## 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**: 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 4 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**: 80/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 345 tokens (~86/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `get_baby_age` (~92 tokens)

Get a baby's exact age from a birth date - years, months, weeks, days, totals, zodiac sign, the current and next milestone, and special-day dates (100 days, first birthday, 1000 days). Use for any 'how old is the baby' question instead of computing it yourself.

Input parameters:

- `birthday` (string, required): The baby's birth date as YYYY-MM-DD (not in the future).

### `get_milestone_dates` (~76 tokens)

Get the exact calendar date of all 25 baby milestones for a given birth date (monthly, special days, and birthdays), each with days_left and whether it is reached. Use this to add baby milestones to a calendar.

Input parameters:

- `birthday` (string, required): The baby's birth date as YYYY-MM-DD (not in the future).

### `list_milestones` (~50 tokens)

List the 25 baby milestone types this tool knows (name, emoji, day offset from birth, group). No birth date needed. Use get_milestone_dates to turn these into real dates.

### `get_zodiac_sign` (~56 tokens)

Get the zodiac sign (Western astrology) for a birth date, with element, nickname, date range, and a guide link.

Input parameters:

- `birthday` (string, required): The baby's birth date as YYYY-MM-DD (not in the future).
