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 Security57
- 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 2 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
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability36
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Fail
- AI-judged instruction clarity (fair).Partial
- Tool/resource definitions use about 235 tokens (~47/item across 5 items; 2 tools + 3 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management37
- Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.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.
- 21 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 33 to 37. That category is still filling its 30-day observation window: 10 days of observed history at the previous scan, 11 at this one. The score rises as the window fills, whether or not the server changes.

get_forecast ~107
Daily weather forecast for a city, up to 7 days ahead: per-day high/ low (°C), precipitation chance (%), max wind, and conditions. Use for forward-looking questions — "will it rain in Paris this weekend?", "what's the weather in Bangkok next week?", packing or trip-planning questions. `days` = how many days ahead (1-7, default 5).
| Name | Type | Req | Description |
|---|---|---|---|
| city | string | yes | – |
| days | integer | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
get_weather ~108
Current weather conditions for a city, right now: temperature (°C), feels-like, humidity, wind speed, and a plain-language description (e.g. "partly cloudy"). Use for any question about the weather at this moment — "what's the weather in Bangkok?", "is it raining in London?", "how hot is it in Tel Aviv?". City name in any language; add a country for ambiguous names ("Springfield, US").
| Name | Type | Req | Description |
