## 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 2026-09-26.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - 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**: 79/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 871 tokens (~145/item across 6 items; 5 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 67/100
  - Stability observed for 20 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 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 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 (5)

### `calculator_describe` (~35 tokens)

What Employer cost calculator computes

The inputs this calculator takes (with units, ranges and defaults), the outputs it returns, and the assumptions and tables behind it.

### `calculate` (~116 tokens)

Employer cost calculator

Run the Employer cost calculator calculator: KiwiSaver employer contribution; ACC work levy (at your rate); Holiday pay (8%, pay-as-you-go); True annual cost. Missing inputs fall back to their documented defaults.

Input parameters:

- `accRate` (number): ACC work levy per $100 of pay
- `casual` (string): Employment type
- `extras` (number): Other annual costs (benefits, equipment, insurance)
- `kiwiRate` (number): KiwiSaver employer contribution
- `salary` (number): Gross annual salary or wages

### `enquiry_describe` (~70 tokens)

What you get: an ENQUIRY with a human (not a purchase, not a guaranteed quote)

Read first. States plainly what submit_enquiry does on Employee Cost Calculator NZ: it starts an enquiry with human providers who quote directly. Nothing is bought, ordered or paid; no quote is guaranteed; it is free. Also returns who receives the details, the consent wording, and how the person confirms.

### `enquiry_fields` (~49 tokens)

The questions the enquiry asks

Every field of the Employee Cost Calculator NZ enquiry: key, label, type, whether required, help text and the allowed options where there are any. Pass answers to submit_enquiry keyed by field key.

### `submit_enquiry` (~228 tokens)

Submit an ENQUIRY to human providers (two steps; not a purchase)

Submits an enquiry to Employee Cost Calculator NZ — NOT a purchase, NOT a guaranteed quote. Step 1: call with the answers (keyed by field key from enquiry_fields) and consent=true; it validates and returns a summary, the consent line and a confirmation token — show the person the summary and the consent line. Step 2: only if the person agrees, call again with the same answers, consent=true and the confirmation token; the enquiry is then submitted, and the person receives an email with a link they must click before any provider sees it. Consent means the person has read and agreed to: "Happy for my details to go to a New Zealand accountant or payroll provider, who'll contact me directly."

Input parameters:

- `answers` (object, required): the person's answers, keyed by field key
- `confirmation` (string): the confirmation token from step 1, after the person has approved the summary
- `consent` (boolean, required): true only when the person has agreed to: Happy for my details to go to a New Zealand accountant or payroll provider, who'll contact me directly.
