## 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 2026-09-28.

- **Endpoint Security**: 74/100
  - 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.
  - 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**: 64/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1024 tokens (~341/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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 3 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.

**Unverified: 1 category.** A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## MCP tools (3)

### `get_todays_phase` (~408 tokens)

Today's cycle phase, with workout and food ideas

Today's cycle phase, with workout and food ideas. Use when the user asks what phase they are in, what workout or food suits them today, or why their energy is up or down, for example "what phase am I in, my last period started September 12th" or "what should I train today?". Needs the first day of their last period. Not for getting pregnant, fertile days, ovulation timing, contraception or pregnancy: this is general wellbeing only, not for pregnancy planning or contraception, so suggest a doctor or pharmacist. When `period_may_be_late` is true the say line says the period may be late and suggests checking with a doctor

Input parameters:

- `country` (string): Two-letter country code (UK is read as GB). Sets the kit links (US, GB and IE get local Amazon links) and the time zone for today. Pass it for users outside the US. Default from the request.
- `cycle_length` (integer): Usual days from one period start to the next, 20 to 45. Default 28.
- `date` (string): Day to ask about, YYYY-MM-DD, a real calendar day. Default today where the user is: from tz, else country, else the request, else UTC.
- `diet` (string): Comma separated: vegetarian, vegan, pescatarian, halal. Food ideas are filtered to suit.
- `last_period` (string, required): First day of the user's most recent period, YYYY-MM-DD. Must be within the last 120 days.
- `last_period_start` (string): Older name for last_period, kept for existing callers. Use last_period.
- `period_length` (integer): Usual days of bleeding, 2 to 10. Default 5.
- `tz` (string): The user's IANA time zone, for example Europe/London or America/Chicago, so today is the user's today. Optional: country is enough in most places.

### `get_week_ahead` (~385 tokens)

The days ahead by phase

The days ahead by phase. Use when the user wants to plan training or meals for the week, for example "plan my training this week around my cycle". Returns each day's likely phase, workout focus, intensity and food focus. Not for getting pregnant, fertile days, ovulation timing, contraception or pregnancy: this is general wellbeing only, not for pregnancy planning or contraception, and it is not a fertility calendar. When `period_may_be_late` is true, `days` is empty and the say line suggests checking with a doctor

Input parameters:

- `country` (string): Two-letter country code (UK is read as GB), used for the time zone of today. Pass it for users outside the US.
- `cycle_length` (integer): Usual cycle length, 20 to 45. Default 28.
- `date` (string): First day of the plan, YYYY-MM-DD, a real calendar day. Default today where the user is: from tz, else country, else the request, else UTC.
- `days` (integer): How many days, a whole number from 1 to 35. Default 7.
- `diet` (string): Accepted for symmetry with /v1/today; the week view has no food list, so it has no effect here.
- `last_period` (string, required): First day of the user's most recent period, YYYY-MM-DD. Must be within the last 120 days.
- `last_period_start` (string): Older name for last_period, kept for existing callers. Use last_period.
- `period_length` (integer): Usual days of bleeding, 2 to 10. Default 5.
- `tz` (string): The user's IANA time zone, for example Europe/London or America/Chicago, so today is the user's today. Optional: country is enough in most places.

### `list_phases` (~69 tokens)

What each phase usually feels like, with workout and food ideas

What each phase usually feels like, with workout and food ideas. Use for general questions about cycle syncing that need no dates, for example "what should I eat in my luteal phase?". Not for conception, fertile days, contraception or pregnancy: general wellbeing only, not for pregnancy planning or contraception
