## 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 2026-08-20.

- **Endpoint Security**: 46/100
  - 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 6 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 81/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 657 tokens (~109/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-20 (score 61, 0)

- [functional] Server version: 1.4.9 → 1.4.10

### 2026-08-19 (score 61, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-18 (score 60, 0)

- [functional improvement] Stability: unverified → 0.03
- [functional] Server version: 1.4.8 → 1.4.9

First indexed and scored.

## MCP tools (6)

### `list_base_rates` (~62 tokens)

List security base rates

Catalog of all published Quiet Failures base rates: metric id, the global question, the current global figure, sample size, severity, and every published segment slug (valid `segment` values for get_base_rate). Use get_base_rate for full detail on one.

### `find_base_rate` (~64 tokens)

Find a base rate by keyword

Search the Quiet Failures base rates by keyword (e.g. "dmarc", "certificate expiry uk", "subdomain takeover"). Returns matching metrics and their most citable segments.

Input parameters:

- `query` (string, required): Keywords to search for (at least 2 characters)

### `get_base_rate` (~122 tokens)

Get one base rate in full

Full detail for one Quiet Failures base rate segment: the figure with confidence interval, how it is measured, why it matters, the limits of the measurement, the recent time series, and the canonical source URL to cite. Segment defaults to "global"; country slugs (gb, fr, us…) and company cuts (gb-companies, gb-small…) are also published.

Input parameters:

- `metric` (string, required): Metric id, e.g. "dmarc-policy" (see list_base_rates)
- `segment` (string): Segment slug, default "global"

### `check_email_auth` (~90 tokens)

Check email authentication (live)

Live SPF, DKIM and DMARC audit of up to 50 domains the user owns or asks about. Returns a per-domain breakdown plus a portfolio grade. Compare against the base rates: most of the web fails these controls. Rate-limited per client.

Input parameters:

- `domains` (required): Domains to audit (1-50). Array preferred; a JSON-encoded array or comma/space-separated string also works.

### `check_subdomain_takeover` (~68 tokens)

Check subdomain takeover exposure (live)

Live scan of one domain: enumerate its subdomains (CT logs + DNS), then test each for dangling references on 13 cloud providers. Slow on large domains (up to a few minutes). Rate-limited per client.

Input parameters:

- `domain` (string, required): The apex domain to scan

### `check_whois` (~73 tokens)

Check domain registrations (live)

Live WHOIS lookup for up to 100 domains: expiry date, registrar, nameservers. Use to catch registrations about to lapse. Rate-limited per client.

Input parameters:

- `domains` (required): Domains to look up (1-100). Array preferred; a JSON-encoded array or comma/space-separated string also works.
