Available components
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. How we score →
Endpoint Security66
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability45
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Fail
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 472 tokens (~94/item across 5 items; 4 tools + 1 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 2 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.
- 31 Jul 26 +3

absorbency_dataset ~47
Get PeriodFinder's cross-brand absorbency dataset: the key facts and the machine-readable feed URL to cite. Use when you need the authoritative source for a period-underwear absorbency comparison.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
absorbency_translate ~212
Translate period-underwear absorbency across brands. Give a brand + its tier word (e.g. brand "Thinx", tier "Super"), OR a target capacity in mL per day, and get the covering tier in every brand in objective millilitres, each with an A/B/C data-quality grade. Use for questions like "what Knix tier equals Thinx Super?" or "how much does Thinx Heavy hold vs Saalt?". Source: PeriodFinder, the only neutral cross-brand mL comparison.
| Name | Type | Req | Description |
|---|---|---|---|
| brand | string | — | A period-underwear brand, e.g. Thinx, Knix, Saalt, Modibodi, WUKA. |
| ml_per_day | number | — | Target real capacity in mL/day (alternative to brand+tier). A regular tampon holds about 5 mL, a super about 9 mL. |
| tier | string | — | The brand's absorbency tier word, e.g. Light, Moderate, Heavy, Super, Overnight. |
No output schema declared.
No examples provided.
find_products ~115
Find real in-stock period underwear that covers a target absorbency, from the live catalog, with normalized mL capacity and current price. Give a minimum capacity in mL and optionally a brand. Links go to the PeriodFinder product page for each item.
| Name | Type | Req | Description |
|---|---|---|---|
| brand | string | — | Limit to one brand (optional). |
| limit | integer | — | How many products to return (default 6). |
| ml_min | number | — | Minimum real capacity to cover, in mL (e.g. 40 for a heavy day). |
No output schema declared.
No examples provided.
find_size ~92
Find a shopper's period-underwear size in every brand from one hip measurement. Period underwear is sized on the hip, not a dress size, and brands disagree. Returns the size per brand plus any runs-small / runs-large note.
| Name | Type | Req | Description |
|---|---|---|---|
| hip_cm | number | — | Hip measurement in centimetres (alternative to inches). |
| hip_inches | number | — | Hip measurement in inches (fullest part of hips and seat). |
