## 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 2026-08-03.

- **Endpoint Security**: 83/100
  - 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 76/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 205 tokens (~205/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

Calculate CBM & Container Fit

Calculate total shipment volume (CBM / cubic metres and CFT / cubic feet), total weight, and how that cargo fits into standard shipping containers (20ft Standard, 40ft Standard, 40ft High Cube). Use this whenever someone asks how much space a shipment takes, how many cubic metres or CBM their boxes / pallets / cartons add up to, whether cargo will fit in a container, what container size they need, or how full a container will be. Accepts a list of items with length, width, height, weight and quantity in metric (cm, kg) or imperial (in, lb) units; returns total CBM, CFT, total weight, and per-container fill percentage with an overload flag.

Input parameters:

- `items` (array, required): The cargo line items to total up.
- `unitSystem` (string): Units for the item dimensions and weight. 'metric' = centimetres and kilograms; 'imperial' = inches and pounds.

Output parameters:

- `calculatorUrl` (string)
- `containers` (array)
- `totalCbm` (number)
- `totalCft` (number)
- `totalWeightKg` (number)
- `totalWeightLbs` (number)
