## 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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 66/100
  - AI-judged instruction clarity (excellent).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 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.

## MCP tools (4)

### `convert_ingredient` (~375 tokens)

Convert cups to grams for a named ingredient

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.

Input parameters:

- `amount` (number, required): 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, required): 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, required): Unit to convert to, e.g. g, oz, cup, ml.

### `search_ingredients` (~116 tokens)

Search the measured ingredient density table

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.

Input parameters:

- `limit` (integer): Maximum results. Default 10.
- `query` (string, required): Ingredient name or part of it, e.g. "flour", "confectioners sugar", "oats".

### `scale_recipe` (~253 tokens)

Scale a recipe and convert it to grams

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.

Input parameters:

- `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…
- `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, quantity first.
- `original_servings` (number): Servings the recipe makes now.
- `target_servings` (number): Servings you want.
- `to_metric_weights` (boolean): Also give grams for each line. Default false.

### `convert_oven_temperature` (~126 tokens)

Convert oven temperature between F, C and gas mark

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.

Input parameters:

- `fan` (string): Fan oven adjustment. Default none.
- `from_scale` (string, required): Scale of value: F, C or gas (gas mark).
- `value` (number, required): Temperature or gas mark, e.g. 350, 180 or 4.

## Common questions

### What is the Cups to Grams MCP server?

Cups to Grams is an MCP server listed in the public MCP registry as io.github.theluckystrike/cups-to-grams-mcp. Cups to grams for 271 ingredients with USDA and King Arthur densities, recipe scaling, oven temps. This page covers its hosted endpoint (https://cups-to-grams-mcp.lipmichal.workers.dev/mcp).

### Is the Cups to Grams MCP server safe to use?

Cups to Grams scores 68 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 Cups to Grams MCP server expose?

Cups to Grams exposes 4 tools: convert_ingredient, search_ingredients, scale_recipe, convert_oven_temperature. Their descriptions and schemas cost roughly 870 tokens of context every time the server is loaded.

### Does the Cups to Grams MCP server require authentication?

No. We connected to Cups to Grams without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Cups to Grams MCP server still maintained?

Cups to Grams is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Cups to Grams MCP server?

VerifyMCP ran 12 checks on Cups to Grams, covering TLS certificate, Authorization, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about Cups to Grams: HTTPS. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
