lists into one: quantities of the same item are summed in a common unit and shown in the friendliest kitchen unit; items without a quantity are collected as notes.
  - after: Merge multiple shopping lists into one. Use this when you have several lists to consolidate. Use scale_recipe when you need to adjust ingredient amounts for a different number of servings.
- 2026-10-06 `convert_units` changed (title, description, outputSchema, annotations) **meaning changed**
  - before: Convert a cooking amount between units: same-dimension conversions are exact; cups to grams and similar need a known ingredient density.
  - after: Convert a cooking amount between units. Use when needing exact conversions between same-dimension units; avoid when needing ingredient-specific conversions, use scale_recipe instead.
- 2026-10-06 `scale_recipe` changed (title, description, outputSchema, annotations) **meaning changed**
  - before: Scale every ingredient of a recipe from one serving count to another, with friendly kitchen measures and items without a quantity passed through.
  - after: Scale ingredients from one serving count to another. Use when you need to adjust serving sizes; NOT when you need to convert units, use convert_units.
