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 → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability76
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2339 tokens (~179/item across 13 items; 11 tools + 2 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management93
- Stability observed for 28 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage96
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 86% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "fill_transfer_note" implies "transfer" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
- An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
- Supports UI / widget rendering.Pass

construction_injury_statistics Get construction injury statistics ~120
Return a retained HSE series for construction in Great Britain: worker deaths and the rate per 100,000 workers with the long-run trend, kinds of fatal accident such as falls from height, employee deaths, self-reported and RIDDOR-reported injuries, or work-related ill health. Preserves each series’ period, units, provisional or revised status, confidence intervals, source file and publication date. This does not query a live HSE feed.

ewc_search Find UK waste codes ~200
Find UK List of Waste (EWC) codes for a waste, skip or load from one to three material words such as “plasterboard”, “mixed rubble” or “contaminated soil”, from one or more codes, or from a code prefix. Search each material separately, not a sentence; match says how many words the result covers, and a weak match returns no waste. Returns official entries with hazardous and mirror status, partner codes, source lineage and any assessment needed. Use the returned entries as candidates: origin, process and composition still determine the classification. To start a note with chosen codes, pass them to start_document.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum matched waste groups and official entries to return; defaults to 5. |
| query | string | yes | One to three material words, one or more EWC/LoW codes, or a code prefix; common spaced, hyphenated and unspaced formats are accepted. |

first_aid_requirements Estimate first-aid cover ~207
Estimate first-aid cover for each shift from HSE guidance: how many first-aiders or appointed persons, which course, whether the first-aiders already there are enough, and whether a first-aid room is worth having. Construction site by default; also factory, office, shop, nursery (EYFS) and school. Returns roles, training, shortages, practical steps, factors, source lineage and a calculator link with the same inputs.

noise_daily_exposure Calculate daily noise exposure ~233
Calculate one person’s daily noise exposure (LEP,d) from measured task levels (LAeq in dB(A)) and how long each lasts, or from dosemeter readings, and which action value it reaches (80 and 85 dB(A)). Optionally gives the weekly LEP,w, compares peak dB(C), and estimates noise at the ear against the 87 dB(A) limit from hearing protection SNR or H/M/L with each task’s C-weighted level. Do not use sound power LwA or per-shot values; omitted peak or protection measurements remain explicitly unassessed. Returns a link that opens the same calculation in the noise calculator.
